CAMPAGNOLO CASSETTE LOCKRING AND BOTTOM BRACKET TOOL PARK TOOL BBT-5/FR-11

The Park Tool BBT-5/FR-11 is the Campagnolo cassette lockring and bottom bracket tool: a single tool with a 12-spline profile that fits both Campagnolo cassette lockrings and Campagnolo cartridge bottom brackets. It is a basic tool for anyone working on drivetrains from the Vicenza brand.

It is made of heat-treated alloy tool steel, to withstand the high torque needed to break loose tight lockrings and cups. The 12-spline profile has an outside diameter of approximately 22.8 mm. At the base there is a 1" hex that is used with an adjustable wrench, a socket or a bench vise: to remove the cassette, hold the sprockets with a chain whip and unscrew the lockring with the wrench.

Where to use the Campagnolo cassette lockring tool

• Removing and installing the lockrings of all Campagnolo cassettes
• Campagnolo cartridge bottom brackets, including Chorus and Centaur
• Cassette replacement, gearing changes and freehub body cleaning
• Bottom bracket service on Campagnolo road bikes

Why choose Park Tool BBT-5/FR-11

Note: every remover profile is different, and the BBT-5/FR-11 is not interchangeable with the Park Tool FR-1.3, FR-5.2 or FR-7 tools intended for other systems. For anyone working on Campagnolo groupsets, the Park Tool BBT-5/FR-11 Campagnolo cassette lockring and bottom bracket tool is a simple, essential tool.
