The VeloFuze Boost Hub Conversion Kit is a rear-wheel adapter system for converting a non-Boost 12mm thru-axle rear hub with 142mm spacing for use in a modern 148mm Boost frame. It provides an economical way to convert a standard 142mm rear wheel to Boost spacing without changing chainline.
The conversion uses two 6mm spacers installed on the disc side of the hub: a 6mm disc brake rotor spacer and a 6mm hub/axle spacer. This arrangement achieves 148mm Boost spacing. Wheel re-dishing is required as part of the conversion.
The kit includes one 6mm hub/rotor adapter, one 6mm hub spacer, and six T25 Torx rotor bolts. Blue, serviceable thread-locking compound is required during installation, and hub and rotor manufacturer torque specifications should be followed.
VeloFuze designs its Boost hub adapters to be universal and compatible with most hub brands. This product is one of VeloFuze’s Boost Hub Adapter configurations; related products provide additional front and rear conversion options.
