The Arch MK4's 28mm internal width and patented lightweight, low-profile design is not afraid to climb, while being an absolute monster on the descents. With a welded seam, reinforced spoke bed, and durable 6069 aluminum construction, these rims give you the confidence to ride everything. When it comes to a consistent and reliable airtight tubeless seal, nothing beats Stan's patented Bead Socket Technology. The Arch MK4 rims feature an asymmetric design with offset spoke holes to improve spoke angle and create a stronger all-around wheel. Unlike most asymmetric rims that suffer from difficult inflation and poor tubeless performance, Stan's BST-Asymmetric design delivers all the advantages of a stronger wheel, with no compromises in tubeless performance.

The M-pulse hub is durable, bombproof and built for speed. This hub with the full complement of Enduro brand bearings. Internals are fully shielded inside the hub, so most dirt can't even reach.
