I'm not really trying to change the gearing from my present setup, Bill. What I am doing is upgrading from my Shimano FC-M440 to something lighter, stronger (7075 alloy), not too expensive and silver.
The Stronglight came to mind, but it apparently won't work. That ok, cause I am not thrilled about having a 30T chainring as my smallest one, up front.
My mechanic suggested the Shimano XT, but I just don't want the black chain rings. Also, my tech was not able to tell me what kind of alloy Shimano uses on the XT. I can't find any info on it. Preferably, I want 7075 in both the rings and the crank arms.
The bike is a Raleigh M80. I don't know the teeth count on the 9-speed SRAM cassette.
