Technologies Exact Actuation When SRAM launched their road technology from scratch they reapplied their 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. Cage Lock The first rear derailleur of its kind, SRAM TYPE 2 lets you push your cage forward & lock it into place with the push of a button. This creates slack, removing all tension from the chain. With Cage Lock, TYPE 2 makes wheel removal & installation—as well as chain installation—easier than any other derailleur on earth. 1. Just push the cage forward—creating slack—and lock it in place. 2. The chain stays perfectly loose, letting the derailleur swing out of the way. When you’re ready to ride again, simply unlock the cage & go. Roller Bearing Clutch Designed for X0 & X9 families, TYPE 2 rear derailleur delivers maximum drivetrain stability—even through the most punishing technical terrain. With Roller Bearing Clutch™ technology, SRAM TYPE 2 eliminates derailleur bounce & chain slap without sacrificing precision. • A one-way roller clutch controls chain tension for consistent shifting • Needle bearing • Self-lubricating for consistently smooth action • 360 degree clutch force for reliability & durability • TYPE 2’s clutch force comes factory calibrated by SRAM • Consistent shifting feel • Maintenance free clutch design
