The Zipp 61903 ceramic bearing kit is a replacement kit for 30 and 60 rear hubs and the 188 (V9) rear hub. It contains two 61903 bearings with an internal diameter of 17 mm, an external diameter of 30 mm and a width of 7 mm. These are ceramic bearings, to choose when you need to replace the bearings in a compatible rear hub.
Before ordering, check the hub version: the kit is listed for the 188 V9 and the 30 and 60 rear hubs, while the 188 V8 is not listed. Compare the 17 mm internal diameter and 7 mm width with the bearings you are replacing. This helps you avoid ordering an incompatible kit.
