Wolf Tooth Mountain Front Hub - Straight Pull Centerlock Boost

The Wolf Tooth Mountain Front Hub - Straight Pull Centerlock Boost is the lighter of Wolf Tooth's two mountain front hubs, at a claimed 135g against 192g for the j-bend version. Straight pull spokes and a centerlock rotor interface are what buy that, and both are requirements rather than options: centerlock rotors only, straight pull spokes only, and bladed spokes cannot exceed 2.6mm. It comes in 28 hole only and fits 15x110 Boost forks.

The shell and axle are machined in-house from aerospace-grade 7075-T6 aluminium, running the ENVE INNERDRIVE system inside. That means oversized 42mm steel ratchets and Wolf Tooth's Perfect Preload arrangement, aimed at keeping rolling resistance low and bearing life long. Drive ratchets come in 60T, 80T or 100T, so you can set engagement speed against drag when you spec the wheel.

This is the hub to pick when the build is going light and you are already committed to straight pull spokes. Right to Repair covers it with service kits and replacement parts, alongside a five-year warranty. Available in black, red, blue, orange, ultraviolet purple and gold.
