I certainly prefer a reverse threaded lockring, but I've ridden fixed cogs on fw hubs for years with no more than grease on the threads and have never had a problem. I am just careful not to skip stop, but backpressure never loosened one (I don't run a rear brake). I don't bother with a lockring; I wonder if a right hand thread lockring for a rh thread cog makes any difference. (The one time I did use loctite, I made the mistake of using red. When I had to remove it, I put the cog in a vise and used the wheel as a lever: the Dura Ace cog shattered and the force distorted the circumference of the threads -- it made little hills in the threaded part of the hub. Yes, I learned later about heat. My Riv fixies have as low as a 10.3 inch bb height with the tires I favor, and I use track or quill or platform pedals; no problems; again, I'm just careful. But I can see that, from an insurance liability/lawyer attack perspective you would want to be careful. > That the QB is spec'ed with a free/ > free hub (not exactly a commonly available item) seems intentionally > intended to make fixed-gear use more difficult without substantially > modifying the standard part-spec.
