So venerable list members, all this talk of loosening recalcitrant fixed cups has me thinking. I know that some fixed cups are tight, maybe even siezed in there. Anyway, I have at least 2 bb's that I have had in bikes in the past. One is a TA, the other has no name on it. Both of them use a screw in cup and mere lockrings on both sides of the BB shell for adjustment and tightness. Now, I would wager that a lockring can't be snugged as tight as a generic Campy fixed cup (as the ring squishes under the lockring tool through tightening).............so it begs the question: Do Fixed Cups have to be installed as tight as they seem to be installed, or do they function quite well with far less torque applied when installed? They are threaded left-handed, at least the English threaded are, and that would seem to be so they would tighten in use anyway. one wouldn't want them moving around in there, but if a mere lockring can do that.....
