I have a nice 46-tooth Stronglight chainring made for, I believe, the 105 bis crank. It's 122 BCD, and in new and unused condition. If anyone is interested, I'd like to trade it for another 46-tooth ring of the same BCD but in the Model 93 pattern. This one would work fine on a 93, but wouldn't look quite right. I would apologize for being so fussy, if not for the fact that so many around here are as bad as I am about such things, or even worse.
I also need a direct-mount long cage Simplex derailleur--something along the lines of a 610 or 810. I'd trade my chainring either. I have other trade goods, too.
