All of our bottom bracket offerings will use an appropriate Conversion Kit specific to the brand and model of crankset to be used. Our Conversion Kits are made to account for crank manufacturers' machining tolerances and ensure they mate perfectly with our precision bearings, extending product life, and reduce the potential for noise.
