A-A-Ronwrote a review of SRAM XX1 Trigger Shifter on December 25, 2014
Familiarity: I've used it several times
Purchased this to complete my full XX1 drivetrain and couldn't be happier.
First off, I love the fact that you can upshift up to 5 gears at a time by pushing the trigger all the way down. Can easily go from 11th gear to 1st gear in two strokes.
Second, I love the fact that this comes with the coated and slippery shifter cable. It makes shifting that much quicker and smoother. (The desc. says it is Gore Ride-on brand cabling but I couldn't find any brand markings indicating this. The cable is coated with a black plastic-like substance and is also lubed)
Easy adjustment for position change and MMX compatibility. Lightweight carbon housing cover and triggers to boot!
Costs a few bucks more than the next models down however these are dollars well spent in my opinion.
Go for it!!
