Maximising time trial, triathlon and road racing performance

---

We hear a lot about marginal gains and while those are important, particularly as many of them are really quite cheap, the first step is to find all the really big gains. Many bike fits are carried out using algorithms with zero understanding of the aerodynamic drag created by the rider. Using an algorithm that measures a response to a position change to determine the new position is not particularly logical when you care about how much drag you're creating. Starting from first principles by developing a position that allows good power production, stability and then minimising drag can be transformative for many riders.

There are details that seem small but are really important and others that have become convention that are not important or even detrimental. The field of bicycle optimisation is a minefield of real data among marketing hype and it can save a lot of money to find out which is which. 

I assess all equipment and can provide advice on how to make the most cost effective improvements to drag with an independent view of the custom parts that are available based on the individual rider's needs.

The same principles apply to road bike fits that apply to time trial and triathlon bikes, riders need a stable position to produce power and then to minimise drag. The complication is that there are fewer fixed points to produce that power against making that core position around the saddle and then hand position more important.Beyond that the air flowing over the rider will respond in the same way to shape changes as on the TT/triathlon bike. An improved shape will be faster.Equipment choices are just as important, the range of rolling resistance for road tyres is larger than for TT/triathlon tyres. The wrong tyre, helmet or clothing can be a huge disadvantage compared to the best available. This is one area that pros can be at a disadvantage to amateurs or club teams as their choice can be limited to only a few sponsor correct options that may be some way from ideal.Road bike position should run in parallel with the TT/trithlon fit where applicable and it is important that the  bikes complement each other properly. I look at the rider as much as the bike and applying similar principles between the bikes within the same price gives benefits across the board.

A big part of aero performance is the speed at which the sport evolves. Methods and equipment selection have to develop year on year to provide the best service and information. Being closely involved with the performance of a number of riders at any time is a learning experience that helps to refine techniques and increase knowledge.

Post fit feedback is essential to demonstrate a successful process while potentially highlighting further improvements to both kit and position. Feedback also helps to highlight riding techniques and strategies that can be beneficial.
