And here is what Stan’s has to say: Designed with input from NoTubes Enduro World Series teams, the new Arch MK3 is ready to own every trail. Internal width was expanded and a stronger, low-profile shape provides supreme traction, control and reliability.
Bead Socket Technology (BST) secures the bead of the tire creating an air tight seal while allowing the the tire’s sidewall to expand to it’s true, rounder and more effective profile. The result is better traction and lower rolling resistance
WideRight optimized for tires 2.25 – 2.5″ wide
- 26mm internal rim width
