Thanks for all the info everyone. I think I'm gonna slip into the bike co-op periodically over the next few days to check the used bins, and if I find some that seem good I'll pick em up. If if can't find a pair that match (or at least look similar) in good shape I might just try some of the ones on the Niagara site. I just noticed however, that the ones I linked to in the first post are listed in the "MTB Hubs" category. Is this actually significant? Are they going to be different in some way that is going to cause a problem for use on a road bike?
