Campagnolo® cartridges need their own version of bottom bracket tools. This small tool looks like a freewheel remover, but has a slightly different shape. The BBT-5/FR-11 fits Record®, Chorus®, and Athena® bottom bracket cartridges. It also fit all rear Campagnolo® cassette hub lockrings. The BBT-5/FR-11 has a one-inch hex on the back for use with a wrench or socket. 66 g.
