hub dimension diagram
10/17/13 -- All measurements taken by Karl on a new hub with "rear" rotor offset (can not locate "official" dimensions online anywhere yet). Axle diameter is nominally 10mm (9.8mm actual). Locknut faces have 17.7mm OD. Axle bore is 5.0 to 5.1mm ID. -Karl

Two versions exist; the wheelbuilding dimensions are identical, but the disc rotor mount offset varies. The "rear disc offset" version has 15.3mm from locknut face to rotor mount face. This works with classic Pugsley forks and Mukluk forks from 2011 thru 2013 (Salsa Enabler fork). The "front disc offset" version has 10.4mm from locknut face to rotor mount face. This works with Mukluk forks from 2014 and later (Salsa Bearpaw fork) and the majority of current fatbike forks that still take a 135mm QR hub instead of a thru-axle hub. -Karl
