The IRO wheelset does look pretty good but it is $50 more than the foul weather flip flop from nycbikes, so I was wondering if the 120 mm hub could be respaced? I'm starting to feel like a broken record. I see that some say they are respaceable, some say nothing. If you put in a longer axle does that make it respaceable? That's the essence of the question. Could I use an axle from a set of road wheels?
