Road Bike Size Calculator

Road bikes have light frames and thinner tires, designed for riding on smooth, paved surfaces such as roads, streets, and paths; some can even handle dirt or gravel roads. Available in many different styles, road bikes are commonly used for racing, touring and commuting. While styles vary, the approach to sizing remains the same, using a rider’s height and leg length to determine the frame size. This calculator will recommend a road bike frame size based on your measurements. If you don’t know your leg length, you will get a range of frame sizes to try out.
