Understanding road bike fit aerodynamics - how to get more aero!

PH587141 • Oct 23, 2023

Chris Hall came to visit us at AeroCoach HQ in order to improve his bike fit on the road bike, specifically focusing on aerodynamics for road bike time trials. 

In this video Dr Xavier Disley runs through what to look for to improve your road bike fit for aerodynamics: discussing narrow handlebars, turned in levers, torso angle, aero helmets and more, see the video below!

Chris Hall came to visit us at AeroCoach HQ in order to improve his bike fit on his Cervélo road bike, specifically focusing on aerodynamics for road bike time trials. Holding different positions such as in the drops, the breakaway aero position and on the hoods we explored the impact on Chris' body position and how that would relate to his aerodynamic drag. Watch the video to improve your road bike fit for aerodynamics: Xavier and Chris discuss narrow handlebars, turned in levers, torso angle, aero helmets and more!

Ensuring you have the best equipment during high speed track cycling events is extremely important. This data set provides information on the best tubular track tires/tyres for rolling resistance/Crr.

In 2023 there are new regulations for UCI time trial positions, relating to extension reach and shifter height, based on rider height. AeroCoach offer a range of options for our Ascalon extensions to achieve all possible combinations for the three rider height categories. Please see our TT position video below for an overview of the changes, and scroll down for the Ascalon options. PlePlea

Aerobar extensions, whether used on a triathlon/TT bike or using a clip on system on a road bike, come in a wide variety of sizes and shapes. AeroCoach has been testing riders since 2012 and we've noticed a few trends into how you can optimally hold your extensions for aerodynamics as well as comfort. Your body accounts for around 80% of the aerodynamic drag of the bike and rider system. Your optimal stack height, extension reach and elbow width for aerodynamics will be individual and can only be determined by conducting an aero test, but as well as these variables there are differences in how riders hold their hands on extensions, and in this test we explored some general guidelines which you can follow. Don't forget, a lower aerodynamic drag will result in less power required to travel at the same speed, or for the same power will cause an increase in riding speed, when not travelling up steep gradients.

In the UK, having a front light when racing time trials is now obligatory under CTT regulations. Not only this, but also some events are conducted over long periods of time (eg. 24hrs, or multi day ultra endurance rides) and so with front lights being a necessity we explored the impact of front lights on racing aeroydnamics in the wind tunnel.

Using clip on aerobars on a road bike is a great way to improve your aeroydnamics. Your body accounts for around 80% of the aerodynamic drag of the bike and rider system. In this test we explore the impact of holding different positions on a standard drop handlebar, alongside an aerobar position using a set of Ascalon extensions. A lower aerodynamic drag will result in less power required to travel at the same speed, or for the same power will cause an increase in riding speed, when not travelling up steep gradients.
UCI legal and illegal banned road bike aero positions
18 Apr, 2021
The UCI have banned and outlawed some aero positions, such as riding using your forearms as a point of contact. What is the impact of turning the lever hoods inwards or riding with an illegal position with the forearms on aerodynamic drag? What is faster?

Road tubeless liners or inserts are used to provide extra security in the case of a tubeless blowout. In this test we explored their impact on the rolling resistance of a tubeless tyre.
Tubeless sealant and rolling resistance in a Continental GP5000 TL tyre
15 Jun, 2020
How does volume of tubeless sealant affect rolling resistance? We did a test exploring 0-100ml of sealant and the impact on Crr in a Continental GP5000 TL tyre.
