The Moonlander fork has clearance for a 4.7˝ tire on a 100mm rim. It accepts a 135mm hub, but it is non-offset, so you cannot swap your front and rear wheels. Unlike the Pugsley 135 fork, the Moonlander fork is designed for use with a front disc brake adapter so that A) You don’t have to remember to buy two rear adapters, and 2) If your brakes of choice are only available with IS mounts and/ or as a pair, you won’t have to break up a set and find an additional rear brake. Because of this combination of spacing and disc brake adapter type, the Moonlander fork is not compatible with Paul 135mm Whub. It is compatible, however, with any 135mm rear hub and our 135mm front hub.
