ZIPP rear hub ZR1 SL Center Lock | 12x142 mm thru axle | Shimano Road
With the Zipp ZR1 SL, Zipp is launching a lightweight hub set with maximum performance. Based on the proven ZR1 hubs, the SL versions have a lighter hub shell and an optimized bearing system. Originally developed for the premium NSW wheels, the hubs are now also available separately.
The sophisticated freehub system offers 66 engagement points per wheel rotation and ensures quick engagement with six offset pawls organized in two groups of three pawls each. This means that three pawls always engage simultaneously, ensuring direct power transmission from the pedal to the wheel. Another clever detail: when the hub is dismantled, the pawls remain fixed, which makes maintenance much easier.
Equipped with high-quality ceramic hybrid ball bearings, the hubs have extremely low frictional resistance. For easy maintenance, the ZR1 SL hubs come with classic hub flanges for J-bend spokes, which are still the most common spoke shape today. The hubs can be installed on e-road bikes and e-gravel bikes with motors with a torque of up to 60 Nm.
Note: Contrary to the illustrations, the hub is supplied with a Shimano Road freehub body.
