[@saurabhsonic]

Great info! As I was watching the video, I immediately wanted to ask you the questions about your setup as it violates almost all of the rules of aerodynamics and drag. But you already pre-answered them in this comment! There should also be a "happiness" coefficient taken into consideration! lol.

[@Cyclingabout]

I'm really looking forward to the time I can next apply these aero principles. It's not conducive to my cross-continental trips, but will be handy when I'm on lots of shorter/faster adventures in Australia next year.

[@antoniocruz8083]

Speed isn't everything but it really depends on where you tour. In Australia surely you need to move fast to cover the long distances. In Europe, if you move too fast you will likely bypass beautiful villages. I forcefully learned the joys of slow touring when I took my wife along, waking up late, long meals and detours to all interesting sites made for the best tour ever. The idea is not to cover as much distance as possible but cover as little as possible without being bored and for that any bag setup will do.

Generally I'm not a frequent tourer/bike packer, but in December I did a 2 week trip with only a saddle bag for gear, and was pretty happy with the overall performance and speed. Enjoyed the video.

[@MTMiser]

Great video and something I've often wondered about. I recently switched from the typical 4-pannier-plus-handlebar-bag-and-dry-bag-on-the-rear-rack touring setup on a converted mountain bike to a bikepacking setup on a road bike. The difference was incredible, but it was as much about the weight drop as it was the aerodynamics. Overall, the bikepacking setup was 40 lbs. (18 kg) lighter. Of course, I had to eliminate a lot of gear that I used to tour with simply because there was nowhere to put it with the bikepacking setup. I found that I didn't miss most of that stuff at all, and the riding was much more enjoyable than before, especially when climbing steep hills. For many years I saw no reason to change my previous setup simply because I was capable of handling that much weight and wind resistance while still enjoying the tour. But as I aged, it became more and more of a struggle. The bikepacking setup lets me fully enjoy touring again.

[@choanlpoto]

Lol nothing to do with setup,more with bad preparation. 18kg of junk 😂

[@MTMiser]

@@choanlpoto One person's junk is another person's treasure. Prep was fine and I had been touring with that much weight for 26 years with no problem, until a tour I did at 68 years old. That prompted me to go light, so I could keep touring into old age.

[@TenFalconsMusic]

The bikepacking set-up is a quantum leap forward for efficiency and a more comfortable ride. Like you, I had to lose a few litres of space, but I didn't need that kitchen sink anyway.

[@timdixo]

A beautifully put together piece with some great take homes,you’re clearly something of a guru. Also would love to know the drag variances with subtle changes in hand/bar position eg 42cm vs 46cm gravel bars,hands on hoods with optimised elbow flexion vs a standard hoods position etc etc. Most studies I’ve seen gloss over this aspect simply testing the tops/hoods/drops

[@mennodekhuyzen7523]

I did two 6 months trips on a recumbent 20.000 km and I loved it. With sometimes a lot of luggage my recumbent was made for these trips! Next trip will be bikepacking the GDMBR on a “normal” bike. An other trip will be on a Brompton. There are a lot of reasons to use a different bicycle for different trips. Interesting video, thanks!

[@Or5mr]

Really nice and informative video, as always quality. I'm even more happy now that I've chosen to go full bike bags and no panniers in my set up, headwinds can be an ordeal.

[@JonPrevost]

"Pick a path and get in-line." hehehehe. I very much enjoy that the most pedal efficient is the lazy recumbent, briefly mentioned at the end. Less efficient when you realize how difficult it is to keep going straight at low speeds because the moment of inertia from the tire contact patch is so much lower... but yeah, and the fact that for touring it's really unsafe not being able to see traffic from such a low position. Great content and very enjoyable to see you working with the science to give some gentle insight on the aero advantages that most of us could benefit from. Thank you.

[@123cp8]

I love your data-driven interpretation!!! This is just good science! Kudos, dude!!!

[@Cyclingabout]

[@MoyMacGill]

Love the science in your explanation of your topics

[@jerrymiller276]

So we've finally proved what everyone already knew. The more comfortable you are on a bike, the slower you are.

[@jerrymiller276]

P.S. I ride a tadpole trike and tow a trailer when touring, so that makes me infinitely slow. Especially when I stop to take a nap midday without even getting out of the seat.

[@Cyclingabout]

Not necessarily true. I'm just as comfortable riding my road and gravel bikes long distances as I am riding my touring bike. And those bikes allow for a lower CdA. Plus, half of this video was about luggage and clothing, two things that won't change your comfort levels!

[@AlveHenricson]

Wrong. What we learned is that we should use velomobiles for fast travelling.

[@jerrymiller276]

@@Cyclingabout You are speaking of comfort relative to bikes in general. Trikes are among the most comfortable pedal machines out there. But I can wear clothing that is comfortable anywhere on or off the trike and doesn't look dorky. And I don't need a maxi-pad to protect my delicate parts, always more comfortable and no numbness at the end of a century ride. I'm an older guy and tend to wait out the heat of the day napping in a shady spot. I can do it sitting on the seat of my trike. It helps if I have something to prop my feet up on, but is not really necessary. If you don't think that is more comfortable, try taking a nap on your bike. Comfortable but slow. Slower but most comfortable. But you missed the whole point: the comment was a joke, not meant to be takens seriously by any means. I'm slow anyway, no matter what I ride. But I don't really care since I'm a tourist, not a racer, and don't set daily distance goals. I like to do six hours of turning the pedals and start to look for a place to camp for the night. I'm retired so I don't care how long it takes me. I can stop and smell and photograph the flowers, see the sights, like Mammoth Cave, Bryce Canyon, The Cosmosphere in Hutchinson, KS, etc without changing my clothes or walking funny. The cost is speed while riding, a price I'm quite willing to pay.

[@jerrymiller276]

@@AlveHenricson Can't argue with that! But the damn things are costly. I'd have to give up other toys to be able to justify the price. Plus, I already climb slowly and climbing performance is generally more important than overall speed because most of the flat places aren't truly flat and speed on the downhills cannot make up for time lost climbing. If I lived in one of the prarie states, I'd be more likely to consider it because the mountains there are made of wind. But I live in NC where the hills and mountains are made of the more traditional rock and dirt and you are going either up or down, seldom cruising on the flat, except at the coast, five hours away from me by car. But I get you and would love to be able to justify having one. I'd still choose the trike for touring, though.

[@mikechajecki7323]

Great information, thank you!

[@LucaMatteis]

Great information as always. As a relatively slow tourer myself I think I favor comfort rather than efficiency. Would be interesting to see how a more upright position for long rides impacts on performance since an open chest can definitely improve breathing.

[@Cyclingabout]

Comfort and efficiency are not mutually exclusive! More fitted clothes, as opposed to baggy clothes, are a perfect example of this. As are more in-line bags on your bike (provided you do not need the capacity). I'm not so sure there are big differences in terms of lung capacity whether you use a narrow drop bar or wide flat bar. I haven't yet looked through the scientific literature, so if you've seen something interesting - link it through!

[@cwr8618]

I agree on the curiosity. Over time your neck and back and shoulders hurt trying to be aerodynamic

[@petesig93]

A more upright position is actually a better thing for faster hill-climbing. Sitting up frees your quads to spin the legs easier. I ride up a local steep climb about 2kmh faster by sitting more upright, and even just steering with one hand.

[@LordFata]

Great content as always! Never thought about fenders having possible positive effect on drag. Your video front and back panniers helped me a lot to plan for Norway this August. 9 days of riding 170 km each was enough for aerodynamics to matter a lot. However as I had to run 2 bulky rolls on the fork for tent and sleeping mat, which are about as aerodynamic as 2 front panniers, I went for back panniers instead of saddle bag. With mostly cold days and terrible rain, I was so glad to be able to remove the bags quickly and had some extra space for comfort food. Well worth the slightly worse aerodynamics. Noticable drag on decents compared to my unloaded bike. Barely had to brake, which during touring is a win in my book.

Interesting video, lots of good information. I would be curious to see if anyone could make a lightweight rigid pannier set that would also be more aero. Some motorcycle panniers are more aero than others and you can notice a handling and mpg difference with them.

[@russellmoore1533]

When I was into Audax and cycle touring some years ago I made myself a set of aero panniers that included two smaller aero front panniers, two larger aero rear panniers, a rear aero rack top bag and a front aero handle bar bag with a concealed aero bar that could be raised up so I could go into a tuck position. Depending on the trip/s I used some all all of them at any one time. They are were made out of a lightweight rip stop canvas with plastic sheeting inserted into them to keep their teardrop shape. In fact I still have them and anyone is welcome to have them for free.

[@patricj951]

This is indeed a very interesting topic! Here I also would like to see an aerodynamic front windshield like motorbikes have. I think it would contribute to even less drag. Regarding the relation between air and rolling resistance this is dependent on as well speed and kind of tires and used air pressure in the tires. Air resistance being 90% of the total resistance at 30km/h is surely valid with racing tires. With wider tires the rolling resistance is a bigger part of the total resistance. If we go to the extreme: with low pressure fatbike tires the rolling resistance will probably be the major resistance at 30km/h.

Damn your giving away my secrets... Some of the best aero gains I've experience was to strap a big round and smooth stuffsack to the underside of the front of my aerobars. My theory is that it worked a bit like a windshield deflecting air up and around my torso, creating a bubble to hide behind. That aerogain from a saddlebag to fill the lowpressure behind the rider is very intresting.

[@markjohnson9495]

I can see why the inline style frame bags, narrow and long rear bags, and slim front bags help keep everything in the plane of your body. You just have to economize on what you carry, and more importantly what you don't carry. Lots of panniers is like having lots of parachutes to drag on you.

I just purchased a rear seat bag and plan to get a triangle bag, top tube bag and possibly a handlebar bag. I think an aerodynamic handlebar bag is the hardest thing to find. I have toyed with the idea of aerobars and a bag like the seat bag up front. I think this might be more aero than none bagged riding but giving me more storage at the same time. Fenders have also crossed my mind for the rainy days and wet roads just to keep things a little cleaner. Running a litespeed gravel drop bar with GRX 800 groupo and 650b wheels with 47c refuse tires. It works great as a road/gravel bike with no gear although the treadless tires aren't the greatest in some more slippery conditions when off road.

While frontal area is a shortcoming when riding into head wind, more frontal area "from the rear" may be a benefit when riding with tail wind, including flappy rain jacket, and the more so the greater the wind speed. You might be struggling to push 18-20 km/h on flat ground with rear panniers with a strong head wind, that same wind force as a tail wind can help you easily maintain 30 km/h + for hours. That means you get to your destination roughly much faster... So the amazing trick to achieve these results is to ride in a direction where the wind is blowing in the same direction you are travelling. No need for carbon and titanium and shielded everything... just (a lot of ) patience.

​@D R They have very thin rims with carbon aero rims on time trials. I think FCA is working against bicycle technology last 10 years. But you're right, with that 7,5kg downlimit, you can easily add a fender and still be 7,5kg.

@D R Another reason might be because you don't need aero, but lightness in races. aero is more required if you travel more than an hour with your bike. Not for the speed but for efficiency I'd get it, You travel 100km, get tired for 90km, in a way of speaking..10km free ride without effort.

Great video!! Thank you! You are clearly into going deep down the rabbit hole. You should read "the sacred cow".

Great! The time you save by getting there faster might just make up for the time wasted unpacking and repacking everything from a dozen little stuff sacks.
