This dual-purpose tool handles both cassette lockring removal and installation of older Campagnolo cartridge bottom brackets, which makes it useful if you work on bikes from different eras of the Campagnolo lineup. The splines are precision-cut to match Campagnolo's lockring and bottom bracket interface geometry, which gives you a cleaner grip than generic cassette tools that technically fit but leave more room for slippage. If you strip the splines on a cassette lockring because your tool didn't engage fully, you need a new lockring—so the tool fit matters.

The tool works across all Campagnolo cassette lockrings from eight-speed through thirteen-speed drivetrains. For cassette removal, you pair it with a chain whip to hold the cassette stationary while you unthread the lockring. For cassette installation, the tool threads the lockring down by itself—no chain whip needed since the cassette body holds itself in place during tightening. The twenty-four millimeter flats accept a standard wrench or adjustable spanner for applying the torque you need to properly seat the lockring.

For bottom brackets, this tool fits older square-taper cartridge models from Record, Chorus, Centaur, and Athena groupsets manufactured up to two thousand six. These cartridge units thread into the frame and use the same spline interface on the cups that the cassette lockrings use. Campagnolo changed to the Ultra-Torque system after that period, which requires a different tool—the UT-BB130—so verify what bottom bracket standard your frame uses before ordering.... Read More
