Yeah, that threw me off for a second because in the pics of your drivetrain, I clearly saw a Shimano rear derailleur. I saw the SRAM shifter and wondered how you got that to work with the different ratios. I love my SRAM X-7 rear on my Gary Fisher. I have some X-9 shifters waiting to be put on, sitting on my shelf right now. The bike came with X-5 shifters on it, I just want something a little faster.
