The Sachs Freewheel I picked up is too wide for my current axle setup in the rear. The 126mm distance between my rear dropouts is the old standard for road bikes.
Now, I can either re-dish my wheel so that it is slightly off center but able to fit the block of gears, or scrap the whole indexing system. People have said that the strength of the wheel decreases when you re-dish it off center, but I wonder how much. I have a Mavic rear wheel, which is relatively new, with metal (aluminium I imagine) spokes and a shimano hub. I just don’t want to lose my whole wheel and really be screwed. I also don’t want to give up the possibility of having an indexed shifting system on that bike (its an 8-speed index, so a normal 7 speed won’t work).
