Retul & Body Geometry Bike Fitting

Retul: Bicycle Fitting for the Digital Age

The Retul motion capture system was developed with professional racers and the best bike fitters in the world and now we bring this revolutionary fitting tool to you! With Retul's 3-dimensional motion capture technology, we can dial in your bike fit to sub-millimeter tolerances. By allowing you to continuously pedal your bike in a trainer, the Retul system lets us see exactly what you're doing as you ride. Retul makes our bike fitting process faster and more precise so you can be riding at your best, sooner! 

When you start your ride do you wonder how long until the numbness or pain sets in?

With our knowledge of biomechanics and kinesiology as it applies to cycling, the Retul system enhances our dynamic bicycle fitting. The harness uses tiny LED lights that flash 42 times per second to send data to the sensor. We have been using Retul now for over seven years and the results are amazing - Ask around. Freddy has fit most of the cyclists in the city.

Cycling and positioning on the bike is simple bio mechanics and we will put you into the right spot to help you evolve as a cyclist. Whatever your passion is - Road, Gravel, Triathlon or Mountain Biking we can make you more comfortable and faster!


From the 8 dots we put on your body in strategic places the data is interpreted by the computer and gives us critical information regarding how you ride. For instance, we can see all of the different knee angles throughout your pedal stroke. And even though the lights may appear to be in one plane, the sensor is able to capture tiny lateral movements, such as a knee wobble, during the pedal stroke that tells us how your body is moving in three dimensions. Retul measure in milimetres not centimetres. Big changes to a well fitted bike are minimal but critical to peak performance and comfort.

And, once we have your final position dialed in your bike, Retul allows us to keep that information in a convenient 3D digital record so we know exactly how to set up any bikes you may purchase in the future. Just as important, with Retul we can quickly and easily compare your past and present bike fits as both your body and your cycling needs change over time.
