Enhanced with X-Horizon shifting technology, the SRAM GX 11 speed rear derailleur eliminates ghost shifting and reduces shift force and chain slap. It also features the Cage Lock features, which locks the derailleur out of the way when removing and installing wheels to the process much easier. Technologies: Cage Lock: With Cage Lock technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place. Roller Bearing Clutch: Roller Bearing Clutch (RBC) rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With RBC technology, derailleur bounce and chain slap are eliminated without sacrificing precision. X-Actuation: Developed specifically for SRAM 1X, X-Actuation keeps shifting sharp and consistent across the entire 10 to 42-tooth cassette. X-Horizon: The X-Horizon rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears. X-Sync: SRAM X-Sync 1X chainrings provide the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrain.
By eliminating unwanted chain movement, X-HORIZON™ shifts faster, reducing shift effort and chain slap. Eact Actuation™ for fast and accurate shifts using SRAM’s 1:1® actuation ratio (shifter cable travel : derailleur movement) X-Sync™ pulley features a 12-tooth design that helps control the chain’s lateral movement Roller Bearing Clutch™ controls chain tension for consistent shifting X-Horizon™ straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force Cage Lock™ technology makes for fast wheel changes or chain installation

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
