In designing an upgraded hubset for our pro-proven Firecrest wheel lineup, we turned to our engineering colleagues at SRAM’s 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 of test riding, part of 3,222 hours of total testing. The ZR1 features key technology from Zipp’s Cognition hubs. The seal design is the same as the Cognition, with a large dust cap at the base of the driver body and better bearing seals for more protection. The bearing size also is the same as the Cognition, although the Cognition uses a premium bearing. The six pawls are offset to work in two groups of three pawls. At any time, there are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement. The driver body is designed so pawls stay in place for disassembly to make service convenient. Zipp hubs are designed to use J-bend spokes, the most popular type of spokes today. J-Bend, widely available, are easier to replace.
