The BBT-5 / FR-11 may have a name that sounds like it is straight out of a sci-fi film but it is really a rather simple, yet essential piece of workshop equipment for anyone that owns Campagnolo components. Fitting 12-tooth internally splined Record, Chorus and Athena cartridge bottom brackets and Campagnolo cassette hub lockrings (including 11-speed lockrings) the BBT-5 / FR-11 is a dual purpose piece of kit. The oversized centre hole and thin wall design allows use without removal of cones and locknuts, saving precious riding time. The one-inch base fits the end of the Park SR-1 and FRW-1 tools or simply an adjustable wrench or bench vice.
