My top tips are first to buy a mirror and go side on. Then follow the Hanseatic rule of aero which is "the best way to make something faster is to get rid of it". Remove: Loose clothing Gaps in your body eg behind your head Gaps in the frame As much frontal area as you can The concept of requiring a wind tunnel is a myth. You'll get 98 percent of the way there with a mirror and a turbo, the wind tunnel is only going to be applicable for the small differences and for those riders who are going very fast and or in a velodrome

True words. However most people won't have such en easy time identifying what is better and what's not. I think this is the main reason why the bike industry changed the focus from weight to aero.

Same change can cause no difference at 20k/h some advantage at 30k/h and a game changer at 40! 2: the legs are interesting as they are moving much slower than the bike when coming back on the bottom, and faster than the bike when pushed in the top half circle of the motion!

Interesting stuff. Note: Having hot feet or hands, that 's actually a big deal. There's research to the fact your hands and feet especially are full of circulatory tissues that are responsible for cooling you down. EG - stick your hands or feet out from under the covers when you're hot at night, you'll cool down quickly and back to zzzzzz. Cool feet and hands on the bike likely are helping a lot to cool your whole bod.

I'm no expert... but overcoming friction only makes up part of the energy put into cycling. Even with a completely frictionless system you have to spend a lot of enegry accelerating mass and lifting mass up a height. The idea that 5% reduction of friction equates to 1 day less in a grand tour does not sound right to me. ( it would be much less)

Don't forget - cycling at 15mph with a 10mph headwind is exactly the same as riding 25mph.....so any aero saving is good even though you may not be a strong rider. Another point straight arms on the drops is better than straight arms on the hoods.....I think this was confused with the aero position on the hoods.

For the last 20 years I have always ridden with a Camelbak and no bottles and have noticed how pure roadies look at me as odd. Here are my thoughts: Consider Motor GP racers have a built in hunch in their suits, I can take 2l of water/energy drink mix, tubes, tools etc. My bike is lighter and therefore more controllable. There is no additional wind drag on my down tube, not even bottle holders. How about doing some GCN science to see if I have a point or if I am just out of style.

Great video. A question for #askgcntech , we are told that deeper section wheels makes a great upgrade. Is this true of cheaper wheels or just pro level ones? Presumably cheaper ones have downsides like greater rolling resistance that offsets the aero gains - or is that complete rubbish? Also, is the aero gain linear to depth or does it drop off? Or are very deep section wheels just to unwieldy in the wind? I'm thinking 40 on the front and 56 on the rear might be a sweet spot.

I’m enjoying the bike so far kzitem.infoUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA My only real complaints are the brakes and the pedals. I feel like a bike designed for bigger people should have much larger pedals and more heavy duty brakes. I’ve only gotten two really good rides out of it, minimal downhill action, and the brakes feel like they’re already going out. A larger person has more momentum, so I think this wasn’t thought through very well. Also, I wear size 13-14 wide shoes. My feet cramp up on these pedals that are clearly made for smaller feet. Since I’m not a pro rider (and I don’t think many are who purchase this bike) I don’t think that the straps on the pedal are necessary at all. None of this takes away from the enjoyment I get from riding, however. I’ll just head to a bike shop to improve on a few things.

With the sock isn’t because your leg is also travelling faster than you are so the air speed is much greater passing the leg? GCNs old aero expert has on his website stats on water bottle positions. Drops against hoods is difficult because of holding those positions. It’s not just cyclists that think “this is what we’ve always done” it’s people. The temp thing is obvious, do a workout inside with no fan at room temperature and you will see how it affects you. Most of us have done already. Dan was never my favourite commentator but he’s def lifting his game here. Far more personable and interesting than his usual interviews. He’s in Andorra tax dodging. 😂😂

Talking 1% when it comes to a grand tour is probably a bit ingenuous. Other than the time trials the cyclists aren't running at 100% capacity for anything like the full duration of a days cycling. There's probably less than 1hr a day when the cyclists are running up against their limit. For hour records or time trials the 1% is important but grand tours is more about cycling brains and the support of the team and most importantly the ability to climb.
