I got my fixed gear on Monday. I bought it off ebay and the guy said he only rode it once. The wheelset is in immaculate condition, except it feels like my hub might be stripped already. Tonight when I was riding it if I put too much pressure on it either way it would skip a little. The hub is threaded for fixed/fixed so I could always use the other side, but if it's going to strip that side too then I'd rather try to get it replaced either by nashbar or the seller. I'm going to take it into the bike shop tomorrow, but I was wondering what you guys think?
