SRAM&8217;s 2X10 & 3X10 Exact Actuation for precise & dependable 10 speed performance. Exact Actuation: When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio &40;shifter cable travel: derailleur movement&41; for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design tight cog spacing & exact cable tension. The result: the easiest index shifting system to set up & it stays that way. Match Maker X Integrated: The Match Maker X clamp offers a clean integrated system that conserves handlebar real estate while putting your XLoc suspension controls along with your SRAM XX or X0 shifters & matching AVID brake levers right where you want them. If you&8217;re using the XLoc remote this clamp is built right for you.&8226; Compatibility: SRAM 1:1 rear derailleurs SRAM Shimano front derailleurs &8226; Technology: Impulse Technology
