Freewheel just arrived for my new build and it throws the chainline off to 45mm. This is probably answered elsewhere but if I need to add 3mm to my chainline at the front, does this mean I need to get a bb that's 6mm longer (assuming it's symmetrical). A 107 would have given me 42, so I'm guessing I need 113 now?
Edit
I've re-measured the chainline after I put the wheel into the frame... Turns out I have a 42.5 chainline approx so I won't be touching anything for now.
