Hi, I think your right on. This LBS is one of very few that understands, has, and respects fixed gear in my area. He did say that Soma lock nuts have a much more deep machined thread, he said they dig into the hub thread and that once they are on they are hard to get off. Oh well.The cheap nut was the one that came with the cheap bike, the LBS had nuts on order. Maybe I should lay off on the skidding till I get a different nut for the side that is still ok.
