McLain's Bike Service team


Bike sizing is a service we offer with all bike purchases at McLain Cycle & Fitness. We will help you determine the correct bike size, as well as making minor adjustments to the bike to make sure the bike fits your individual frame.

Retül Bike Fitting is a more detailed fitting process that takes advantage of both the latest technology and a highly trained bike fitting specialist to pinpoint and solve individual fitting issues. This process can be helpful for both increasing performance and preventing injury. If you're experiencing pain or discomfort while cycling, or having trouble reaching certain performance benchmarks then you will want to make an appointment with one of our six bike fitting specialists.

Retül bike fitting 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.

Using 3D motion capture technology, the Retül system accurately measures every degree of movement and millimeter of distance, providing you and the fitter with data to support the choices made during the fit for your cycling equipment and personal riding experience.

No matter your level of riding, comfort is crucial for sustaining time spent on the bike.

Man getting a pre-fit physical assessment

Step 1:

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.

Step 2

From there, the fitter will have you get on the bike (either your existing bike or fit bike) to place LED markers on 8 anatomical points of your body which will be tracked by the Retül Vantage Motion Capture system. The Retül Vantage system is used to collect real-time, three-dimensional data from each pedal stroke creating a dynamic fit experience.

Step 3

The real-time data is compiled into the Retül fit software so that the fitter can look at the numbers and dial you into your perfect riding position.

Step 4

Once you and your fitter have dialed in your final bike position, the fitter will create a digital map of your final bike set up using the Retül Zin tool. The bike data and Zin tool measurements are generated into a complete fit report that you can reference at any time after the fit.
