The Shimano BikeFitting XY Positioning Tool is a professional-grade measurement instrument that brings repeatable, high-precision reach and stack data to the workshop. Using the centre of the bottom bracket as a fixed reference point (0,0), the tool calculates X (horizontal) and Y (vertical) coordinates for the saddle and handlebar, giving fitters an accurate, objective record of rider position that can be transferred between bikes with confidence.

Highlights

• Precise XY coordinate measurement: Measures saddle and handlebar positions relative to the bottom bracket centre for objective, repeatable fit data.
• Universal bike compatibility: Suitable for road, mountain, triathlon, gravel, and e-bikes — no wheel removal required.
• High repeatability: Rigid, calibrated measurement system eliminates the human error of tape-measure fitting.
• Position transfer: Enables accurate replication of a rider's position when changing bikes, frames, or components.
• Stand-alone operation: Usable independently of the full BikeFitting.com dynamic fit bike system.
• Integrates with BikeFitting.com platform: Works within the Shimano / BikeFitting.com professional fitting ecosystem for software-assisted fit documentation.

Professional Precision Fitting

Traditional tape measures introduce human error and vary in result across different frame geometries. The Shimano XY Tool replaces guesswork with a rigid, calibrated measurement system anchored to the bottom bracket centre — the universal fixed reference point in bike geometry. Fitters can quickly document saddle height, setback, and handlebar reach and stack, then reproduce those exact coordinates when building up a customer's new bike or dialling in a fit bike.

Versatile, Workshop-Ready Design

Designed to work across all bicycle disciplines without requiring wheel removal, the XY Tool is practical for busy workshop environments. Whether confirming a road bike setup, replicating a triathlon position, or measuring aero pad placement, the tool provides a shared coordinate language that fitters, customers, and frame builders can all reference. The stand-alone configuration means it can serve as an entry point into professional fitting without committing to the full BikeFitting.com position simulator.

Compatibility & Fit

Compatible with all bicycle types and frame standards. Works as a stand-alone measurement tool and integrates with the Shimano / BikeFitting.com dynamic fit bike and software platform. Part number: BFXY01ST (also referenced as E-BFXY01ST). Intended for professional bike fitters and specialist retail workshops.
