Unior Bottom Bracket Shell Facing tool

UNIOR Bottom Bracket Shell Facing Tool | Precision Frame Preparation

Achieve the pinnacle of drivetrain performance and silence persistent creaks with the UNIOR Bottom Bracket Shell Facing Tool. An essential instrument for professional bicycle workshops, frame builders, and meticulous home mechanics, this tool is engineered to solve one of the most common sources of bicycle noise and premature component wear: an imperfectly prepared bottom bracket shell. By precisely milling the outer faces of the shell, it ensures they are perfectly parallel and perpendicular to the threads, creating the ideal foundation for any threaded bottom bracket installation.

The primary benefit of a properly faced bottom bracket shell is the elimination of creaking. When shell faces are uneven due to manufacturing tolerances or excess paint, the bottom bracket cups cannot sit flush. This misalignment creates uneven pressure on the bearings, leading to annoying noises under pedaling load. This UNIOR facing tool removes a minimal amount of material to create a flawless, flat surface, guaranteeing a solid and silent interface between your frame and bottom bracket.

Beyond noise reduction, this precision preparation significantly enhances performance and extends the life of your components. A perfectly aligned bottom bracket allows the bearings to spin with minimal friction, resulting in a smoother pedal stroke and more efficient power transfer. It prevents the axial and radial loads that cause premature bearing wear, saving you money on frequent replacements and ensuring your high-end components perform as their designers intended. This tool is indispensable when building a new bike, after a frame has been repainted, or when diagnosing a stubborn drivetrain issue.
