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 fibre, 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.
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.
When SRAM launched their road technology from scratch, they reapplied their 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™ = Wider - Faster - Lighter
SRAM's WiFLi™ Technology is based on the compact 2 x 10 or 11 - two front chainrings and 10 or 11 gears in the rear - design inherent in SRAM RED, Force, Rival and Apex, which delivers a wider range of gears than your standard triple, faster shifts through two chainrings and every gear on the rear cassette, and with significant weight savings. It's technology from the company that continues to reinvent the cycling experience.
