PERFECT BOTTOM BRACKET SHELLS, EVERY TIME .1.37″ x 24 TPI Taps. 45mm Facer. Two-Piece Piloted System.

Product Introduction

“The cornerstone of any professional frame prep station — a piloted tapping and facing system that restores damaged threads, squares off deformed shell faces, and ensures bottom bracket bearings sit perfectly concentric.

Most bottom bracket issues — creaking, binding, short bearing life — trace back to poor shell preparation. This system solves that with a precision-machined two-piece handle that engages through the shell, keeping both sides perfectly aligned. After tapping, the taps themselves become guides that keep the facing cutter dead-square with the bottom bracket axis — delivering results that cheap standalone taps simply cannot match.

It includes English-threaded taps (1.370″ x 24 TPI) and a 45mm facing cutter. For Italian, T47, or oversized shells, optional taps and facers are available. Whether you’re restoring a vintage frame, building up a new race bike, or maintaining a fleet, this tool eliminates the creaks, premature wear, and misalignment that plague poorly prepared frames.”

Product Features

🎯 Piloted Two-Piece Handle System
“Precision-manufactured handle engages through the bottom bracket shell, ensuring both sides are aligned with the shell and each other. No more guesswork, no more crooked threads.”
