BIKE GEOMETRY CALCULATOR
Use the bike geometry calculator to determine the impact of a number of geometry modifications including installation of anglesets, changing wheel sizes, fork travel or offset, and installing an extended crown race or lower headset cup. Check the button at the bottom of the form to view cockpit inputs for optional bike fitting measurements. Note that manufacturers usually round their measurements so the calculated wheelbase, effective top tube, etc. here are shown with decimal places not likely to be shown on the official geometry table.
Want to compare the geometry and fit of multiple bikes? Check out the Multiple Bike Geometry Comparison Tool.
The tool overlays the original bike in red and the modified bike in blue. The bike overlays look best on desktop computers.
