Thanks. The thing I like about the new XTR stuff is that its really pretty, looks well made. I've been thinking about the SRAM X0 derailleur though, as well as magura brakes, or hayes, but I dunno. I'm into building race cars and have quickly found that this bike stuff is almost as complicated as building a 32 valve V8...

Other than weight would I notice anything if I started swapping components for the latest greatest? For example, I was told if I upgraded my crank to the Shimano XTR since its lighter and more rigid it would be more efficient for climbing. How about the deraileur or brakes? Would there be a seat in the pants feel in shift quality or lever effort?

I find myself laughing right now since its like I'm talking about one of my mustangs and all the upgrades I did to it.
