Wolf Tooth Road / Gravel Rear Hub - Straight Pull Centerlock

The Wolf Tooth Road / Gravel Rear Hub - Straight Pull Centerlock covers 12x142 spacing in 24 hole, with the widest freehub choice in the range: XDR, Micro Spline, HG and N3W. That list matters more on a road and gravel hub than anywhere else, since it is the one place SRAM, Shimano and Campagnolo drivetrains all turn up on similar bikes. The shell and axle are machined in-house from aerospace-grade 7075-T6 aluminium.

The ENVE INNERDRIVE internals use oversized 42mm diameter steel ratchets with Wolf Tooth's Perfect Preload, and the drive ratchet is specified at purchase in 40T, 60T, 80T or 100T. The 40T is the low-drag end of that range and the 100T the quickest to pick up, which on a gravel bike is a genuine choice rather than a detail. Centerlock rotors and straight pull spokes are both required, and bladed spokes cannot exceed 2.6mm.

Two fitment notes from Wolf Tooth: the XDR freehub needs a 1.8mm spacer installed behind an XD cassette, which covers SRAM Eagle and T-Type, and the HG freehub has its own spacer requirement, so check the hub spec sheet against your cassette before building.
