Teebird!wrote a review of SRAM X0 Trigger Shifter 9 Speed on October 31, 2012
Familiarity: I've put it through the wringer
I didn't know when I bought these that the thumb lever is adjustable. Great for lengthening the front chainring throw so you can "push" it up with one throw. These are solid well built shifters. I like the SRAM's engagement but it is not for the weak thumbed. Very solid shift. Love these shifters and can't beat them for the Chainlove price!
