Professional Retul Bike Fittings
Any Rider
3-D Dynamic Fit Experience
3-D Dynamic Fit Experience
European Professional Riders to Coffee Riders, we fit EVERYONE! Because everyone deserves to be comfortable and reach their destination quicker, with more power (or less), and not be limited by a bad position. How can one reach their potential if their bike position keeps them from it?

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.
Every Bike
3-D Dynamic Fit Experience
Every Bike
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.
