The Ceramic bearings come in two sizes, Ceramic 688 for micro 58 hubs and Ceramic 6803C3 for all 17mm hubs. The Ceramic bearings do not fit in the older style hubs that use R4 bearings or 15267 bearings. See the HELP tab on this website under hubsets to determine which front micro or rear cassette hub you have so that you can order the proper bearings to retrofit the hubs.
