New for 2012 we've taken one of our best selling rims and made it even better. The new 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 aggresive trail riding. Quite possibly the best rim for any situation. Inspire confidence in your ride with the ZTR Arch EX. 28 Hole rim.
