I have a genesis day one frame I was going to run fixed for some commuting and light off-road duties.
I have a philwood sprocket and I was going to run a Miche advanced crankset up front.
The day one has a 68mm BB shell, 135mm rear dropout spacing and a 47.5mm chainline (so I've been told) and the Miche chainline is 42mm with a 107mm BB (so I gather...).
So... with a difference of 5.5 on the chainline I need a BB 11mm bigger, a UN55 118mm in other words?
Is this correct in theory? I've never had to do this before.
