Arch MK3 27.5in Wheel

Boasting a 25% increase in strength and stiffness, the Stans Arch MK3 27.5in Wheel is a solid choice for the extremes of enduro racing and aggressive trail riding. In fact, this wheel is the go-to choice for Stans team of professional enduro racers, so you know it's built to withstand a serious thrashing. Stans achieves an optimal balance of strength, stiffness, and lightweight efficiency with its 6069 alloy rim laced to Sapim Force spokes. Seeing that Stans is a tubeless pioneer, it's no surprise to see the Arch MK3 with Bead Seat Technology (BST) for a proper seal and secure fitment with tubeless set-ups.

The rim's low-profile shape rolls with less resistance and avoids unwanted pinch flats across rocky sections of trail. Its 26-millimeter internal width gives you a correct tire footprint without deforming rubber into a bulbous or bell-like shape. Stans recommends running a tire width in the neighborhood of 2.25 to 2.5-inches for plentiful grip and support. Please note, the front wheel we're offering has a 28-spoke count for a bit of weight savings over the burlier 32-spoke rear. Both wheels enjoy the responsive feel of Neo hubs with a 6-pawl system offering an impressive 10-degree engagement.

I've put it through the wringer

Purchased to replace an old Stans Arch model wheel - the non-Stans hub paws blew out and no replacements available. Not many non-boost wheels available off the shelf these days. This was one of the few I found available quickly. This wheel just works - width works really well with 2.3 width Maxxis tires. Hub engagement isn't breaking any records but is a massive improvement over my previous stock hub/wheel. Wheel has held up over a few hundred miles of technical/rocky trails without any issues.


Do the wheels come with the necessary hardware to mount the brake rotors, or do I need to purchase separately? My rotors are currently connected with rivets. If separate, what size bolts are needed?
