-
Morning.
The BB issue is as follows - when I was building it up I found that the threads (which look ok) accepted the BB cup on the drive side, but at some points when it was being screwed in it would just pull out, other times it would hold. After some more investigation I found that when the drive side BB was screwed all the way in and tensioned up it would hold, with some movement and when the rest of the BB was installed it would hold but again with some small movement.
I'm sure one of these would sort it, but I don't think I'd get away with it due to me weight (and awesome power, clearly).
The other thing could be that the BB shell has become slightly oval on the drive side, this would account for the BB cup gripping in some places and then not in others.
I hope thats helpful?
Could you give more details of the problem with frame three's BB shell please and is UK shipping feasible?
