Project 321 Boost / DH / G2 / Super Boost Rear Hub Ceramic Bearing Kit
After logging some serious miles on your ride, you may notice your bearings not performing as they once did. This is normal and to be expected as a bearing experiences lots of wear and tear. These ceramic bearings from Enduro reduce rolling resistance and last even longer than their steel versions if properly maintained!
2 Enduro ceramic bearings
2 Enduro angular contact bearings - 71804, 71903
*angular contact bearings must be installed with the red seal facing outwards
This kit is not for CX1 and G1 hub models
