Prefer the manufacturer table
Match the model year, wheel size and frame variant. A reused family name does not guarantee unchanged geometry.
RideIn geometry lab
Add your bike geometry
Paste one row per frame size. RideIn checks the table, then stores it only in this browser so you can compare personal, custom and older bikes without creating an account.
Private bike import
Paste a geometry table
Your table stays in this browser. RideIn does not upload or publish it.
Use trustworthy data
Copy measurements from the exact model
Keep units consistent
Enter lengths in millimetres and angles in degrees. Do not mix frame stack with handlebar stack or effective top tube with the sloping tube’s physical length.
Record missing values honestly
Leave a cell blank when the source does not state it. An empty value is more useful than an estimate presented as a measurement.
Keep the original source
Save the source URL or a copy of the manufacturer table with your own records. The browser importer is deliberately private and does not publish community submissions.
