picked up an old school set of wheels last weekend, front hub is m900 xtr is that the first gen? rear hub is xt, for 7 speed. the rims are made by campagnolo, which i thought only made road parts? the front wheel is 1x spokes and the rear is 3x. is the 1x inferior, or should I be okay? also the wheels are to be made for singlespeed, right now the rear has a rigged 18t cog but it's spaced a little too inward to match my rigged crank. any way to fix that? like to set it a little bit more outward?
