It takes a great passion for the sport to fully appreciate SRAM RED. This blurs the boundaries between man and machine. The SRAM RED rear derailleur features our Exact-Actuation technology for precise, efficient shifting. Carbon, titanium and ceramic bearings round off the system. The result is a further contribution to the legacy of being the centre of the purest group for a perfect cycling experience.
AeroGlide selector wheels A new selector wheel tooth design with sound-damping effect ensures an unforgettable and trouble-free ride. The lower and upper pulleys benefit from this feature.
EXACT ACTUATION When we first introduced our road bike technologies, we again used our proven SRAM MTB 1 to 1 ratio (spring travel shift cable rear derailleur movement). EXACT ACTUATION helps to achieve a simpler and more stable balance between the design of the rear derailleur suspension, narrow gear rim spaces and precise tensile stress. The result: a shifting system that's child's play to adjust once and never again.
WiFLi = Wider - Faster - Lighter SRAM's WiFLi technology is based on the compact 2x10 design of SRAM Apex and Rival - two chainrings front and ten gears rear. This results in a wider gear range than with conventional triple chainrings and, thanks to the two chainrings and ten gears, it enables faster shifting operations with a significantly reduced weight. This is the company's latest technology that will further revolutionise the riding experience.
