The Feedback Bottom Bracket / Cassette Wrench is compatible with Shimano / SRAM lockrings as well as many external-cup bottom brackets. It's made from cast steel for shop-quality strength, and its 12.5" length provides excellent leverage to break loose high-torque components. The 16 notch bottom bracket tool also works to with similarly designed Centerlock brake rotor lockrings.
Compatible with Shimano / SRAM cassette lockrings and 44 mm diameter 16-notch external bottom bracket cups, such as SRAM, Shimano Hollowtech II, FSA, Race Face, and others.
Ordered by Most Relevant First
This is a great combo tool for cassette lockrings, Shimano bottom brackets and external disc rotor lock rings. Finish quality is excellent and very useful in the garage and for bike travel assembly.
