Love, love, love these shifters. My bike came with XTR rapid demise, and was the second thing to go (after the forks). The X9 is everything that XTR wasn't. Gunshot engagement, thumb friendly design.... you can even reach under with the index finger and pop a down shift if you so desire. They're attractive, simple, reliably built. Paired with an X9 and you've got the rear shifting of your freeride bike dialed.
