Pro Bike Fitting

Our stores offer state-of-the-art pro bike fitting with the Retül system

Whether you are a professional or recreational rider, getting the proper bike fit is an effective and economical way to improve your riding experience. All bodies are different and your riding position should be tailored to suit your biomechanics. By achieving an optimal fit on your bicycle, you in turn maximise comfort, control and efficiency

Traditional tools of the trade, such as tape measure and plumb bobs, do indeed have their uses, however they aren't capable of capturing dynamic measurements whilst the rider is pedalling. That's why we use the state-of-the-art Retül bike fit system.

Using infra-red LEDs placed in specific locations on the rider's body, a 3D scanner is then used to measure each of these LEDs 29 times a second. This allows us to collect rapid streams of information about a rider's position and movement while riding under load. The Retül software is linked up to our computer system, recording this real time biometric data.

During Retül a tracing of body motion is produced and a set of measurements are taken. This allows our trained fitters to make informed, accurate judgements regarding the adjustments each individual rider needs.

Planet X fitters are highly experienced and trained to the highest industry standards. When combined with the unique advantages of the Retül system, this makes for the very highest standard of fit available.

The Retül software saves the data it records for every rider and his / her bicycle. At the end of your Retül session you will receive a report of your final fit data, including body measurements and angles, as well as bike set-up and measurements.
