I've got a spot hub. I've got one of them White industries freewheels. I haven't put anything together yet, but I'm worried about the chainline on my stock. Does anybody run a singlespeed hub? What is your setup? I know I can adjust the Spot hub a little bit, and I know I can space out the BB a bit. Right now I've got an XT crank on a 118. If I went to a front freewheel crank, would that move the granny ring out? Is chainline even that big a deal?
