Stan's NoTubes Arch MK4 Front Wheel

The Arch MK4 is designed for versatility across aggressive riding styles. It is a great choice for All-mountain, Downcountry, and Trailduro riders who need a balance of durability and weight savings.

Yes, it features Stan's signature BST-Asymmetric design, which is engineered specifically for easy tubeless inflation and a secure tire bead seat. It is fully tubeless-ready and uses a standard Presta valve.

No, the Arch MK4 uses traditional J-bend lacing. This makes it much easier to service or replace spokes at any local bike shop compared to wheels that require proprietary straight-pull spokes.

This wheel is compatible with 6-bolt disc brake rotors. It will not work with Centerlock rotors unless you use a specific adapter.

With a 28mm internal rim width, this wheel is optimized for a wide range of modern trail tires. It provides excellent stability for tires typically ranging from 2.2" to 2.5" in width.

The wheel is built with M-pulse ultra-low drag hubs and high-quality Enduro bearings. These are designed for smooth, long-lasting performance, though like any high-performance hub, they will benefit from periodic cleaning and bearing inspection depending on your local trail conditions.
