RIGID FORK AXLE-TO-CROWN CALCULATOR

Use this calculator to determine the ideal rigid fork axle-to-crown length needed to maintain the bike’s geometry in a neutral riding position when changing a suspension fork to a rigid fork. If changing from a rigid fork to a suspension fork, try out the Sagged Hardtail Geometry Calculator with the rigid bike as the current bike (left column) and experiment with suspension fork options to approximately match the sagged geometry (right column) with the current rigid geometry.
