The Shimano Bike Fitting Digital Protractor (E-BFPR01) is a precision angle measurement tool designed for professional bike fitters and workshop technicians. Built as part of Shimano's dedicated Bike Fitting System, it delivers accurate, repeatable angle readings to take the guesswork out of positioning — allowing fitters to set seat tube angles, saddle tilt, head tube angles, and steering geometry with confidence.

Highlights

• High-resolution measurement: 0.01° display resolution for precise angle readings during fitting sessions.
• Full 4 × 90° range: Measures across all four quadrants for versatile use on any part of the bike.
• Hold function: Freeze the reading on-screen so you can record measurements without the tool moving.
• Purpose-built for bike fitting: Designed specifically within Shimano's Bike Fitting System for consistent, professional results.
• Compact and portable: Easy to use at the stand or on a fit bike during a live fitting session.

Applications

Use the E-BFPR01 to accurately determine seat tube angle and head tube angle on the frame, set saddle tilt to the rider's preference, and dial in steering angle for optimal handling and comfort. It is an essential tool for any bike shop or fitting studio offering professional fit services.

Compatibility & Fit

The Shimano E-BFPR01 is a standalone measuring tool compatible with any bicycle style — road, mountain, gravel, or e-bike. Requires one 9V battery (not included). Designed for professional workshop and bike fitting use.
