Hi I have a three year old Shimano UN91 BB and it doesn't seem to be screwing into my frame
very easily.
I've tried 2 other Shimano BBs and they both go in by hand.
But neither side of this one is easy to put more than a thread or two in by any means.
I'm afraid to put a wrench on it and give it some torque for fear of damaging my frame.
I was wondering if perhaps this could be an Italian thread pitch instead of a standard English.
Does anyone know if Shimano makes Italian threaded stuff?
Also, how do I tell from looking at it if I have an italian or english bottom bracket?
Look forward to your answers...
-cheers
