We Take Bike Sizing and Bike Fitting very seriously at Rocktown.

Few things impact the experience of a ride more than how your bike fits you!

Sizing and Fitting are two different things, and of course, not everyone defines Fit the same.

To schedule a fit, please call the shop (540-689-0070) or email chris@rocktownbicycles.com.


How we define "Size" and "Fit":

Sizing is something we do every day at the shop. Bicycles come in more sizes with different fits than ever to accommodate the wide variety of rides and riders. Getting the properly sized bike, and one that suits your needs, is what every customer who purchases a bike at Rocktown gets; it’s the best way to start your new bike experience.

Bike Fit is a far more custom experience. I often hear from customers who say they have been fit, that their experiences are extremely variable. We offer a few levels of Fit, all backed by bio-mechanical data. You get the same experience in a Fit that the riders on Protour teams go through before their season begins. Whether you’re a casual rider or a serious racer, our Fit has you covered and is totally unique to YOU.


The Background:

Chris went to Specialized in 2014 to become certified in Body Geometry Fit; not to just learn Fit, but to grasp the science behind it, too. It’s important to know the ‘why’ as opposed to just going by some numbers because ‘they seem right’. We are fortunate to work with Specialized and the Boulder Center for Sports Medicine, along with Dr. Andy Pruitt, to achieve the best fit possible for every individual

More data is also helpful. Wind tunnel data, tire rolling resistance, and other factors can add up to a significantly faster and more comfortable ride. 

It is extremely satisfying to make someone's experience on the bike better. Whether they are trying to make some small gains or thought they may never cycle without pain again, we're here to help.
