SRAM Exact Actuation for precise and reliable 10-speed performanceDirect Route technology reduces shifting effortCassette with up to 36 teethClevis length available: medium1:1 ratio is the ultimate in design. Each pulled cable unit moves the derailleur in the same way. The ratio remains precise and smooth whether you're pedaling in mud, climbing rocks, or getting stuck in roots: wherever you are, whatever the conditions. It's reliable, durable and the easiest to adjust. The easiest to adjust. And it's no coincidence that it's the first choice of top mountain bikers. Do you get it? Well, I do. Exact Actuation When we launched our road technology from scratch, we applied our proven SRAM 1:1 activation ratio (shifter cable travel: derailleur movement) for a 10-speed rear shift. EA helps simplify/stabilize the complex action of balancing the design of the rear derailleur hanger, the limited space for the sprocket and the perfect cable tension. The result is the easiest index-controlle...
