ZR1 Hub stock Yaw - Gears: 11-speed (2x11)In designing an upgraded hubset for our pro proven Firecrest wheel lineup, we turned to our engineering colleagues at SRAMs development center in Schweinfurt, Germany. The result is the ZR1 hubsets for disc wheels. This hubset features better seal design for improved durability and quicker response with 66 points of engagement. Our engineers spent more than two years developing the ZR1. Proving the durability of the hubset included more than 58,500km
