Zipp ZR1SL rear hub, 28 holes, CL, 12x142 mm, SRAM XDR
Zipp's ZR1 SL is a race-ready, lightweight hubset built for performance and durability. The SL version, following in the footsteps of its predecessor, the ZR1 hub, features a lighter hub shell and bearing system. This hub is specifically made for top-tier NSW wheels and is now available separately. The ZR1 SL comes with carbon steel bearings with the option to upgrade to ceramic bearings for reduced weight. The hub design creates a feeling of quick engagement with 66 points of engagement. Six pawls are staggered to work in two groups of three pawls. At any given time, three pawls are engaged. This means the power from your legs is quickly transferred to your wheels. The driver body design keeps the pawls in place for disassembly, making service convenient. Zipp hubs use J-bend spokes, the most popular type of spokes today. J-bend spokes are widely available and easier to replace. ZR1 hubs are approved for use with lightweight e-bikes on the road or gravel, provided the motor torque does not exceed 60 Nm.
