68 X 103 or 107
My frame calls for bottom bracket 68 X 103 but almost every site I go to only has 68 X 107. Are they interchangeable or do I need to keep looking?
BB length depends on your crankset, not your frame. The frame may be saying the shortest recommended is 103.
Here's the frame.

So looking at the crankset which say 107 and the frame which says 103 what do you think? Compatible? Not compatible?
Go with what the crank set calls for. No guarantees, but that's your best bet.
