Stans No Tubes Arch EX MTB Rim

The Arch EX is lighter, wider and tougher than the original Arch rim! Once again, Bead Socket Technology construction provides superior tubeless compatibility. The internal arch design provides durability and stiffness, two assets especially important for heavier riders. Although lightweight, the Arch EX can handle aggressive trail riding. Quite possibly the best rim for any situation. Inspire confidence in your ride with the ZTR Arch EX.
