The Arch MK4 is the wheelset a lot of us here at Stan’s choose to ride. All-mountain, Downcountry, Trailduro—whatever they’re calling it this week, when you like pushing your limits on climbs, descents, and every kind of trail, this is your wheelset.
Versatile 28mm internal rim width optimized for 2.2-2.5” tires
Light and durable 6069 aluminum with welded joint and reinforced spoke bed
BST-Asymmetric design combines Stan’s legendary easy tubeless inflation with a stronger, more balanced wheel build
M-pulse ultra-low drag magnetic pawl adjustable hubs with 1.66° engagement
Enduro bearings with double-row freehub bearing
Matched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceability
