and i was on the gary fisher site and saw zr9000 then went to trek and saw zr9000... now this explains it all
You're joking right????
A gripshift has ONE moving part ... the barrel. If you want complexity try cracking open your trigger shifters sometime.
BTW, I think either are fine. It's a matter of personal preference. My preference are Grip Shifters. "Accidental" shifting is pretty negligible once you get used to them.
