SRAM's Red WiFli rear derailleur has now been updated and refined, with 2 extra gears, for Red 22. Like the Red WiFli model the new 22 version has an extended cage to accommodate an 11-32T cassette. Using SRAM's Exact Actuation, the rear derailleur is extremely responsive to any shifter movement, for super fast and precise shifting. Additional features include changing the profile on the jockey wheels to help the chain run smoother and quieter, aided by the ceramic bearings for super smooth spinning. For the ultimate in fast and positive shifting in a superlight package, the SRAM Red 22 WiFli derailleur is the choice.
The SRAM Force Rear Derailleur is crafted with cutting-edge materials, including a unidirectional carbon-fiber outer mid cage and a magnesium inner link. The derailleur takes advantage of Exact Actuation, an actuation ratio that delivers precise 3mm shifts in every gear along with the widest range of adjustment available, delivering the best 10 speed performance in the sport. With WiFLi, the rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette. The new range of gears is wider than the standard triple chainring system and saves well over 250 grams.
Designed around the extra 2 gears in a SRAM True 22 setup, the SRAM Force 22 rear derailleur works with the Yaw front derailleur to ensure fast, smooth, quiet and efficient throughout all 22 gears with no chain rubbing or excess noise. With WiFLi, the rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette. The new range of gears is wider than the standard triple chainring system and saves a significant amount of weight. Using Exact Actuation, each gear shift is fast and accurate, with the redesigned AeroGlide jockey wheels keeping things quiet and smooth. Carbon and aluminium cages, along with a magnesium inner link keep the weight very low at only 178g.
