Are Easier Gears Faster?!

[@gcntech]

Do you prefer climbing at high or low cadences? ⚙

[@edoardoemiliani]

Good evening GCN, I would like to ask you an advice for my all round bike. I want to install the ultegra mechanical 11 v complete groupset on my bike: for you as a combination is it better to have a mid-compact 52-36 with 11-34 cassettes or a compact 50-34 with 11-30 cassette? Thank you very much in advance, if you can motivate it, would be even better.

[@ltu42]

@@edoardoemiliani Definitely go for a compact, unless you're worried of spinning out the hardest gear. Are you doing 80 km/h descents often? Do you ride in fast bunches on the flat? In these cases a bigger chainring might be useful, otherwise a compact gives you these easier gears without the weight penalty. Another thing to consider: in the 11 speed system, the 11-34 cassette has 2 tooth increments straight from the lowest sprocket: 11-13-15-17..., whereas an 11-30 cassette has 11-12-13-14-15-17..., giving you more gear choices on the flat. I recently got a 11-34 cassette and the larger spacing was very noticeable when riding in a group.

[@barneyklingenberg4078]

That depends on whether in or outside the saddle.

[@barneyklingenberg4078]

The 11-34 casette is just more for gravel to be fair. Personally i would rather use an more compact crank (48-31 GRX with the 11-32t casette)@@ltu42

[@chuckrodgers4780]

I would like this test done with an average cyclist and a hill that is steeper , maybe even beyond the capabilities of the rider. That’s when the expanded gear ratios will make a huge difference.

[@xuchenglin6256]

That's when you need an e-bike... try maybe EMBN??...

[@pphaneuf]

Yeah, there's a minimum cadence that's comfortable to put in a sustained effort, and lower gears might allow doing hills that would just be impractical otherwise!

[@chuckrodgers4780]

Not into e-bikes , but we are much older riders who still do centuries, but when the climbs exceed 15 % for extended periods a 28 tooth just isn’t enough anymore. 15 years ago we rode 25 tooth cassettes , that just isn’t feasible anymore.

Hi guys. I've been experimenting along these lines for the last couple of months. My take away is that easier gear /more spin is more aerobic so your energy souce is body fat more than mussle glycogen so is more sustainable, even though my over 70 body needs the occasional stop for a "blow up". After a stop the legs are fine which isn't the case when lower cadence caused the stop. So certainly spin is better. Thats why I need the "granny gear"!

[@emmabird9745]

@@Stefan_W. Hi, yes my limit used to be about 65 but 80 is achievable, even 95 ubder low load.

[@xuchenglin6256]

When you get stronger and fitter, it becomes more of a preferential choice rather than "which is better". When I was 200w and 90kg, I have to use the lightest gear and still running out of gear as a result. Later when I become much more stronger, I find that I just care less and less about gears...... Remember Power=Force*RPM, with RPM you can only go so far, from 80 RPM to 100 RPM is only 25% and to 90 RPM is only 12.5% (assume that's still within your cardio capability). That is not "next level" improvement, and you can only use it ONCE. So what if you are looking at 30% 50% 100% improvement? You have no choice but to work on your legs. When you chasing more power, let's say 300w, 330w, 350w, 400w, you can't avoid the legs, since you can't raise your RPM forever. Even though probably you'll be more aerobic capacity limited, but that's just another thing needs to addressed separately.

[@space.youtube]

"...My take away is that easier gear /more spin is more aerobic so your energy souce is body fat more than mussle glycogen..." sic ??? Let me see if I have this correct, you think aerobic activity is primarily fat fuelled instead of carb fuelled? You better tell 99% of elite endurance athlete, sports scientist and sports nutritionist that rely on constant carb replenishment to achieve success that they're doing it all wrong. 🤣

[@emmabird9745]

@@space.youtube Sorry to be trying to make it too simple. If you just keep on using body fat you will waste away, of course. Thats where refueling comes in. With aerobic effort the blood supply carries oxygen and carb fuel to the mussles. To use fat, the body turns it into carbs. When you are eating you can short circuit that. Maybe I should have said "primarily blood fueled" but then that can be confusing too. I didn't notice Alex eating in his climb, and I'm not eating in my 30 to 60 minute exercise so where do our bodies get the blood energy? I thought I was a pedant, but I'm not alone.

[@emmabird9745]

@@xuchenglin6256 I'm sure you're right, thats your zone this and that to train to get better. What the guys seem to be talking about is when you're riding to get somewhere, or to enjoy the scenery or to generally have a ride. Surely not all riding is about training, some of it is about doing the thing you were training for. Isn't that what tgis video is about?

[@chrisridesbicycles]

A thing you only touched slightly is really steep climbs. The 64 RPM Alex did with the 28T is still somewhat efficient but if you run into really steep climbs and your options are going much too hard and blow or go at a really slow cadence the difference is even bigger I think. Why not do an experiment?

[@gcntech]

Great idea! We would certainly be keen to jump back into this subject... we'll get searching for a steeper climb 🔎 Are you a fan of the lower climbing gears?

[@jahoo2k]

It seems that this test would be more valuable if done at a higher effort. 100 BPM suggests that 16 minutes at 200W for Alex is quite easy. I'd like to see this test done closer to a threshold level.

[@tihohohoho]

Yes. Or doing it on a longer climb. Riding at 64 rpm is ok for 15min but what about riding that low cadance for one or 1.5 hours.

I ride the same in the mountains. Works great and really saves the legs. The spacing on the flats is still fine. I always see to find a gear I like.

[@draugmithrin]

I still run triple chainsets (50/39/26) and 11-32 cassettes on my road bikes so I can tackle any hill or distance I want without straining my 55 year old knees or worrying about if I'm not fit/skinny enough. Needed my lowest gears on Dartmoor today, especially on Widecombe Hill.

[@packratty]

I sill have a 10 speed Ultegra triple from 2008 - wide range, small jumps, and so much less shifting the front since I have it set up so the meaty middle of my range puts me most of the time in the middle ring with a near perfect chainline. On a newer bike with a compact double and similar range, never mind the jumps between ratios, the middle of the range is a crosschained compromise of fiddling with both derailleurs. I miss the road triple.

[@ProfeTa6]

More than cadence, power, heart-rate, the main factor here is VO2 Max. Thinking of your body as an engine, you can have a lot of horsepower or a big tank of fuel but the more efficient it is, the better on the long run. A track cyclist will normally have alot of horsepower but burn through fuel faster while a tour rider can variably have different strengths depending if more of a climber, sprinter, time-trialist, classics rider etc. I argue that there is no "higher/lower cadence is better/worse". Mostly rider fitness dependent.

[@stefanwagener]

For long distance trips (4 to 10h) easier gears make me less exhausted, but probably through the effect by putting more power out when in higher gears uphill. With higher gears it is often not possible to stay within my FTP range and going above means fatiguing earlier. So easier gears help me a lot to go on longer trips. Actually, I replaced my 11-34 (11s) with a 11-40 (beyond spec) combined with 50/34. Now climbs of 12% aren't that exhausting anymore and I can sustain several of them throughout a day trip.

[@silverburn55]

52 yrs old, living in Switzerland, with multiple heart stents. Lower cadence = lower HR, which is my objective. A higher cadence (70prm+) just feels unnatural and pushes the HR higher. If anything, its slower for me.

[@xosece]

while I advocate lower gears, this video has been an eye opener. I mean, the lowest cadence = less strain in your heart. I love to use the lower gears in my MTB but this video is very informative 'cos the idea is to use them at a slower pace. Since I have a 22/30/40 11/34 MTB, after watching this video I might try a nice gravel like, dunno about the model, but it must be 1X with lower gears, something like 38/42, 38/44 or even lowest than that.

[@dblissmn]

53 and just coming off valve repair surgery; I'm not entirely sure that lower cadence equals lower HR even if it is overall correlated with it; there are many other variables. Eight months out from the surgery, there's nothing quite like pushing a high gear up a hill to spike the heart rate and while the onset is marginally slower than with low gear and high cadence, it takes much longer to recover from the high gear with low cadence interval. You recover faster from the high cadence interval because your muscles aren't as fried as they would be from mashing the bigger gear. So I am in general trying to train myself into a higher cadence over time. Overall, I feel like this video is like only half the exercise you need to do to answer the question!

[@jebrossard]

One of the reasons I went with a gravel bike as my first drop bar bike was the gearing. 11 speed 11-34 with 46/30 chainring. I'm 67 and this gearing is awesome.

[@declanfaughey8471]

Get gear ratios that suit you and stop trying to impress your mates. I run a 50-34 chain rings and a 11-32 cassette as that is perfect for me as I live near the blackstairs mountain range.

[@nuttycommuter3718]

When I built up my bike, I spec’d it with a 52/36 and it quickly became apparent that I wasn’t using the smallest 3-4 cogs so swapped it out for a 50/34 and am much happier. Easier on the hills and am actually using the cassette I paid for

[@jbraxton3065]

The first real bike I had was a Trek 1000 (rebuilt with mostly Campagnolo parts). It had a 53/39 front and a straight block cassette 13-18. Did a ride that included a 20 mile 4,800 foot vertical increase with 6% average grade. It was a lot of work to keep the cranks moving, but well worth it coming back down.😄😄

[@alexandranedela6250]

Great video! My husband changed my road bike cassette to a much bigger one and it has been hands down the best improvement ever done to my bike ( other than a bike fit). I live in Ireland and love doing hills, so an easier gear ratio meant that I could go on much longer spins with steeper hills with less fatigue. ❤

[@a1white]

I know we keep advocating “spinning to win” but research has shown (as you’ve mentioned in other videos) that there isn’t a set high cadence that works well for everyone. Some people are more efficient at cadences less than 80rpm. I’m an advocate for cycling at radios and gears that work for you, as an individual

[@FoxFox-i1c]

Nice to see all the comments from riders who switched to gears witch suit their needs. I like to have a “spare cog” when things get tough. Or when I take my bike frim the road to gravel. I myself ride an 50/34 front with a 11/34 or 11/40 rear. Yes an ultegra 8000 long cage rear derailler can take a 11/40.

[@emiliorossi1841]

I already use grx (46/30 11/36) on my road bike. It is amazing especially since I do long rides bordering on ultra distance.

[@patoberli]

Which is why I just upgraded from 11-42 to an 9-46 (E13) cassette and the front ring from 40 -> 38. Climbing is so much easier now and more enjoyable. Yes the steps between the gears are larger now but I'm not driving a race where I need the perfect cadence.

The spacing on the Ekar is actually smaller on the top-end then with an 2x set-up. Since you are using an smaller chainring at the front. But on the climbing gears yes the spacing is fairly large.

[@petesmitt]

When the 1 x cranksets became popular with mountain bikes, the cassettes became massive dinnerplates, with as much as a 52 tooth rear cog; I only ride easy trails and while I like the 1 x cranks, I don't need the easy gears provided by the dinnerplate cassettes; when I checked the cogs of my 10 - 51 teeth 12 speed cassette, I noticed that removing the 4 big cogs I never used and the 1 small cog I never used, left me with exactly the same number of cogs and ratio's of a 7 speed cassette, (10-12-14-16-18-21-24-28-33-39-45-51), which is also much lighter, cheaper, better chain-line, than the 12 speed; Shimano Acera 7 speed weighs 225g, Shimano SLX 12 speed weighs 534g; the price differential, 12 speed is 6 times more expensive than 7 speed.

I use 46-30 with 11-34 casette. I am not PRO to ride 50 or even 53 crank, 46 is enough for nonpro rider :D

[@thenoodlehunter6828]

Funnily enough. I put in a bike chart which calculates speed at cadence. 46x11 @ 100rpm = 52.5km/h, 50x11 @ 91RPM = 52.7km/h, 52x11 @ 88RPM = 52.4km/h This makes me conclude that most recreational road riders could even use an easier gears, and spin faster and still keep up at a social pace on a road bike. I am definitely a spinner, so it's good food for thought!

A bigger chainring helps you stay in the middle of your cassette for most of the rides improving le chainline.

[@stephenandruski1087]

My mantra has been "downshift and spin" for decades. I agree that different people may have different "natural cadences", but I think most people are grinding too much. the best explanation I've heard is that at low cadence and high power output your body uses more muscle glycogen. Once that's gone, you're done. At a higher cadence your body is using more blood sugar that is easily replenished. I don't know if that's ever been tested, but I think many of us have seen anecdotal evidence for this. There's also the knee stress aspect to consider.

[@raykleiner3151]

I went through this whole process myself last week. As an MTBer for over 30 years, I recently bought a used road bike with 53/39T Dura Ace x 11-25 cassette (10 speed). After much deliberation, opted for a compact Tiagra 50/34T with a new 11-30 cassette. Still experimenting with both the 50 and 34 rings to find that sweet spot. It really depends where you live and what you ride. I live south of Milan, so there are some nice demanding passes where I ride just 30 kms from here, even though around Milan ii is as flat as a witches....

[@michiganstate149]

As a 220lb rider, essier gears mean lower power zones for climbs which means more time to be able to hold those zones and power for climbs. Sometimes to keep upright its 300-400+W. If i can reduce a previous bailout gear down to do 20-30w less, then it will be faster overall, less fade during the ride snd the ability to hammer at other spots that aren't climbs.

[@TheBridgee100]

On long endurance rides with a lot of climbing the larger cassettes with spinning higher cadence works a treat and saves the legs. This while still providing the option of a slower cadence on a harder gear for the flats and rolling hills. You get the best of both worlds. I don't ride the same cadence on a ride due to the varying road conditions and wind. I like the versatility that a larger cassette offers.

[@robmagee100]

The pedal stroke efficiency curve seems nearly logarithmic to me, taking more and more power to maintain cadence as rpm’s approach maximum. I remember Mark Gorski (1984 Olympic Gold Medalist in the Sprint) talking about attempting to reach 200 rpm with zero resistance to raise that stroke efficiency. I think most of us experienced riders start using more power to maintain the cadence than goes to the wheels around 90 to 100 rpm, but that’s just a guess. Inexperienced riders are probably most efficient (and more limited) at 60 -70 rpm. Practicing the spin to extend that usable cadence is under appreciated and hugely beneficial in my opinion. I don’t know how, but actually measuring those factors might be eye-opening.

[@chubbyman6929]

This is so helpful information guys. This info is also helpful to those using cycling as a fitness starting strategy. We may not have the developed muscle to go fast but building the cardio fitness first, we don't reach 'the bonk' stage too quickly while still enjoying the ride and scenery. Legs give out while the heart shouldn't do so, hopefully.

[@mischief2168]

Thanks for an interesting video. Age of rider though! I'm a 66 year old rider with some long covid complications. My heart rate is now higher on climbs than before, also my breathing less good. I find high cadence riding more difficult than before. I have easy gears (36 / 32) but a lighter bike (6.6kg Emonda) with stiffer wheels (Campag Shamals) has helped me more that swapping cassettes. ''Light bikes are mint'' said OB recently, and I agree. For me getting out of the saddle and using my legs is more efficient, though I'm neither Feather or feather-weight.

[@turboseize]

​@@thomasmitchell6609 Joints, too, need some degree of stress. Cartilage is nourished by synovial fluid, and this works best by moving the joint through it's full range of motion against a load that is heavy enough to compress and sort of "sqeeze out" the cartilage, so that the cartilage then can "suck in" fresh synovial fluid when it decompresses. Lack of movement will lead to degradation of the cartilage and eventually ossification of the unused areas, which will then restrict range of movement even further. That's why training OFF THE BIKE, especially strength training and some mobility work (mobility is more than just stretching!), is so important.

[@thomasmitchell6609]

There's stress and then there's UNNECESSARY stress. I wouldn't dream of telling you how to deal with your respiratory problems, caused by a communicable disease. But for anyone to omit using lower gears to spare their knees and, in most cases, to improve circulation and respiration would be, to say the least, unwise. I'm guessing that you have yet to struggle with osteo-arthritis in your knees. I hope you never do. But knee pain, from pushing high gears, kept me from cycling for a long time and that was not good for arthritis or respiration and circulation @@turboseize nnecessary

[@turboseize]

​@@thomasmitchell6609 Our opinions probably differ only in nuances. You are of course totally correct that, especially with endurance exercise, to high a load over prolonged time can and often will lead to overuse injuries. My point was that load in itself is not bad for the joint, but rather required for it to stay healthy. Mashing to high a gearing for decades may lead to issues (with joint cartilage, the menisci, even some tendons), while a few sets of heavy deep squats, counterintuitively, might help to prevent them. After all, it's not only about the force, but also the volume. A couple sets of heavy squats will be 50 reps per week. Grinding to heavy gears on a bike, the actual force will be much lower, say about a quarter of that of a heavy squat, but the repetitions per week won't be in the double digits as with the squats, they will be in the tens or even hundreds of thousands.

Depends on your physiology and muscle fiber type. Look at your average cadence, ride after ride after ride. Your natural chosen cadence will obviously present itself. Mine's 77. It's always 77. It might tick up a little on climbs or harder efforts, but whatever I need to use near that cadence on climbs, that's the gearing I want. Some will use lower cadence, some will use higher. If you have a riding buddy who's cadence is higher/lower on climbs, try to match theirs for a time and see what it feels like. It can be shocking how uncomfortable a higher or lower cadence can be from your natural preference.

I can definitely confirm the "harder gear is more muscular, easier gear is more cardiovascular" theory, as my tri coach has been preaching that for years.

[@matteodiluce9387]

Absolutely agree. Plus it gets interesting on really long climbs and longer rides with a lot of vertical. The easier gears save your legs for later. I lately used my gravel bike with gp 5000 tires for riding in the Alps. The 40:42 ratio worked amazingly, especially on climbs with up to 23% gradient.

Whether I go for high cadence or low cadence on a climb depends on how I'm feeling for that particular climb. Sometimes switching between the two in the middle. Just depends on whether I feel like my lungs or legs can take it better at that time.

[@leomaduro8661]

In my opinion easier gearing has been a far more important innovation than some other items that get all the attention. I used to do the Ardennes classics for fun not as a pro or amateur cyclist and back then 42x24 was your easiest gear. In 2001 I was in Spain and France, going to 2000 m several times, with 25 kg of baggage on a $500 MTB, with 42-32-22 chain set. A largest cog of 26 was more than enough to take on any 2000 m mountain pass. The way the pros nowadays attack the very steep climbs has some relationship to better training, nutrition, etc. but also with gearing we could not dream of back then. Cycling, especially long-distance races or tours is all about saving energy AND sparing your muscles and knees. Having nowadays gearing makes cycling so much more enjoyable, also for the elderly among us who love to stay active. I don't even think about e-bikes yet...

[@redalert2834]

It's very important that you go to Mallorca if you ever get the innovative idea that changing to a lower gear might help you climb hills. There are no hills anywhere else on the planet and increasing your carbon footprint helps people make more bike parts from carbon-fibre.

[@jaredfontaine2002]

Rim brakes, 1:1 25 mm tires, use 1:1 when it is 15% or plus. Then back down to the 28 or 25 when under the 6%. Or if you are feeling your cheerios put it in the big dog and dance like Contador

[@MyBetsie]

Taking riders trained to push a gear and getting them to go at 87rpm is interesting. Train for 90rpm and it becomes easier and easier, train for 100rpm and that 85ishbrpm becomes so much more natural as your CV system improves. Have both low cadence high leg power and higher cadence and you can switch between them to rest one a little whilst using the other. Has to be a win win.

My newest Carbon Fiber Road bike has a 53/39 crank and a 11x30 cassette. I typically ride on hilly roads in South Carolina. For that terrain, the gearing works well. I took a cycling trip to the Big Island of Hawaii where the climbs are long and very steep 15% to 20% flattening out to 9% and then back up again, for several miles at a time. For that environment, I used a 50/34 crank and 11x32 cassette (biggest I could go with a short cage) and I was able to get by. For the longer, steeper climbs, the lower gearing is a huge help. Not sure I could have done it with the larger crank and smaller cassette. I've also learned ( and trained) to keep my cadence at a higher pace in general. I target 85 to 95 RPM average with sprints over 100 RPM. Spinning is definitely faster than grinding and can be sustained longer. Great video!

[@erents1]

As an old school mountain rider I’ve relied heavily on low gears on road but obviously more so racing in the dirt. I find that the advantages are; some psychological relief on long steep climbs, a lessening of lactic acid in my legs and more oxygen into my lungs. I also find that I have fewer post ride cramps in my legs if I can have a higher cadence when needed. I would find myself using a zig zag accent in order to lighten the extreme steepness of the terrain, thereby imitating a higher gear for added recovery. Great video!

[@xanthoptica]

For off-road (or on a rough road) it can be hard to spin efficiently when the bike is being bounced around. If you are pedaling so fast that you get "micro-bucked" going over a root or a bump then you're converting forward momentum into lifting your body weight...not very efficient.

[@mathewrose2951]

On rides with up to 1000m of climbing and under 60km in length, the easier gear is more of a "want" than a "need" on the steep bits. Into the third hour or a ride, though, if we've logged 1500m or more uphill and there are more climbs to come, I'm spinning to save my (soon to be 50 year old) knees since I got all of the muscular work I could want out of hours one and two. It also helps to prevent a cramp on warm days, I find, if you're spinning instead of grinding it out with fatigued muscles.

[@jameslee-pevenhull5087]

Power for Velocity is independent of gearing. Gearing is decided by your individual muscle type and how you have trained. For example, I grew up on 52/42 with 13 to 23 screw-on freewheels. My first geared bike at 12 years old was a 48 chainring to a 14 to 28, 5 speed screw-on block. With 26" wheels, a 45" gear was supposed to be workable for a youth. The result is now at 63 years old, a 10% hill is no problem on a vintage bike with 48 single ring and 28 sprocket. Rode up a couple of 15% conks today. Strava said 236 W.

[@BC-wj8fx]

I have always run 9-speed 11-34on the rear and a triple up front. I've never wished for more in-between gears. Early on I discovered switching between leg load and cardio load. Alternate between the two to give the other some recovery. I train at the most extremes, e.g. 5km circuit at 60 rpm, then again at 115 rpm, repeat a few times.

[@brianawd]

I just went from a 53/39 front and 11/28 rear on my tri bike to 1x with a 50front testing 2 different cassettes now 10/33 and 10/36. So far the 10/36 is working really well for me. I made the switch because I found even on my triathlon races I almost never used the small 39 front on my 2x even when climbing some decent hills.

[@flageolett]

I remember 1989 where in an US cycling magazine they reported about a study, that at 50% of your maximum force 90% of the circulation in the muscle is blocked. This reduces the time and blood volume for energy and waste transportation. Ever since then, I try to use lower gear ratios with higher cadences even if it does not look very "cool". But I have the impression, that it was and is good for my training and racing.

[@bihlygoat]

Something I learned mountain biking has also carried over to road biking. If my legs are burning but I’m not breathing very hard (have some HR reserve), I use an easier gear to spin faster. If I’m breathing really hard but my legs feel good, I use a harder gear to slow my cadence down. Of course, if my legs are burning and I am huffing and puffing, I just have to slow down 😂. I like having the big gear in the back just to have the option on steep sections, or to recover on a climb if I go too hard and blow up. I think the optimal cadence is different for every rider, though not as much different as some people think.

[@xuchenglin6256]

Great effort! Finally you guys found your lost power meter and did those tests again with controlled POWER. Your test result in this video is very inline with my experience that it's a load transfer between muscular and cardiovascular systems. And is very inline with the scientific research in this field that shows the most efficient RPM is about 60. I want to add that there's a difference between "max efficiency" and "max sustainability". Though low RPM is more efficient, the time to fatigue could be much shorter than the high RPM, even though the RPE is lower. So for sustained effort a lot of people find that high RPM is actually more easier, even though "feeling harder". I guess another thing is when you want to get really fast, like 50% 100% improvement, you can't avoid the leg force. You can only increase your RPM so much. If you are looking at 20%+ 30%+ 50%+ or 100%+ improvement, you have to work on the legs. (given that cardio is unlimited, that's another topic).

[@andrewlovett5001]

Deep into a climby Fondo I was not regretting my switch to accomodate 33-36 instead of 35-33. Used it for a lot of the final climb - 180-200W with a comfy cadence of 80-85 on consistent 7-10% sections

[@jasondoust4935]

I concur and volunteer my results for the average rider test. I've just bought a carbon gravel bike with hard pack tyres. On tarmac I keep the pressure higher and having the low ratio gearing means that I can climb longer and have legs in reserve to stand up and pump out some extra wattage if required. (Which is a nice feeling when you're 55 and getting your fitness back.)

Spin To Win 💫

[@mpvsystems9302]

The optimal cadence is a function of power output such that overall efficiency is maximized and the load on the aerobic system is balanced with the load on the muscles. For example, every hour record has been set with a cadence of about 105 RPM. Track Sprinters go much higher when delivering 1000+ watts to the pedals. We see climbers like Feather climbing mostly out of the saddle using the slowest possible cadence that allows them to just barely stay on top of the gear. The data from your test suggests that the 28 tooth cog is more efficient than the 34 at 200 watts. Also, transmission losses as wells as 'gear gap' increase significantly with cogs smaller than 13 teeth making them undesirable at best. Lots to consider.

[@Gixer750pilot]

“Spin to win, dance like lance”. DurianRider just exploded

[@bjornkinding6998]

Hello GCN, and thank you for your channel! I'm love your information, I trust you, and I learn so much. Your last sub-scientific research though,... There are a lot of holes in the collection, analysis, and evaluation of data. With that said, it still contains valuable information for me. That you subjectively can state that you with two so drastically different cadences can generate the same power and maintain the same speed, and thereby shift the workload/fatigue between legs and the heart, is a great skill to have. Personally, my technique is to poor to generate any high level of power when cycling with a high cadence. That less resistance doesn't fatigue the muscles as much as high resistance is of course nothing new. Lifting 100 kg once does not has the same impact on your muscles as lifting 20 kg five times. But to generate the same power, you need to do the five reps in the same time as you did the one rep. And that's where the higher-lower cadence equation has a ceiling and a bottom, and those are different for each individual.

[@albertomorales3241]

One aspect you guys completely gloss over is that you are using a Dura Ace 9250 with a Shimano 105 11-36 cassette! That is awesome! I googled everywhere and no one is saying you can do this, so you should tell folks that this is pretty straightforward, or did you guys have to mess with hangers and such? I usually push the boundaries also, and have been using a 52-34 chainring, but I love the idea of getting a 1x1 gear ratio and keep the 52-36 which is so much better shifting.

[@elizabethpoley6882]

My new Specialized Roubaix bike build has a Leonardi General Lee 9-50t, 12 speed cassette w/a 32 chainring. I used to spin out w/a 34 chainring, but my local bike shop owner assures me that the setup we went with will get me up these big hills around here. I haven't been able to test this out yet. I think I'm going to need a 34 or 36 chainring in the future after knee replacement surgery, but that remains to be seen. Originally, I wanted 13 speed, but was told the parts would be too hard to source if there was a breakdown.

[@ysarn]

Erm, I think you have shown from your video that when Alex was using the smaller gear on the second run, 36/36, he was under-geared. Using too low a gear at low power is inefficient. It is best to use the correct gear for the grade of hill you are going up at the fitness and power that you can do. I have seen studies that say that if you are cycling at a low power output that it is better to use a lower cadence and higher gear, otherwise you waste energy turning the cranks faster than they need to. I think the problem with your test is that Alex was going far too easily, as his 200 watts was only getting a heart rate of 100-108 bpm. He is obviously far fitter than me. The test would only really be valid if it were in the 130-160 bpm zone, as this would show some useful results. At that sort of effort then you may be able to say that lower gears were more helpful. I use 52/36 11/28 around Hampshire southern UK and find that perfectly sufficient (hilly county, but no big long hills). I bought an 11/32 for riding up Mt Ventoux in France which was helpful, but when I came back to UK I found the the 32 very much superfluous, and had annoying gaps in the gearing jumps (11 speed). I very quickly changed back to 11/28 which was much better. Choose your correct gearing for your local conditions and your fitness would be my recommendation.

[@jrokyta4340]

In a hilly area like Krušné Hory, where I live, 11-34 is in my opinion almost essential. I´m so used to it, that I don´t even notice the gaps between gears. The main advantage is, that you can go fast with large chainring and smallest cog and then, when you approach a steep hill, you still have the opportunity to shift to the largest cog and smaller chainring, enabling you to conquer it with much less effort, than if you´d have to grind it on 28t, out of the saddle, with aero penalty and weight suboptimally distributed more forward.

[@Melvpedals]

Yes, I’ve been training this too, light gear, high cadence, no stress on legs and I can conquer the climb better. Then still have the energy to complete long flats.

10 speed 12-28 cassette, with a compact double for me. My old 10 speed Ultegra short cage won’t take anything bigger, but then I rarely go on huge climbs and I’m happier on cadences lower than 80rpm anyway

[@Kiwisail]

When I got my Wilier Rave SLR that had Ultegra 11-30 & 50-34 I changed it to 11-34 and used a GRX 48-31 chainring. Makes hills so much easier and I spend way more time in the 34 cog than I do in the 11 cog...my legs thank me for it!

[@JoshuaTootell]

The best gearing is user dependent. Pick the gearing that works best for YOU. With the new 11-30 cassette on my 12 speed Dura Ace, I think I'm okay with the stock 52/36. My last bike had 50/34 with 11-28.

[@RobBelanger]

You probably don’t see a big difference between the easiest gears on your new vs your old setup. The new setup should be just slightly easier (36/30 < 34/28).

[@chrisdelaplante5515]

Depends where you are living, if it's flat a 25 at rear is ok, but if you live in mountains a 32 or even more can be usefull !

[@astonmartinastonmart]

Was running easier gears forty years ago and still using them. You can get round the big jumps between gears by using a ‘Frankenstein’ cassette - single tooth jumps from 11 to 19 teeth then three more sprockets to 32 teeth

[@gseblonka]

Finally road biking is catching onto what mtb has been doing for a good while .

[@JasonMatthewCrabtree]

What's interesting is I rarely hear what I feel is the important part of these conversations on gearing (or even brake type) is where do you typically ride? I live in an area that's very hilly so it's nice to have a really wide range because I have lots of opportunities where there is a somewhat decent climb and it's nice to be able to keep the Cadence up, as well as a lot of descents where I'm pedaling in highest gear. If I lived somewhere flattered I would much prefer a much tighter cassette to have more control over the Cadence. And if I lived somewhere like Florida I would like to have a one by on my road bike.

[@chrisduffill5248]

Interesting , I agree with your synopsis, my road bike is over 20 years old and the gear ratios are not good for steep hills. I also have a hybrid which is much newer and a darn sight heavier , but find it easier going up steep climbs as I have a better range of gears… so will look at getting a new group set that gives me a better range and open up the rides I can do on my road bike…. . As the winter is on its way , a project for the new year I think….

[@denverspin]

👍 do it before the bike shops get busy. The mechanics appreciate that 😉

[@elnytango]

I get the point of using easier gearing for climbing steeper gradients. But I don’t get the point of this particular test from the point of which gearing (if any) will be faster while maintaining same power output. I am not sure if anyone commented on this yet, but from pure physics (science) point of view the results must be equal. They had to be equal, there was no much point testing this! This is because an object (cyclist with his bike) will increase its potential energy to same amount in both cases when moved from point A to point B. This is because the starting and finishing points are the same! Thus, the WORK required to lift an object to same vertical distance is equal in both cases in this test. It is irrelevant how steep the actual climb (you might as well move perfectly vertically to same amount of height to produce same amount of WORK). Since Alex was cycling at exactly same POWER, the TIME = WORK / POWER will be the same in both cases. Then allow a bit for discrepancies for differences between cassette weights (which would be negligent compared to overall weight of the object), wind, etc. and you will get that 1 second discrepancy. I must say Alex was really good at keeping his power output so consistent! But from the point of finding out which setup would be faster, given the agreed conditions of maintaining same POWER, the test was pointless.

It allows me to always have the right cadence.

[@gregor9921]

Welp, another video Dylan Johnson has made before, short answer, the cadence you're the most comfortable with is the fastest, also for training gains

[@sventice]

I was a bit surprised that there was basically no difference in your test. My own experience is that bigger cassettes are way easier on the body, but also a bit slower. The big advantage of lower gearing for me (and probably a lot of others) is that lower gears help prevent injury on steep hills or very long climbs. I switched to a smaller chainring a couple of years ago for that reason, and while a 30/46 is a bit slower, it's been a big help in keeping me from hurting myself.

[@gcntech]

Do you struggle to find that you can put the power down with the bigger gears? We know that lots of pros are now doing high cadence training.

[@scotthamilton1054]

I think everyone should consider their own unique physiology .. my ftp tends to be higher with bigger gear ratios… also varying the technique up a climb can be a a lifesaver.. seated high cadence low gear interwoven with standing efforts at a higher gear will shift the climbing burden between both of your energy systems. Most will toggle the gearing at the rear cassette to hit this technique. I discovered doing this between front rings instead and it unleashes so much leverage. It’s so effective and it’s my own thing I found through experimenting by trying everything. My buddies can’t believe how well that works but they are afraid to try it. It can cause havoc on the lower back so this technique should be metered if one has lower back issues like myself

[@xuchenglin6256]

This is true. Cyclist comes in all ability/fitness levels a lot of commenters are beginners even though they might have ride for decades. They are just not "fit enough" to crank it up. Scientific research has shown that the metabolism cost is lowest at lower RPMs like 60s, so that's supposed to be the most efficient RPM mechanical/metabolically. That could explain why your FTP is higher. Given the fact that your cardio system always maxed out if you do it right, whichever approach that has a higher efficiency results in a higher number. However this efficiency in the research papers doesn't concern how long you can hold it. My guess is though the efficiency is higher, the time to fatigue could be shorter than the other approach. I bet you did your FTP test using 15 or 20 minutes protocol, but if you actually try to ride your FTP for 1 hour or do a 1 hour FTP (I know nobody is doing it), your preference could shift. That could also be true if you try to ride a 1.5-2 hour huge climb continuously and try to get a PB. Your body could automatically shift before you even notice it. For a lot of people just to be able to go non-stop on a climb already needs a TT-ish effort, that's why they swear easier gears. But if you are fitter, actually for recreational climb you got a lot of options just like the flat. The thing is for fitter riders unless you are doing TT or TRI no cycling effort is something like that flatline. You are in the surge-recover-surge-recover loop, as long as you can recover, the higher the efficiency the better. I myself actually find the similar so I did some research into it. You are not alone and not a weirdo. Simply put most riders are just not fit enough to experience the alternative.

i personally find a lower cadence easier on climbs with my preference being around 50 to 60 rpm. i find that prolonged efforts at a high cadence will give my cramp - no matter how much i prepare, hydrate, warm up, massage, cast a magic spell and whatever else to stop that. i have noticed though that when racing on rouvy on hilly routes i seem to be able to pass people quite easily and then maybe give myself a 20 second respite by moving to an easier gear. As for the angliru. i have only ever done it on rouvy. first time was a few months ago when i crawled up at around 25 to 30 rpm (due to snapping the inner chain ring and the best option being 52 - 28). Did the route again for my 50th a few weeks ago a few times when it was much easier.

Good stuff boys

[@kovie9162]

I'm actually going in the opposite direction. My road bike is 10 speed which I might upgrade to 11, 12 or even 13 someday but not anytime soon. I've been riding a 12-25 for years with a 30-42-53 triple up front, and it's worked well for me other than the steepest of climbs, but I found that I missed having an 18. 17 was sometimes too hard and 19 too easy. So I got a 12-23 but have yet to use it. If I ever did move up to more speeds I'd probably keep the 12-23 and use the extra cogs to add a 28 and 34 if I go for a 12 speed and a 26, 30 and 34 for a 13 speed. I'm never getting rid of the triple as it's not that much more weight and while I don't use the 30 that often I use it often enough to be worth it. Combined with a 28 or 34 cog and I'd be set. And, yes, I prefer to always be at higher cadences whether on the flats of climbing. Feels much better and I find that I'm much more efficient that way.

[@oneninetyseven]

I get the reasoning behind it, but what ismt being taken into consideration is how one's body functions. Everybody has their one "natural" cadence, so trying to force a higher cadence might not be as efficient. Also, as they mentioned, the jumps between gears is not as smooth. A rider could easily be forced to use a cadence they wouldn't prefer to use. It should also be kept in mind what a rider's cardio ability is. Lastly, a rider needs to test out which gear set up works best for specific locations. When I was traveling to HK multiple times a year I tried various gear set ups. Eventually, I found a 50/34 with an 11-30 cassette worked best. Next time I go I plan to try a 52/36 with an 11-32 cassette. Reasoning is simple. The top four gears on both set ups in the big ring are almost exactly the same ratio.... ...which goes into riders understanding how gear ratio works. Personally, I've always been a gear masher. My body has no real problems with stressing out the legs. I ride pretty efficiently on a lower cadence. When I suffered a calf strain I did start to use a higher cadence. I was able to do it, but it did not feel natural.

[@SMlFFY85]

I fitted a big cassette on my bike for the hills around me but it felt horrible, I never seemed to have the right gear, so I went back the the smaller one and climbing feels easier and natural now.

If you ride at the same watts on the same bike in the same weather conditions your time will be the same whichever gear you’re in. That’s just how the physics works. The question is what gear allows you to most comfortably and sustainably put out those watts. And for harder climbs what gear allows you to put out the most watts. Most people could do a 20 minute FTP test with higher power at 80-100 rpm than at 50-60 rpm. I rode Ventoux on a hire bike with 32 on the back. I would have liked a 34 or maybe even a 36!
