Featuring cutting-edge materials such as a carbon fibre outer and mid cage and a magnesium inner link, the WiFLi rear mech tips the scales at a mere 190g. It’s wide range of adjustment and large cassette capacity makes it suitable for all types of riding, including epic climbs in the mountains and the muddiest cyclocross courses. Technologies: Exact Actuation™: When SRAM launched its road technology from scratch it reapplied its MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 11 speed rear shifting. EA helps to simplify/stabilise 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 11 – two front chainrings and 11 gears in the rear – design inherent in SRAM Apex and Rival, which delivers a wider range of gears than your standard triple, faster shifts through two chainrings and 11 gears, and with significant weight savings. It’s the newest technology from the company that continues to innovate the cycling experience.
