External BB bearings...
Ok, I asked this earlier and I didn't get a response, so maybe it can't
be done? My question is can the bearings be replaced in the external BB type cups, like ShimaNO DA? Has anyone done this? It seems they are just press fitted in the cups? Anyone? |

Why aren't these squared off? -- Phil, Squid-in-Training |

External BB bearings...
2 reasons I can think of:
1. Easier to machine the semi-circle than squaring off. 2. Less chance of a stress riser. cel "Phil, Squid-in-Training" wrote in message news:6u1_f.228$ZW3.78@dukeread04...
