Leveraging the legendary history of SRAM shifting, the XX Rear Derailleur delivers incredible speed and precision. Sealed ceramic pulleys give you the highest levels of durability. The carbon fibre cage has a dedicated length specific to 2x10. EXACT ACTUATION technology eliminates slop and shifting variation. It’s a rear derailleur perfected for ultimate off-road performance.TechnologyDirect RouteHere'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 ACTUATIONWhen 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.  Specifications for XX Rear Derailleur •SPEEDS: 10-speed •MATERIAL: Carbon Fibre Composite cage •WEIGHT: 181g •BEARINGS: BLACKBOX ceramic bearing pulleys •CAGE SIZES: Long (93mm), Medium (80mm) •MAX TOOTH: 36t •TECHNOLOGY HIGHLIGHT(S): EXACT ACTUATION •P KNUCKLE: Grilon composite •B KNUCKLE: Forged AL-7075-T6 •HARDWARE: Titanium and AL-7075-T6; TORX T25 bolts •BOLTS: AL-7075-T6

Precision-engineered Dura-Ace 9-speed index bar end shift levers. Superior Dura-Ace quality means reliability and durability. Easily fit into bar ends and secure firmly for assured shifting.

Deore mountain bike Rapidfire shifter pods featuring 2-way release for cost effective 9-speed shifting performance. 2-way release allows shifting from various riding positions; the upper lever still performs the same shift function, but it can now swing in either direction allowing it to be released by the thumb or index finger. Mega9 compatible - for use with precision 9-speed drivetrain. Pod design allows the use of these shifters with any brake lever. Low-friction design means that shifters have a light and responsive short-stroke action that reduces shifting effort.
