Fitting Services

In cycling, the individual is the engine, it is important for the mechanical and physiological components to work in harmony with each other to avoid discomfort. Weak or imbalanced muscle groups can force compensation, and mechanical issues such as incorrect saddle position or cleat alignment can cause unnecessary strains. All FOUR levels of fit will target your specific needs to help create a more efficient, pain-free ride.

Why Retül?

1. Bike Fits Must be Dynamic
Using motion capture technology, Retül records the rider's positions in motion, therefore creating the most realistic picture of the rider's actual pedal strokes and body positions when out on the road and trails.

2. Measurements Must be Accurate
Measurements made by traditional tools are subject to human error and therefore can be devastatingly inaccurate.
Slight inaccuracies can drastically change the rider's feel after a ride.
The Retül system is accurate to within less than a millimeter, creating true objective data which can be utilized by the fitter for the perfect biomechanical fit.

3. Biomechanics are Best Assessed in Three-Dimensional Space
Fit data collected in a traditional two-dimensional plane (i.e. video-based systems) is fairly limited because the fitter can only look at one view at a time, and those views stand as independent reference points.
In order to make the best fit recommendations, the fitter must realize that the front and side views are actually interdependent reference points.
In other words, the front and side views must be viewed simultaneously in three dimensions in order to see how all the applicable movements of the body are working together.

Retül uses a 3D motion sensor to simultaneously gather data on multiple angles of the rider.
