Race Face introduced their Vault hubs on their high-end wheelsets back in 2016. The new hubs represented a clean slate approach rather than an update of previous models. Starting from scratch, Race Face went with larger hub flanges, wider bearing spacing, larger bearings, better seals, and fast, 3° engagement. Since their release, the Vault hubs have received unanimous praise. Until now, though, the Vault hubs were only available as part of a complete wheelset, laced with straight-pull spokes.
Race Face now offers the Vault hub as an aftermarket choice for riders that prefer to build up their own wheelsets. The hubs carry over the same features from those used on the complete wheelsets with one important distinction — they’re designed for classic J-bend spokes.
The hubs come in 28- or 32-hole drillings and Boost, non-Boost, and downhill spacing. Front end cap options include 9×100 QR, 15×100, 15×110, and 20×110. Rear end caps come in 12×142, 12×148, and 12×150/157. In their lightest configuration, the hubs come in at 177g for the front and 305g for the rear. Retail is set at $500 for the set — $175 front and $325 rear.
You’ll need a rim to lace those new hubs to, so Race Face is now selling their carbon Arc 31 rims aftermarket as well. The Arc 31 measure 31mm internally, 37mm externally, and are fairly light at 445g for a 27.5″ rim and 495g for a 29″ rim. Like the hubs, the rims come in either 28- or 32-hole drillings. Retail price for a single rim is $500.
