SIZING GUIDE - Off-Road MTB

When riding off-road it is important to have a slightly smaller frame than you would for normal road riding. This is for 2 reasons, firstly to increase the amount of clearance you have over the crossbar to a minimum of 3 inches and secondly, a smaller frame will handle better over more challenging terrain. This will put you in a slightly more forward position with seat-post height extended.
