Are you going as fast as you should be?


Whether you’re racing a sportive, a criterium or an Ironman triathlon, the biggest force slowing you down is your aerodynamic drag.

At 30kph, you will already be spending 75% of your effort just pushing through the air, and at 45kph this will rise to more than 85%.

But before spending your hard-earned money on expensive new equipment such as framesets and wheels, consider whether you are making the most out of what you already have.

The biggest contributor to aerodynamic drag is the rider – around 80% of total drag is generated by you! Luckily, small changes in rider position can reduce drag significantly, with savings of 10-25W easily achievable for most riders.

For example, if initially riding at 40kph, you could expect time savings as per the following table:

Our Service

TT vs Hoods

Hale Dynamics uses structured light 3D scanning to create a full 3D model of the rider that is then post-processed and analysed using computational fluid dynamics (CFD) techniques.

Each 3D scan can be completed in as little as 5 minutes and as such, it is possible to trial multiple different configurations during one analysis session. Small adjustments are made between each scan to assess their effect on aerodynamic drag. By assessing a number of different positions, we can dial-in a position that is both aerodynamic and physiologically effective.

Standard Analysis Session – £250

Hands Up Streamlines

Our standard analysis session takes around 3 hours and consists of 4+ rider scans, with initial feedback provided during the session.

A detailed report is sent via email within five days, providing a comparison of the different positions with time / power savings for your target event.

Sessions are available in Garsington, Oxford – please get in touch for more details.
