If you find yourself between the suggested height ranges for two sizes, the ideal approach is to test ride both bikes. At the very least, examine the stack and reach measurements of your current bicycle and compare them to the new model you’re considering to find a comfortable fit.

Remember, not everyone with the same height has the same body shape. If you’ve got longer legs and a shorter torso compared to the average person of your height, you might want to consider going with the smaller size. On the flip side, if you have a longer torso and longer arms, you’re probably better off sizing up.
