Supercharged shifting with bulletproof precision. Sacrifice nothing???not durability, dependability, or performance - nothing. The new Rival rear derailleur matches SRAM's Exact Actuation with tried-and-true competition-proven design and construction. Exact Actuation delivers even gear changes over the entire shifting range via a precise 3mm adjustment from gear to gear. Maximized for 10-speed systems, the Rival's design is descended from SRAM's legendary MTB rear derailleurs. It weighs only 188g but features an all-aluminium B-knuckle inner link and cage that can stand up to any serious rider's demands
