My Soma Double Cross DC accepts both disc & rim brakes, It also accepts both 130mm and 135mm spacing. The rear drop-outs are 132.5mm and the frame is steel.
Currently the bike has 130mm Shimano 105 road hubs and canti brakes.
I want to build a new wheel set that has 135 spacing and will later accept a disc brake. For now, I'll continue to use the canti brakes. The rims will have machined sidwalls for rim brakes.
What 135mm disc brake hub for my CX bike? I would like to keep the cost of the hub moderate, in the $100 to $150 range.
