hey,
fitting a shimano bottom bracket into a brand new pompino frame, the threads in the bottom bracket shell are interrupted by lumps from the chainstay joint, causing the plastic cup to strip as it goes in. Tempted to get a file out but dont want to void any help from On-One.
Any advice from experienced bottom bracket fitters? Is it a case of taking the frame back or filing off the lumps and carrying on?
Thanks,
Ben
