Stan′s Arch MK4 29 Rear Wheel, 12X148 XD

Arch MK4: our most versatile wheelset.

The Arch MK4 is the wheelset many at Stan’s choose to ride. All-mountain, downcountry, trailduro: if you like pushing limits on climbs, descents and every kind of trail, this is your wheelset. The 28 mm internal width and light, low-profile shape climb happily and descend with confidence, while the welded, reinforced 6069 rim and Stan’s BST-Asymmetric design give a stronger wheel with no compromise in tubeless performance. All Arch MK4 wheels of the same diameter use one J-bend spoke length.

M-pulse hubs, designed with Project321 and CNC-machined in Bend, Oregon, use an innovative neodymium magnetic pawl mechanism for incredibly reliable engagement with virtually no drag. A full set of Enduro bearings and a 17 mm 7075 aluminum axle let M-pulse handle more than twice the force of Stan’s previous hubs, with easily adjustable bearing preload and just 1.66° of engagement.
