I honestly couldn't tell you, but ...... your post reinforces my personal style of only upgrading/swapping out one part at a time (unless physically impossible due to whatever circumstance).....makes it easier to track down what went "wrong" after the fact. When you change more than one thing at a time, complicates the troubleshooting process.

Now my question is, does anyone know if there is a physical difference between an '02 rear carbon triangle, and an '05? I'm having issues with chain suck, among other things. I'm not sure if this is because of the new triangle, or because of an XT m760 crank that I put on at the same time. Any thoughts would be great!
