About & corrections
Position Match is a focused workspace for bicycle fit & cockpit comparison.
A useful result, with the assumptions attached
Compare two cockpits in millimeters, then see the stem and spacer changes needed to reproduce your reference handlebar position.
What this release includes
An interactive local-first tool, editable records where relevant, CSV templates and imports, transparent result tables, optional browser-local saved plans, JSON export and restore, a printable report, and source-linked methodology. A shared backend, verified live catalogs, subscriptions, user accounts, email notifications, and independently audited source coverage are not included.
Report a correction
Use the source-code link in the footer to open an issue with anonymized inputs, the expected result, the actual result, and the method version. Calculation bugs and missing evidence should be reported separately. Source records are not altered because of advertising or sponsorship.
No invented authority
A cockpit calculation cannot guarantee fit, comfort, safe component installation, or handling. Validate the setup with a qualified fitter or mechanic. This tool does not claim certification, professional endorsement, complete source coverage, or market-leading accuracy.
