I’m building up a Soma Wolverine with a Gates Carbon Drive and Alfine 11 internal gear hub. The Gates literature indicates that the beltline should be 43.7 mm +/- 1mm.
I am trying to use an old crankset I have on-hand, a Sugino RD2, which has a 45mm chain line when using a 103mm bottom bracket. Obviously this is slightly out of spec with the Gates belt line requirements
My question is, can I use an adjustable Phil Wood bottom bracket to make up the 0.3-1.3 mm difference in beltline? Would it be better to have the bottom bracket built with an offset spindle, which it sounds like Phil Wood can do? Or best to just buy a crankset from Gates?
