SRAM Exact Actuation for precise and dependable 10-speed performance. Carbon and alloy cage makes it light and tough - 204 grams for medium cage. 3 cage lengths available - Short for DH, Medium for 2X10 and Long for 3X10.
Direct Route Technology: Here's the dirt on middlemen: they suck. That's why Direct Route Technology™ doesn't have one. Instead, the cable routes directly to the actuation mechanism. Result? Less friction. Less effort. More oomph. Plus it's impervious to cable housing damage. Nice.
Exact Actuation: When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.
