STAN'S arch mk4 rear wheel - 29'' - 12x148 ta - sram xdr - 6-bolt - gray

The Stan's Arch MK4 wheelset is the perfect choice for riders who love pushing their limits across all types of terrain. Whether you're into all-mountain, Downcountry, or trail riding, this wheelset handles climbs, descents, and technical trails with ease. Featuring a 28mm internal width and a lightweight, low-profile design, the Arch MK4 is built to excel on every part of your ride. Its welded seam, reinforced spoke bed, and durable 6069 aluminum construction provide strength and confidence, while Stan's patented Bead Socket Technology ensures a reliable, airtight tubeless seal. The asymmetric BST design improves spoke angle and wheel strength without sacrificing tubeless performance, making inflation and setup effortless. Designed with traditional J-bend spokes for easy serviceability, both front and rear wheels share the same spoke length, simplifying replacements. The M-pulse hubs, CNC-machined by Project321 in Bend, Oregon, feature 6 pawls with Neodymium magnets for quick engagement and minimal resistance during coasting. Built for durability and speed, these hubs engage in just 1.66° of rotation, offering instant power transfer and smooth rolling. Compatible with Shimano Micro Spline, HG, or SRAM XDR freehubs, and available in 6-bolt or Centerlock brake options, the Arch MK4 is tubeless-ready with rim tape installed. This is our most versatile aluminum wheelset, designed for riders seeking reliable performance on every trail, whether climbing, descending, or exploring new terrains.
