The Park Tool BBT-5-FR11 Campy Bottom Bracket and Cassette Tool is a dedicated service tool designed to fit Campagnolo-specific bottom bracket cups and cassette lockrings. When performing drivetrain maintenance — whether installing a new bottom bracket, removing an old one, or servicing a Campagnolo cassette — having the correct interface tool is essential. The BBT-5-FR11 delivers a precise fit that minimizes slippage and wear on lockrings and bottom bracket cups, helping protect components and simplifying service work for riders and mechanics alike.

This tool combines two commonly needed service interfaces into a single unit. One side engages Campagnolo bottom bracket cups, giving leverage and stability for removal or installation. The other side matches the pattern used on Campagnolo cassette lockrings, allowing secure engagement when loosening or tightening cassette hardware. This dual-purpose design makes it a versatile and efficient addition to any bike maintenance setup.

Park Tool engineered the BBT-5-FR11 from hardened steel with a corrosion-resistant finish to withstand repeated use in workshop and roadside environments. The machined interface patterns are built to strict tolerances, ensuring that torque is applied directly to the flats of the lockring or bottom bracket cup rather than through worn or rounded surfaces. This precision fit helps preserve component life and reduces the likelihood of tool-induced damage.... Read More
