Bicycle Size Guide
Having a bike that fits properly will have a direct impact on how comfortable you are and the bike's ride qualities. The following fit recommendations are averages across our line of brands and offerings within each category of bike.
Please note that each manufacturer (i.e Cannondale, Giant, and Specialized) will vary slightly on sizing. The following information offers a general rule of thumb when picking out a bike.
