Yeah, that seems to be the case. If you're building up a bike you can select those parts but I think Norco is one of the only companies that has grip shift specced on their bikes. Its too bad b/c alot of people don't get the chance to try out the SRAM X.0 stuff.

The SRAM X.0 setup though, is high end. The rear derailleur has carbon parts and the shifting is more crisp and precise than XT. I haven't tried XTR so, I'm not sure how it would compare to that.
