ZIPP 176 61903 Rear Bearing (x2) #11.2018.061.003

The ZIPP 176/177 61903 bearing kit allows you to replace the bearings on 76/77 (front) and 176/177 (rear) hubs, in both rim and disc versions. Over time and accumulated mileage, the original bearings endure significant stress, which increases friction, noise, and play, compromising the smoothness and precision of your high-performance ZIPP wheels.

This official service kit restores the original performance of your bearings to bring back the responsiveness of your wheelset. Sold as a pair in 6903/61903 size, it is the benchmark solution for preventive maintenance or repair of a ZIPP hub with play or reduced rolling smoothness.
