XT ! XT ! XT ! I got a custom built frame and built it up in the image of the Gordon Rock N' Road with all XT -- and I'm in love. It's a BILF. The XT M760 crank has 44-34-24, and the M761 has (I think?) 48-36-26. BTW- the XT group is going to be all new for 2008, and it looks pretty cool. The rear derailleur body is cast so it actually looks like an "X". Maybe, since they're coming out with latest/greatest, you can get a steal on the existing stuff.
