  • It's out. A few minor nicks in the BB shell, but nothing that will be visible when the crankset's installed or will affect fitting the BB.

  • Does it look as though the ineptly applied epoxy (glue, for want of a better word), actually formed a bonding layer between the BB and the cup,
    or,
    was just a very efficient gap filler.
    I'm certain I've seen demoes of (primed) epoxy onto smooth surfaces giving very little adhesion, showing why epoxy needs a mechanical fix, roughened/abraded surface, primed to prevent air entrapment at the interface, (unless applied wet-on-wet).

  • It definitely was bonded, although I think much of the work done by the epoxy in keeping the cup in place was actually due to the rim of cured epoxy squeezed out from the shell which had hardened along the edge of the bearing cup. I'll be using Loctite 609 with primer to keep the new cups in place.
