Zipp ZR1 Rear Hub – TA 12x142 – 24H – SRAM/Shimano Road – Center Lock – Black
Zipp developed the ZR1 hubset as an upgraded hubset for its pro-proven Firecrest wheel lineup, working with engineering colleagues at SRAM’s development center in Schweinfurt, Germany. The ZR1 features an improved seal design for increased durability and a quick engagement feel with 66 points of engagement. Development of the ZR1 took more than two years and included more than 58,500 km of test riding as part of 3,222 hours of total testing.
The ZR1 incorporates key technology from Zipp’s Cognition hubs, including a seal design with a large dust cap at the base of the driver body and improved bearing seals for additional protection. The six pawls are offset into two groups of three, with three pawls engaging at any time to provide the specified quick engagement feel. The driver body is designed to keep the pawls in place during disassembly for convenient service. Zipp hubs are designed for J-bend spokes, which are widely available and easier to replace. This version features a 24-hole configuration, SRAM/Shimano Road driver body, and Center Lock disc brake interface.
