I did some analysis and located what I assumed would work and bought a Shimano BBR60. However once I put in, it did not actually match, the size appears to be to brief, and though the chainring aspect is held agency the opposite finish has play as a result of there is a distinction between the diameter of the spindle and the within of the bearing.
Wanting on the hooked up pic you may discover there is a raised polish floor that matches comfortable contained in the bearing on the chainring aspect..and nothing like that on the opposite finish of so I’m utterly baffled, is that this what spindles usually appear like?
1. Anybody know what bb would work with the prevailing crank
2. If I simply exchange the whole lot what’s it I may get that might match?
