This stunning model raises the bar once again for rear derailleur performance & is packed with some of the finest technologies around. What's most impressive is it
Includes:: Exact Actuation ratio which offers the widest range of adjustment combined with accurate geometry to create market leading 10 speed road performance. This is an ideal choice of a replacement for your old or worn-out existing model, for smooth & reliable shifting. Technologies: 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 & exact cable tension. The result: the easiest index shifting system to set up & it stays that way.
