Installing a 68 width into a 73mm shell.... bad?
I have a Surly 1x1 that I just found a crack in my RaceFace cranks. Neat.
I use it as a rainy commuter bike and so figured I would get a Campy alloy crank for it so I could use my pretty full complement of campy rings I already have.
But I have come to realize that nobody makes a british 73mm width ISO taper BB other than Phil and I don't really want to invest $200 on a BB and tools.
So, I assume a 68mm BB would fit but the non-drive side cup would sit recessed into the BB shell by 5mm. Is that the only problem I face?
I know I can install the BB onto a JIS taper, but prefer not to.
I don't want to face the BB to 68mm if possible so as not to a) screw with resale b) intruduce a rust spot since it IS my rain bike.
I already bought the crank so....
