WH-7700 wheels and angular contact bearings
Hello, I have some 9 speed black WH-7700 wheels, these are the ones that came with the full Dura Ace group in 1999 or 2000. I have heard the bearings in the them are loose ball and "angular contact." I am therefore a little afraid to just start taking it apart.
I have repacked many hubs before but I have never heard on angular contact bearings, can anyone tell me anything about these? Is it possible for someone like me to just take them apart and repack, anything special to keep in mind? Any help is appreciated.
angular contact bearing is fancy catch-all term that includes cup-and-cone bearings. whether there's anything extra fancy in those hubs, i don't know.
Angular contact refers to bearings that support both radial and thrust (lateral) forces. Cup and cone bearings are included in this class.
