An all new rim design from Cinema, The Reynolds rim features a large single chamber, double wall profile that is designed for superior strength and stiffness. The super thick sidewalls help to prevent flat spots and warped sidewalls and help stiffen the entire rim. A wide interior center channel and ramped inner walls make for easier tire installation and lock the tire bead securely under the sidewall lip. Optimized spoke angle and thickened nipple seat groove help to keep your spokes tight and your wheels true longer. Tested, approved, and ridden daily by Garrett Reynolds himself ###section### Product Specs WHEEL SIZE: 20\" SEAM: Welded ERD: 382.5mm HEIGHT: 21mm WIDTH: 38mm SPOKE HOLES: 36h WEIGHT: 530g
