Adapting to a changing world
As much as we love new and improved gear, the rapid proliferation of bicycle-related ‘standards’ can be confusing, frustrating, and costly to consumers.
While incremental, the benefits of the “Boost” 15x110mm front and 12x148mm rear axle standards are clear: better clearance for fatter tires & rims and reduced dish for stiffer, stronger wheels. The big bummer? Taking full advantage requires not only a new frame and fork, but new wheels as well.
In response, we have developed the Boostinator. When paired with compatible 15x100mm or 12x142mm hubs, Boostinator kits allow existing wheels to be mounted in Boost-standard frames and forks. Disc and drivetrain positions are maintained and, thanks to a quick re-dish, spoke bracing angles are improved.
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 high-strength bolts. In keeping with Boost specifications, the disc and cassette are shifted outboard, allowing brakes and derailleurs to function as designed. S
