Hi i need some advice i am now in the middle of building my bike up and was testing the shimano external right BB cup and just after 1 full turn it gets really tight but the left BB cup screws in really easy, ive traced the thread on the cup and it looks fine, same for the BB shells any ideas as i dont want to force it or is this normal for a new frame?
