Echoing some of the comments - a great realistic take on aero. I wouldn’t be convinced of any of the upgrades except when I replace my helmet. I ride tops, hoods and drops like I imagine most riders. And my ‘testing’ shows the more fun I have on the bike the faster I feel - sometimes even a top 10 finish in my head 😆

@ivarbrinkman2195 8 ай бұрын

very sensible sum up...but life is not a wind tunnel. One omission is the adjustment of the seat angle in order accommodate a deeper position. As a rule of thumb: for every cm the stem goes down the saddle can move 0.5 forward. this results in 75-75.5 cm seat post angle -for most riders with reasonable flexibility -both for riding aero on the hoods and in the drops. This will put you back near a horizontal and catlike 'pro' position without out the added strain on the hips, and allow you to hold the position longer.

@Fatbutnotflat Жыл бұрын

If you point the aerobar upward, you have more gain than pointing down . That means if you put more stem spacer , spend more time in aerohood position, you would have more gains than slamming the stem and staying more often just in the hoods. This would be in line with what Peak Torque has mentioned in his videos. Instead of lowering the stack, increse it, but streamline your position.

In fact, the best cost effective aero upgrade for people who haven't optimized their position is a bunch of stems. In order to be comfortable in the aero hoods position, you need a relatively long stem, as is evident from the professional peloton where many use 140mm stems and beyond. You need a number of stems in order to progressively adapt to an optimized position. Back in the day, I was using a Look Ergostem which allowed for freedom of adjustment. This is why integrated cockpits are bad and actually less aero in many cases. For an average rider who hasn't fully optimized his position, a slammed stem is indicative of an incorrect setup, because it removes the margin of adjustment.

@MrChippinator Жыл бұрын

You're right, handlebar and stems make a huge difference. I have a nearly 10 year old frame but "modernized" it with narrower bars and a different stem. To note however, stem length also varies by the frame. For example, I had one bike that felt great with a 120mm whereas my current bike feels great with a 100mm stem. Using the same stem on every bike isn't a good idea either.

People prefer design over performance, that's why integrated sells so well. Also good marketing speech.

@marcdaniels9079 Жыл бұрын

This is way over-simplistic. The human body is extremely complex and all the angles on a bike are inter-related. It’s not just about playing around with stems. The pros ride slammed very long stems because they are prepared to sacrifice all comfort for aero performance and they have someone to give them a 1 hour massage every day. This bears very little relevance to 95% of most cyclists. In fact slammed stems have shown to be distinctly in aero for normal people… look at TT bike position.

People that are box sections are most likely running rim brake bikes and prefer running alloy rims for other reasons such as breaking performance. I bet a speed suit would be a better all round buy compared to deep section wheels at that point. We all seem to think 33-40mm wheels seem to offer the best overall compromise between handling and speed

Reg the aero position with your underarms on the bars you said your triceps burn and hurt. This is because your upper body weight is resting on this underarm and the triceps are taking the weight. In order to get rid of this pain make sure the elbow is on a vertical line with your ear or ahead of it. If behind there will be a cantilever effect hence the burning triceps. To achieve this move your saddle slightly back and your hoods slightly forward on the drop of the bar. You could add a longer stem too. With the upper body load properly supported the cantilever of your head and shoulders should be less and the pain in your triceps alleviated.

Did he keep saying Askium rather than Aksium, or do I need a hearing test? I've had those wheels on my bike since I bought it in 2009. Yeah, I should probably upgrade them...

Very good test. Some relatively fancy aass carbon road wheelset vs. Mavic Aksium (not Askium): 10.6W saved over 216W at 35 km/h. At 30 km/h (assuming a constant CdA) the saving would be roughly 7.8W over 159W, while at 25 km/h it would be about 5.4W over 110W. In no universe are those savings relevant to the average casually riding bloke with a specific FTP of under 3.0 W/kg. This, of course, won't stop middle aged dentists to join the aero malarkey bandwagon and to spend silly amounts of money on aero wheelsets and framesets in order to have the best possible bike to their "L'Etape by Tour de France" long awaited oh-let's-call-it-race. None of those will save them from barely finishing the ride riddled with cramps and back pain, they'll still get dominated by some local dudes riding 10+ year old aluminium bikes on 2x10 mechanical 105, but at least they've earned the bragging rights. Oh, and don't forget having to switch to disc brakes and electronic groupsets to achieve such performance.

I realise that for the general cyclists, it’s less about being aero , than buying new and cool cycling toys and gadgets to have fun. Because let’s be frank, unless you’re some pro cyclist riding in the TDF peloton, cycling is just a hobby for you to spend money on (while trying to stay healthy). You could argue that losing weight, stem slamming is free, but that’s not why you took this up as a hobby for. If it was truly fitness that you were after, you would just go jogging, or ride only on a trainer for maximum efficiency.

3:16 216w for 35kph? There must be some variables not being taken into account, because I promise you 216w is not getting anyone 35kph unless they're on a full tt rig

Hi, 66kg here and very agressif position on my Sl7 with +60mm rims. When i push 216w avg i push easily 35kph on flat routes with 0 wind. So positions and fitness are the best (free) aero upgrades 🙂.

@robbieharrington1950 2 ай бұрын

As a Engineer I can tell you that all this aero bollucks in cycling is a waste of time and money. Your bike may be aerodynamic but YOU are not so buying into the marketing wank about tight lycra clothing helps you being more efficient when it doesn't make any real difference. If you want better efficiency buy components with the lowest amount of friction such as good quality bearings for your hubs for example and keep your bike's moving parts clean and oiled.

Cheapest upgrade is hotwaxing your chain, saves 3 watts and more, shimano dura ace chain saves also some watts compared to others

Simon's a keen chain-waxer already! Does cost a little more than simply optimising your body position though 😉 Here's our guide to waxing chains if you're keen to see more; www.bikeradar.com/advice/workshop/how-to-wax-a-chain/

You made a mistake in testing the helmet in "yaw" conditions. You forgot to turn your head into the wind. This accounts for the reduced cooling effect as well as the drag numbers. Easy mistake to make, many beginners don't square up to the wind.

@@DaM.1 you probably have without noticing, top riders do it naturally. At pro speeds the yaw angles are very slight. You'd need a really strong sidewind to be obvious.
