Professional Retul Bike Fittings

3-D Dynamic Fit Experience

At E3 Endurance, we have been using the Retul 3-D Dynamic fitting software since 2013.  The Retul system measures riders' body angles while cycling.   Prior to the fitting, we take each cyclist through a short physical assessment to identify strengths & limitations that are crucial to a riders comfort and sustainability.

TEAM FITTINGS

We fit all types of bikes; Road, Mountain, Gravel, Triathlon, Time Trial, even Recumbent.  Before each fitting, we work with the cyclist to understand the needs and goals associated with their bike in order to find the best position for their purpose.
