SRAM X9 10 Speed Trigger Shifter 2012
The SRAM X.9 Trigger shifter features EA (Exact Actuation) technology for quick and precise shifts. The essence of this system is that it uses a 1:1 ratio for cable pull/derailleur movement. The effect is easy setup, adjustment, and a system that is more tolerant of slight cable stretch and/or friction in the housing. Cable replacement is easy. Simply pop off the top cover, pull out the old cable, thread in the new one, and take off for a ride.
The X.9 Trigger Shifter is also compatible with MatchMaker, meaning you can mount them on one clamp along with your brake levers and X-Loc remote for your fork if you have it. The benefit is that your handlebars will be less cluttered and the Matchmaker-X system saves weight over multiple clamps.
This shifter is sweet, it takes large shifts yet is still precise with single shifts. Never had a problem with them and they simply work. Great product.
