They can be double-sided, so long as one side is free. I just got a Bianchi San Jose ss/cx frameset. It's 130mm in the back and probably cannot get to 42mm on the front because of the wider stays. Problem is, most 130mm hubs are made for a 42mm chainline, and I think this one was made for 52mm MTB SS spacing in front. Every wheelset I've come across, from IRO to Paul, uses hubs that either have 42mm chainline or 135mm spacing. I need a wheelset with 130mm spacing and 52mm chainline.
Any wheelset recommendations/ideas? My last resort will be either sending the frame out to be cold-set respaced to 135, or trying a road cassete wheel with cog spacers and one of those nashbar bolt-on skewers. Anyone had experience keeping a ss/fixed wheelin place with those? Thanks in advance!
