fixed gear hub for 72 schwinn continential
I picked up a 72 schwinn continential single speed I would like to convert to fixed gear. The original rims were replaced with 27x1.25 alloy rims at some point.
What do I need for hub size? Is 120mm the standard for road bike rears? Do rims have a standard number of spokes or do I need to count them sometime when I am at home?
