Zipp ZR1 SL rear hub | 24 Holes | 12x142 mm | CenterLock | Black Zipp

The Zipp ZR1 SL is a lightweight, race-ready hub designed for performance and durability. Inspired by its predecessor, the ZR1 hub, the SL version features a lighter hub shell and bearing system. This hub set is specially designed for our top-level NSW wheels and is now available separately. The ZR1 SL is equipped with carbon steel bearings, with an alternative option for ceramic bearings to lighten the weight. The hub design creates a fast-engaging feel, with 66 engagement points. The six pawls are staggered to operate in two groups of three pawls. At any one time, there are always three pawls engaging. This means that the power from your legs is quickly transferred to your wheels. The design of the rider body keeps the pawls in place during disassembly for easy maintenance. Zipp hubs use J-Bend spokes, the most popular spoke type today. J-Bend spokes are widely available and easier to replace. ZR1 hubs are approved for use with light-assist electric bikes for road or gravel if motor torque does not exceed 60 Nm.
