Technology: Exact Actuation Ratio, Direct Route Technology
SRAM X0 DH 10 Speed Rear Derailleur Technologies:
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.
