Stan's No Tubes Arch MK4 Rim

The Arch MK4 is designed specifically for trail riding. It balances durability for aggressive terrain with a weight-conscious build, making it efficient enough for long days in the saddle while remaining robust enough for technical descents.

The asymmetric design helps equalize spoke tension between the drive side and the non-drive side of the wheel. This results in a stronger, more reliable wheel build that is better able to handle the stresses of trail riding.

Yes, the Arch MK4 is tubeless-ready. It is designed to make the tubeless conversion process straightforward, allowing you to run lower tire pressures with better traction and a reduced risk of pinch flats.

This rim features a 28 mm internal width. This width is optimized to provide excellent sidewall support for modern trail tires, which improves stability and cornering grip when you are riding on technical or loose terrain.

Yes, the Arch MK4 is designed exclusively for disc brakes. It is not compatible with rim brakes.

The welded joint provides superior structural integrity compared to pinned or sleeved rims. This construction method creates a seamless, stronger connection that enhances the overall durability of the wheel under heavy loads.
