Bike Fitting Service

A bike that is fitted correctly will increase your performance, comfort and enjoyment.

The Retul 3D motion capture bike fitting system uses infra - red LEDS placed on the rider at specific biomechanical reference points. A 3D scanner measures the location of each LED 29 times per second whilst the rider is in motion and under load. The accuracy of each measurement is to within a millimeter.

Typically the measurements are taken over a 15 second period from the side and the front simultaneously and the 435 results are averaged. The resulting data informs the fitter of the most realistic body position and pedal stroke the rider adopts whilst riding for real on the road or trail.

Such detailed data enables us to adjust and tailor your bike to fit your body's optimal biomechanical range. This reduces stress on joints and enables muscles to work with maximum efficiency.

Unlike static fits this dynamic assessment gives feedback as to how the body reacts and interacts in biomechanical motion, resulting in quite simply a better bike fit.

The Sky cycling team, and many pro mountain bike riders and triathletes choose Retul as their bike fit system, including 2011 Ironman World Champion Craig Alexander who improved his bike split by 13 minutes after Retul fitting his latest bike. As Craig recognises ' A good bike fit is the most effective performance upgrade for your ride.'

If you are planning on buying a new bike and what to ensure you get the correct model and size we can perform a bike fit on our fully-adjustable cycle ergometer. Our Lode, mechanically braked ergometer allows us to get you into the ideal position, whilst accurately controlling your workload. We can then use this position to help you identify the ideal ‘stack’ and ‘reach’, and help you identify which brand, model and size of bicycle would be most suited to your ideal position.
