Thanks for the input guys! ...really appreciate it. I have been wrestling with this SS project over
I managed to respaced the hub relative to the axle (moved a 4mm spacer over to the non-drive side).
The rim is not off center by too much. Do you think i can get away with this without redishing the
rim? Anyways, the chainline difference is now around 1.5-3mm. Do you think this is going to cause
trouble? I will be using a 1/2 by 1/8 BMX chain... The front chainring is a 42t 7speed campy victory
ring and the rear is a 16t Shimano freewheel....
