Your reading the Sheldon chart wrong. Notice that 'any 9-speed shifter' is listed twice. One listing says it is...if you read straight across and I think that the error while the other listing says it isnt. Too many times individual or buisness with a fniancial gain are too quick to put info on the 'net. I have nothing to gain and only 1 thing (my rep on BF) to lose. IIRC the last time I put smack down on SB, PW ad VO for a glaring error on their pages they never appeared here to contradict me.
