This is one of the reasons I like Avid brakes so much - their mounting system means that you don't have to face the mount like you do with the older fixed IS systems. Happily most people seem to be adopting a similar (if not identical) system involving post mount adaptors, or just a move to post mounts in general! <BR/><BR/>Chris King headsets use a rubber O ring to fit to the steerer - this is interesting as it's their way of circumventing the US Patent that Cane Creek hold on John Radar's invention of the "aheadset" which uses a tapered wedge to lock things in place. <BR/><BR/>Personally I think the tapered wedge is a lovely neat idea.<BR/><BR/>Thomson stems use their slot-less clamp for reasons of anti-knee knocking I guess. It's also a lovely design to machine. But as you've found, it lacks the capacity to cope with steerers of different diameters outside quite a close tolerance. <BR/><BR/>I can't remember the last time I banged a knee on my (bolted) stem though.brant@shedfirehttps://www.blogger.com/profile/04676267380073072679noreply@blogger.com
