Aero Performance Bike Fit for TT, Triathlon and Road Bike

---

It is important to understand the rider history before making changes. Prior or current injuries and asymmetries can significantly affect comfort and power production on the bike and need to be accounted for carefully. This includes saddle selection and cleat adjustment. Positioning on the bike starts with these contact points and getting them wrong will cause problems in other areas. Different sized feet are often not accounted for while shims get thrown about all over the place for leg length discrepancies which are impossible to measure accurately without a calibrated x ray machine and an orthopaedic consultant.

Each process starts with measurements of the client and the bike, using video on a turbo trainer as well as direct measurement. Records are kept to document the initial setup of the bike using standard reference points saddle height, layback, pad stack and reach, extension reach, pad angle, crank length, saddle type. This is then tracked and recorded across the various changes. Areas are highlighted that can be developed to improve performance based on each client's requirements. Over time I have developed a fitting algorithm that has a very high success rate in establishing a powerful and aero position based on a strong biomechanical foundation and incorporating aerodynamic knowledge gained in personal and client experience. Different limits are applied between TT and triathlon positions to account for the  demands of triathlon after getting off the bike. Understanding how a long time trial affects the riders allows adaptation of the process to prioritise comfort to a degree sufficient to enable a strong run off the bike.

Changes are made to position to maintain or establish a stable core from which to generate power while improving drag. Seemingly subtle changes can have a profound effect on comfort, stability and speed. The understanding of how position affects both stability and comfort is critical to this. For example there are crossovers between time trial and triathlon but an Ironman position has some very specific requirements that are not as important in time trials where the race is over when you get off the bike. There is a lot more to a bike fit than saddle, stack and reach adjustment. The bike needs to be adjusted to make it easier for a rider to hold an effective position.

The price of a fit with Aerevolution includes applying the information used to setup the race bike(s) to training bikes as well. The charge is per rider not per bike. Once the rider has been assessed it is helpful to have all bikes set up to the same principles. This provides consistency between training, racing and riding and performance benefits across all bikes as well. The aim is to provide a complete service with unrivalled rider support and access to a great depth of racing knowledge.

Most aero testing or performance bike fit sessions finish when the changes have been made. Aerevolution continues to provide support while the changes are verified, first checking that good power can be produced and that the new position is suitable for the client. Then most importantly race performance is assessed to ensure that a significant improvement has been made. This post-fit support takes the risk out of the process for the client at a very competitive price. 

With new frames starting at £2,000 and rising to £5,000+, disc wheels from £1,000 to £4,000 it has never been more necessary to get a clear handle on where to find value when looking for upgrades. Where used equipment is a good option and where it is noted where to find it. The aim is to provide the best Watts saved per pound spent of any aero improvement service and this is done by making considered adjustments rather than rushing easy changes and measuring race outcomes rather than CdA in artificial environments.

The goal is always to beat previous best results in target races at a price that is affordable and contained.

£450 in advance. This covers the process from initial measurements to verification of race performance. This is much more than a basic bike fit aside from the fact that any fit that is not measuring your drag runs a very high chance of making you slower, meaning you need to pay for another service to improve drag and then hope that works. Aerevolution charges once for the whole aero improvement process through to the verification of a significant improvement.

£950 in advance. This covers the process as described above for bookings with very short notice. Appointments scheduled within 48 hours of contact.

£500 in advance plus £40/hour travel. This covers the process as described above for bookings in your own home or other address that is most convenient for you.

Two levels of coaching and aero focussed support, both including  aero  development advice over the long term,  CdA analysis on a race by race basis*, race strategy advice, training session focus periodised to target races. Access to aero testing sessions at Palmer Park for £200 per session (approx 2 hours).

TT Support Level £100/month with bike fit discounted to £350

TT Support Plus Level including session planning £150/month with bike fit discounted to £300

*Requires build up of comparative data, ideal for club events and out and back traditional courses, less useful on sporting courses ridden infrequently
