SRAM Force 22 WiFLi , Rear Derailleur

Adopting all the technologies that provide the fastest, quietest shifting available, the new SRAM Force 22 Rear Derailleur has been designed with our Exact Actuation technology for precise, efficient shifting throughout the extended gear range. We have given and even refining tooth geometry of the jockey wheel. The result is that the chain that runs smoother and quieter than ever before. With all the additional technologies we’ve managed to keep the weight the same, at well under 200 grams.TechnologyAeroGlide PulleysNew tooth pulley design with a sound damping effect for a super efficient and silent ride experience. Bottom and top pulleys benefit from this feature.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. WiFLiSRAM's WiFLi technology accommodates a wider range of gears than a standard short-cage road derailleur. Compared to a triple chainring setup, it provides faster shifts and significant weight savings.Specifications for SRAM Force 22 Rear Derailleur• SPEEDS: 11-speed• MATERIAL: Carbon outer cage, Aluminium inner cage, Magnesium inner link (aluminium mid-cage)• WEIGHT: 187g (mid cage)• COMPATIBILITY: SRAM RED 22 & Force 22 Rear Shift/Brake levers, SRAM R2C Aero SL-1190 shifters, SRAM R2C Aero SL-1150 shifters, SRAM 900 Aero brake levers, SRAM 500 Aero brake levers• FINISH: Ice grey & black anodized• TECHNOLOGY HIGHLIGHT(S): Exact Actuation/ AeroGlide Pulleys/ WiFLi• HARDWARE: Aero designed stainless steel hardware
