Crankset won't go into bottom bracket
A friend asked if I could swap his groupset for the new Ultegra group he ordered. We got a new bottom bracket at a shop and they installed it. When I got home to put in the crank, the crank wouldn't go in. I literally had to get a mallet and towel and hammer it in. Can this cause a problem? I tried pushing the crank in but it wouldn't come out the other side all the way. I had to tap it kinda hard to get it in.
