Boostinator kits allow non-boost wheels to be mounted in Boost spacing frames and forks. When paired with compatible 15x100mm or 12x142mm hubs, Boostinator kits allow existing wheels to be mounted in Boost-standard frames and forks. Boostinator kits consist of a specially-designed axle end-cap and-in the case of rear kits, a precision-machined rotor spacer with a set of six-highstrngth bolts. In keeping with Boost specifications, the disc and cassette are shifted outboard, allowing brakes and derailleurs to function as designed.
