An all new rim design for Cinema, the Reynolds rim features a large single chamber, double wall profile that is designed for superior strength & stiffness. Every detail was re-approached w/ this rim, from the design, materials, & manufacturing, to create a truly worry-free rim. The super thick sidewalls help to prevent flat spots & warped sidewalls & help stiffen the entire rim. A wide interior center channel & ramped inner walls make for easier tire installation & lock the tire bead securely under the sidewall lip. Optimized spoke angle & thickened nipple seat groove help to keep your spokes tight & your wheels true longer. Tested, approved, & ridden daily by Garrett Reynolds himself.
