The Arch is the top-choice wheelset among Stan’s own team, which says a lot about what they’ve put into crafting this line. If you ride to push your limits on the most challenging trails, this is the wheelset for you. The new MK4 version includes Stan’s newest innovation in bicycle hubs. Combining top-notch materials with a smart, magnet-driven, engagement system. M-pulse hubs have been reengineered from the ground up to have you rolling smoother, longer.

With Stan’s patented, BST-Asymmetric shape you can expect a top-of-the-line, reliable tubeless seal. While the durable 6069 alloy construction and reinforced spoke bed, combine to create an incredibly durable wheelset that builds confidence with every ride. Built with strength and easy serviceability in mind, the asymmetric rim allows for a single spoke length on both the front and rear wheels. Using traditional J-bend spokes and lacing for proven strength, ride quality, and serviceability for the life of each wheel.


Featuring 17mm axles, made of 7075 aluminum, rolling on long-lasting Enduro-brand bearings, plus a custom grease fill - Stan’s has taken every effort to optimize for low resistance and high durability.

Tubeless-ready with rim tape and Presta valve installed.
