What’s the difference between a Bike Sizing and a Bike Fit?

Do you know the difference? Sometimes cyclists think these two services are the same…but they just don’t compare. We’re breaking down the key elements of each.

Many athletes have had a sizing done at their local bike store. A sizing is a quick 15 minute or less adjustment of the saddle height and possibly fore-aft to get the saddle in a reasonable position for either a test ride or the first several weeks of riding. This allows you to get a feel for what needs to be adjusted. 


A fit is a more detailed approach that utilizes measurements and posturing of a rider to optimize saddle positioning, cleat placement, cockpit setup as well as the athlete’s history, goals, and any past history of injury. With this information, a fit specialist uses biomechanical knowledge to properly place a rider in an optimal position.
