Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Sugino 75 Bottom Bracket

hi,

im taking a stab at installing my first bottom bracket, a sugino 75 (cup and cone style) and i have what's probably a very obvious question to some of you but i gotta ask it anyway, because i don't have a clue:

you know how when you look at the bearings from one side you see mostly casing, and the other, mostly bearings? when i fit spindle, bearings and cups together -- which side of the bearings should face the cup and which side should face the cone?

does this make sense?

thanks much

aaron

Seems the real answer is to dump the retaining cages completely and use the balls loose !

Once greased they are easy to position in the cups as the grease kind of glues them in position so they don't move while you are assembling.

The way I remember this is that the round bearing surface (not the cage) should be in contact with the "cone" of the spindle. If that makes any sense to you.

Basically, follow the "How to maintain..." and you'll be golden.
