My TA 314 exited this world last night in a vainglorious grind up Brixton Hill. I've taken it all apart and cleaned it up, the cups seem pretty squared off, but I don't really know how they're meant to start. The Axle has some odd pits in the ball races, and seems to have wonkily starting grinding against the mouth of the cups.
Are there any sensible source of replacement cups? How do you tell whether they're too worn.
Failing that, what can I replace the whole BB with?
Is ISO 113mm the best bet?
