Road Bike Size Guide: Get The Right Fit On a Road Bicycle

The below size chart can be used as a very general guide for road bike sizing. Lots of factors of course contribute to finding the right size road bike, but the below chart will be a good start for giving you a general idea of what size road bike you will need. Basically, you'll need to know your height and your inseam length, which are the two most important measurements for determining the proper size road bike. Also, after you purchase a new road bicycle, you may need to make some adjustments here and there for optimal fit. (Adjusting seat height and handlebar angle, as examples.)
