All of my single speeds are conversions on either Shimano XT hubs or Hope hubs. I am running wolftooth, Chris King, and Surly cogs. What's the benefits of a single speed freewheel rear hub besides the better bracing angle of the spokes? do they make any that are 135 spaced and disc brake? For the record I'm a buck 80 and I have never destroyed a wheel so I'm not really concerned about the extra bracing angle of the spokes for me anyways. Just wondered if there was any other advantages or disadvantages?
