Red Rear Derailleur

Although 12-speed cassettes have the mountain bike world abuzz, road looks to be firmly in 11-speed land for the foreseeable future, and no derailleur in SRAM's line gets through that gear range better than the Red Rear Derailleur. Billed as 'True 22', the pairing of Red's front and rear derailleurs allows you to utilize every one of these gears, in any combination, without adding any weight to the already outstanding Red drivetrain system. The Red Rear Derailleur stands in as an integral component of the Red groupset, calibrated for 11 speeds using the innovative technologies that have made SRAM Red an industry leader when it comes to exact, predictable shifting under the world's most demanding riding conditions.


When SRAM first introduced its 10-speed Red component group, the heart of the industry-shaking design was its 1:1 Exact Actuation technology. In ordinary terms, this means that with each shift the derailleur pulls the same exact length of cable, regardless of what gear you're in. 1:1 is simple to set up, it stays in adjustment longer, and it provides laser-accurate shifting. The 11-speed system builds on that 10-speed foundation, boating even tighter shifts than before as we now have smaller gaps between cogs.


The Red Rear Derailleur incorporates a clean, air-cheating, low-profile mounting bolt that's made of titanium to keep weight as low as possible. The long upper knuckle clears up to 28-tooth cogs, and it is made of extremely stiff forged aluminum to resist flex, which helps to maintain near-perfect gear alignment. The inner carbon fiber pulley plate has also been enhanced to resist flex, increasing rigidity for precise gear changes, and its low weight results in a light action.


The pulleys themselves were a focus area for SRAM engineers, and they improved weight, durability, and operation. Coined AeroGlide, SRAM optimized the jockey wheel's profile so that the chain will glide more efficiently over the tooth profile as it threads through the cage. This helped silence a notably noisy drivetrain and enhanced chain movement across the cassette. Most would call it a day with those advancements and skip out early for a ride, but SRAM's R&D team developed an elastomer coating to further quell pulley noise. The SRAM Red Rear Derailleur also receives a barrel adjuster for simple fine tuning.

Bought the Red22 4yrs ago. Just two yrs old and 13,000 miles of use, the parallelogram spring broke. Competitive Cycling was great by sending it back for me and getting me a new one. Only problem is, the replacement one just broke the same spring. 12,400 miles and just under 2yrs old. Can't justify the cost of a new one if it keeps letting me down. Will be buying a Force 22 at more than half the price.
