Schedule Your Retül Fit

    Whether you’re a World Tour Professional or a casual weekend rider, comfort is of the utmost importance.


    The correct position keeps your body aligned on the bike, helping to prevent injuries.


    An optimal position not only increases comfort—it maximizes both power and endurance.



Retül Fit is more than just a bike fit—it’s a way to learn about your body, the root cause of your aches and pains, and how a proper fit will help you achieve your cycling goals.



Starting with a pre-fit physical assessment, your fitter will take into account your body’s limitations, previous injuries and pains, and your goals on the bike. From there, we turn to our Vantage Motion Capture System to collect real-time, three-dimensional data from your pedal stroke. This data is then compiled into our system so that your fitter can look at your numbers and dial you into your perfect ride position.


Retül Fit – $350

Retül Fit w/ Medical Assessment – $500
