The VeloFuze 12x142 to 12x148 Boost Hub Adapter Kit converts a non-Boost 12 mm thru-axle rear hub or wheel with 142 mm spacing for use with 148 mm Boost rear spacing. It provides an option for adapting an existing rear wheel rather than replacing the wheel.
This Boost hub adapter uses one 3 mm disc brake rotor spacer and two 3 mm thru-axle spacers. The kit is designed to keep the wheel centered, so re-dishing is not required. The listing notes that the cassette will shift slightly toward the center of the rear triangle while maintaining a functional chainline.
Included are one 3 mm hub rotor adapter, two 3 mm spacers, and six T25 Torx rotor bolts. The adapter is described as a universal fit for most rear hubs. Blue, serviceable thread-locking compound is recommended.
For cyclists, bike shops, and mechanics working with a 12x142 mm rear hub and a 12x148 mm Boost frame, this rear hub conversion kit supplies the specified spacing and rotor-spacing components in one package. Instruction videos are available, and VeloFuze offers installation guidance.
