Bike Fit

Professional Bike Fit

Cyclical Nature Bicycles uses a combination of the Guru Dynamic Fit Unit (DFU) and the Retul 3D Fit System. The only one of its kind in Central Ohio -- to ensure your road, triathalon, or mountain bicycle fits you rather than the other way around.

Fitting Session

Your fitting begins with an interview process which reveals information that will influence the results of your bicycle fit. A physical assessment will address symmetry, flexibility, strength, and current or previous injuries. Your cycling experience, history, and short-and-long term goals will also be considered.

Retul 3D Fit System

The Retul 3D Fit System uses a sensor harness to record and display our fit data while riding. This is combined with video capture of your body position and pedal stroke. An overview of the fit parameters are explained so that you can comtribute to your bicycle fit. A review of the video will help you visualize your pre- and post-fit body positions.

Guru Dynamic Fit Unit (DFU)

The Guru DFU is a motorized, computer-controlled bicycle fitting machine that allows you to try a variety of fit positions in seconds, which helps us dial in the ideal geometry of your new bicycle or existing one down to the millimeter.

Final Measurements and Fit Report

Final Bike Measurements are recorded and included in your fit report along with your pre-fit assessment data and images of your body position for future reference.
