SRAM Red 22 WiFli 11 speed Rear Derailleur

SRAM RED 22. When SRAM re-introduced SRAM RED in 2012 there was simply nothing more SRAM could add to make it better. SRAM RED was all new, re-designed throughout, with innovations SRAM has spent the past year touting and their athletes proving. It was loaded with features and benefits that matched the needs of professionals: fast, light, aerodynamic, ergonomic, near-silent, and, of course, trim-less, with ground breaking Yaw™ technology. Adding two more gears to that combination was arguably the only improvement required. The added benefit is that now, without adding weight, SRAM maintains a system that shifts incredibly fast upfront, and with the best and smoothest gear transitions in back. And, for the first time available anywhere, the system gives you twenty-two gears. No compromise and no trim, what SRAM is calling True 22, in any gear combination. Welcome to SRAM RED 22.

If you want for the fastest, quietest shifting around, look no further. The new SRAM RED rear derailleur has been designed to deliver the performance advantage you‘ve come to expect from SRAM. The derailleur is designed with Exact Actuation technology for precise, efficient shifting.
SRAM has paid rapt attention to the finer details, like adding a hollow titanium anchor bolt and even refining tooth geometry of the jockey wheel. The result is that the chain runs through the new RED rear derailleur smoother and quieter than ever before.
AeroGlide Pulleys: New tooth pulley design with a sound damping effect for a super efficient and silent ride experience. Bottom and top pulleys benefit from this feature.

• New silent shifting with optimized AeroGlide lower pulley, ceramic bearings.
• New spring-fixed barrel adjuster.
• New chain pulley cage adds precise chain management.
• Titanium pinch bolt keeps a low profile while minimizing weight.

WiFLi™ = Wider - Faster - Lighter. SRAM's WiFLi™ Technology is based on the compact 2x10 - two front chainrings and 10 gears in the rear, which delivers a wider range of gears than your standard triple, faster shifts through two chainrings and 10 gears, and with significant weight savings. It's the newest technology from the company that continues to innovate the cycling experience.
WiFLi™ is all you need to know…

• Wider – a wider range of gears for every climb and any descent
• Faster - two chainrings shift (and set-up) much faster and more easily than three
• Lighter – as much as 274g (9.8%) less than the most popular road triple
• Much improved Q-factor - improved heel clearance
• Easier set up - two is easier than three

Features:

• Material: carbon cage inner parallelogram made of carbon aerodynamically shaped small parts made of titanium
• Weight: approx. 145 g (short cage)
• Version (2/3 speed): 2x11-speed
• Cage length: medium
• Largest sprocket: 32

Exact Actuation 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.

Compatibility: compatible with SRAM Red, Force and Rival Double Tap Controls. Not compatible with products of other manufacturers.
