Sram Red Rear Derailleur

The Sram Red Rear Derailleur provides precise and quick shifting as well as a silent operation for your practices of road cycling. It is compatible with 24 and 32 teeth and 11 speeds. This bike rear derailleur is made of carbon and ceramic pulley bearings. It features Exact Actuation technology that favors precision, speed, and silent operation. It includes a new AeroGlide toothed pulley design that provides cushioning, less noise, and efficient driving. It takes a degree of passion for the sport that Can´t´ be faked to fully appreciate SRAM RED.It was created to blur the boundaries between machine and athlete.The SRAM RED rear derailleur was designed with our Exact Actuation® technology for precise, efficient shifting.Carbon fiber, titanium, and ceramic bearings complete the spec.The result adds to its legacy as the heart of the purest groupset for the pursuit of cycling excellence.Features:- SRAM 11-speed compatible- WiFLi® option- Carbon cages, carbon inner links, titanium hardware- Exact Actuation® shifting provides fast and accurate shifts- More clearance with 28t cassettes thanks to a longer B-knuckle- Silent shifting with optimized AeroGlide® pulleys, ceramic bearings- Spring-fixed barrel adjuster- Chain pulley cage adds precise chain management- Titanium pinch bolt keeps a low profile while minimizing weightSpecifications:- Speeds:11- Material:Carbon cages, Carbon inner links, Aero designed titanium hardware- Weight:145g (short cage), 165g (mid cage)- Compatibility:SRAM RED® & Force 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:Falcon grey & black anodized- Technology Highlight(s):AeroGlide Pulleys®, Exact Actuation®Technology: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.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 and exact cable tension.The result:the easiest index shifting system to set up and it stays that way.WiFLi®:- SRAMs 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.For 2x10V systems.- Compatible with cassettes 11-42T.
