Field notes
The calculator models the cockpit from frame geometry and installed parts rather than treating stack and reach as complete fit information. Its inputs cover frame stack and reach, head-tube angle, total steerer rise, stem length, and stem angle, with a helper for headset cover, spacers, and clamp height. Plans remain on the browser, while JSON and CSV exports provide separate copies of the measurements.
