Thanks a ton for this video! Finally a part 2 to the ever going discussion of weight in amateur cycling (part 1 being the uphill weight experiment, of course), again showing one thing: None of us mortals needs a 10 grand bike to go faster. Go out, train, have fun, have a little bit of pain from time to time and you´ll get faster while still having money in the bank. Who would have thought :D

[@rgh622]

Well, thank God I don't need a 10K bike because I refuse to pay that much for anything less than a car. I bought an older used bike, after scouring the local offerings, for $600 and it does everything I need it to. At one time, someone paid a lot of money for it brand new, but it wasn't me. It brings me plenty of enjoyment and I can still appreciate seeing everyone else's new expensive bikes when they buy them.

[@timjurgens1499]

@@tonysadler5290 Well, iti s a thing that revolves around amateur road cyclists. I´ve been a road cyclist when I was younger and worked in a bike shop for quite some time and the discussions I had with people not wanting to buy a bike because another one is 200g lighter... When the rider was 110kg and trained once a week.. And I don´t havea problem with wanting to have a nice bike. It just feels good. I just think that, in amateur cycling, a lot of us should get back to the part where we realize it is a hobby and we do it for fun and do not need to have all the strava kom´s in the area to enjoy ourselves.

Agreed but a lot of things people buy … in fact around 99% of them they don’t actually need. If someone wants to spend 10 grand on a bike or 100 grand on a Tiffany IPhone case, outside of the obvious issue that people are still starving to death, then it’s just their choice.

Some people seem to find it far easier to spend a couple grand than lose a couple kilograms. Near as I can tell. I do neither, I just train as hard as I can and don't worry about it. But then... I'm old...

[@shepshape2585]

Great video Ollie. This is why beginning cyclists can stay motivated pretty easily. If you have some weight to lose and you're just getting started, the improvements will come pretty quickly. It's only when you're at your ideal weight and you've been riding consistently for quite a while that the improvements are much harder to come by. At some point you just have to be happy with where you are and just enjoy riding your bike. Plus, if I were lucky enough to be where you are, would I want to race up that climb, or take it nice and easy and enjoy the view?

[@fVNzO]

I gotta say, it seems like every single comment on KZbin about starting out riding bikes is heavily assuming the beginner to be overweight. I've never been overweight in my life but also saw very rapid gains in speed, very quickly. So idk if it's just the norm to be fat around here but I don't think mega gains are exclusive to them starting out.

[@shepshape2585]

@@fVNzO I get what you’re saying, and of course many people begin cycling as an adult without being overweight. I just think, and I could be wrong, that the majority of adults who get into cycling do so to get ride of some weight and get fit. It may only be ten pounds, or it may be 200. I myself lost 160 through cycling. But in any case, the reason for getting on a bike isn’t really important. The important parts are the benefits that come from it. Better heart health, better mental health, and just a better quality of life.

2 thing strike me about this. First regularly training to specific power indoors has evidently made making these videos much easier! Secondly, the small fairly marginal difference in power (whether from improved rider strength or improved equipment) produces a fair gap on the road. If you're someone who might get dropped regularly this indeed comforting....

[@thekeytoairpower]

So quick math(s)... my system weight is roughly 100kg. So a 1 kg is 1%. I can probably maintain 200 watts on a decent climb so 5 watts is about 2.5%. I would therefore guess that all things being equal I would have to loose 2.5 kg of system weight to equal a five watt increase in power. See I didn't even need to go outside or find a dam or whatever. As a Brit living in the US I am saddened to say that Sir Colin Chapman's "Simplify and add Lightness" looses out to Mr Jeremy Clarkson's "More Power!!!".

[@maartends6051]

Yeah thats about it, if you could maintain more than 5 watt/kg a kg is more beneficial than 5 watts (on a climb). So i would say for long climbs only pro’s and really good amateurs benefit from losing one kg. So if your added watts/ added kg is more than your watt/kg you benefit from it

[@Kim_Miller]

Bear in mind that Chapman was running small capacity highly tuned motors and getting more power means less reliability, while Clarkson says "Why has this V12 only got one turbo charger?" :)

Interesting insights here, top video, cheers Oli 👍🏻

[@andrewcockburn7484]

Ollie was riding at less than 5w/kg so adding 5W would increase his power to weight more than losing 1 kg. It's not surprising he climbed faster with more power. A pro putting out 400W would be putting out nearly 6W/kg so saving a kg will be more important than 5 W to them. It would be more interesting to climb at matched W/kg to see if more power beats less weight.

[@lukaskristanavicius4780]

at matched w/kg Lower weight cyclist will do better. Lower air resistance, plus he will have better v02 max as his body will need less oxygen compared to fat rider as he needs more oxygen for more body tissue

[@augustinhoff9111]

@@lukaskristanavicius4780 That is actually the opposite. Van Aert will almost always need less w/kg to match the speed of pogacar for instance. Could be around 0.5 w/kg less for not so steep gradients. Found it quite right in my case: usually I need the same w/kg than lighter mates only for 10-15% gradients. One key element is that CDA difference in climbing position is not as important as on the flat especially at the speeds most of us are climbing

[@durianriders]

@@lukaskristanavicius4780 at the same wkg a 80kg rider will beat a 70kg rider up most climbs under 9% gradient IF wkg is equal. More weight = more power and more power = more speed. Only the 10% grades does lighter riders at same wkg matter more.

[@ThisIsANameBruh]

@@durianriders wrong, no matter the gradient the heavier rider is always faster assuming the same w/kg. The maths is extremely clear on this. Even at 90% gradient hte heavier rider is faster for the same w/kg

[@rothotborski]

The problem is, heavier riders do have more power but do not have the same power to weight ratio (assuming the same training level) just because their (absolute) VO2max would have to be so much higher and there is no direct relationship between body weight and VO2max. At matched W/kg you would be at same speed if you go exactly vertical - everything which is flatter than vertical more power is faster (assuming everything else is the same). Its simple physics. So going horizontal, weight is meaningless, it is just power versus air and rolling resistance - more is better, as long as you are not a parachute. (Does not relate to running, where body weight is always an issue).

[@playandteach]

Good content, thanks. Also, Ollie, well done on showing off on your Tour des Stations - having Conor show how hard it really is. Ironically, i seem to put on weight over the summer, so I'll have to use the motivation to gain fitness and lose weight on Zwift winter riding again.

[@PietroLiguori]

My first reaction was: guys you’re nuts, it isn’t possible. Then I could finally test it myself by buying a new bike (the Cervélo S5 you featured in the bike vault!): more aero, tubeless tires, more weight (1.5kg heavier!) I did the same steady climb I use to monitor my fitness, around 1.5 km at 5% gradient. Result: exact same avg power (on the same quarq powermeter!) for 1kmh faster avg speed. A gain of around 4% with just increasing aero and rolling efficiency!

[@WalrusRiderEntertainment]

I'm 60kg over my race weight and around 200W less on FTP too. I feel like I am 10% the rider I was in my teens and 20s..

[@patrickmanson282]

Ollie, does it matter how you make the power? Ie what gear? In my head 250w in a easy gear won't give as much speed as 250w in a hard gear. I know it comes down to cadence at the end of the day to generate the power.

[@marshallwade5483]

Hey Ollie, great video, sound data. Have you thought about applying this to eBike battery range? Not the throttled ones but the Hybrids like Wilier is producing.

I’d love to hear your opinion and see testing on this.

Hi GCN. Environmental variables aside. Does the same rider averaging a set wattage up a climb produce the same time or can where you deliver the power on the climb change that. An example being if you rode hard on the steeper sections of a climb but then really easy on the flatter sections and produced an average of 300w and then another ride where you rode easy on the steeper sections and hard on the flatter sections but again produced 300w average, would it be the same time?

[@andrewcockburn7484]

No. Due to the way wind resistance scales it's better to go harder on steep sections where you are moving slower The problem is that you probably won't be to produce the same average power using an uneven pacing strategy.

[@chickenpoodle]

the best analogy is a box of match sticks. you have a set number of matches to burn for the day or for the event, whatever the case it is. when you're riding steady, you light one match, and let it burn before lighting the next one. but if you're doing surges at particular points, each surge may cost you two match sticks instead of just one. cuz as we all know, riding at 250 or 300watts is FAR easier than trying to maintain 400 for a lesser period of time. and so whenever you do a surge, you burn an extra match, and so you can potentially burn all your sticks and be forced to crawl to the finish, which kills your average in the long run.

[@lukaskristanavicius4780]

Great video however I would argue that if you want to improve time you need to improve power and lose weight. for example I started riding at 84kg and 225 Watts, 2 years later I was at 69kg and 330w. Losing weight does not necessarily mean you will lose power. only at those tour de france levels you need to find the ultimate power weight ratio but you need to be at 375w at least to start having that question

Great video, to put into perspective the gains you can make that real matters. For the same time improvement at the same distance, I think it you need to make the same % improvement. 5W over 250W makes 2% of “improvement”; 5W over 400 makes 1,25%

@@stevek8829 well they’ll be as close as you can get to the same CdA if they take the same position and clothes.

Very nice video

[@danc1829]

Great video and definitely agree last winter I did a load of training on my allez winter bike for the Fred Whitton. I set loads of PBs on a bike that was 1.5kg heavier than my TCR just by getting my FTP up from 295 to 312

Just !!!! Depending on your age and experience that’s a bloody great improvement. Chapeau. I would love to have your before number BTW

[@MrBongo1111]

In my situation five kilos would be 25 watts add 25 to ftp and we are looking at 50 watts difference so yeah each kilo matters until the last one so 2.83 vs 3.44 w/kilo . They all matter until they don’t 😃

FTP BLAHHH. BLAHHH Eddie didn’t have our care about a FTP. But great video Ollie as always very scientific. Plus beautiful back drop, only thing that would make it that much more stunning for us mere mortals at home, Upgrade. To 4K let’s us be able to soak it all in.
