The SRAM Force WiFli rear derailleur represents the same design philosophy that has yielded SRAM’s best-in-class products for the mountain bike (MTB) market. It takes advantage of Exact Actuation, an actuation ratio that delivers precise 3mm shifts in every gear along with the widest range of adjustments available, delivering the best 10-speed performance in the sport. Crafted with cutting-edge materials, the SRAM Force WiFli rear derailleur - 10 speed model includes a carbon fibre outer cage and a magnesium inner link. The final result is an impressively lightweight unit that tips the scales at only 190g. With WiFLi, the rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette. The range of gears is wider than the standard triple chainring system and saves well over 250 grams. WiFLi offers a wider gear range and is compatible with cassettes up to 32T. Exact Actuation means precise, even gear changes throughout the shifting range. Technologies: Exact Actuation™: Simplified and stabilised shifting over tight cog spacing found on modern cassettes. By using exact cable tension, the end result is the easiest index shifting system to set up and it stays that way WiFLi™: WiFLi™ = Wider - Faster - Lighter - SRAM's WiFLi™ Technology is based on the compact 2 x 10 - two front chainrings and 10 gears in the rear - a design inherent in SRAM Apex and Rival. This delivers a wider range of gears than your standard triple, faster shifts through two chainrings and 10 gears, and with significant weight savings. It's an updated technology from the company that continues to innovate the cycling experience
