I am swapping all the parts from my old bike to a different frame (a 2008). I have a Shimano XTR M952 cartridge BB. The drive side will only thread in about 1/4 way before it becomes very difficult even with the tool. I know the drive side is reverse threaded, and both frames have a 68mm shell. and english thread.
Does this mean I need to take the frame to the LBS to get the threads chased, or am I screwing up something obvious?
