I'm building up a bike and I went to put on a Ultegra SM-BB67000 external BB (BC1.37 - the 68mm one) onto a Cannondale Six13 frame. I've seen other people just hand turn the cups on without much resistance until the very end.
I did this, but ended up with considerable resistance (couldn't turn by hand) with about a 2mm gap on both sides.
I don't have the Park BBT-9 tool yet, but I was concerned about not being able to turn all the way by hand. Is the resistance normal?
