Elegantly designed, the XTR M9100 Rear Derailleur is suitable for use with Shimano's 12-Speed drivetrain system and comes equipped with oversized 13T pulley wheels and an updated Shadow RD+ mechanism which is narrower and more discrete to outfox the flow-killing risks of hard-riding mountain biking. Aluminium-made, this compact and convenient derailleur belies its size to give hugely impressive performance.
The XTR M9100 Front Derailleur from Shimano offers top-notch performance, shifting accuracy and drivetrain smoothness in a lightweight, durable and elegant package. Boasting the Shimano Side Swing engagement, this stunning derailleur effortlessly transitions the chain across the front chainrings with unmatched efficiency and accuracy. Its Side Swing mechanism firmly places Shimano’s stance at the peak of front derailleur technology and provides competition proven reliability regardless of the terrain you find yourself soaring across.
This stunning model features oversized 13T pulley wheels, updated Shadow RD+ mechanism and is tailored specifically to provide maximum chain retention and shifting accuracy across the new Shimano 12-Speed drivetrain transmission system. This derailleur has been redesigned to ensure that chain tension is decreased when in the low gear position (41T on cassette), which makes shifting easier while the Shadow+ mechanism ensures chain stability.
The SRAM Apex 1 rear derailleur makes that perfect gearing choice a reality with clean, crisp shifts, thanks to SRAM’s X-Horizon™ geometry and the Roller Bearing Clutch™. Just go: Apex 1 will get you there.
Featuring a proprietary SRAM actuation ratio, professionally engineered cage design and intuitive adjusters, the new SRAM Apex front derailleur establishes itself as a legitimate high performance product. New SRAM® Apex is the perfect blend of technology and performance, so all riders can challenge their personal limits. SRAM® Apex has double chainrings, which are simpler, lighter, faster, and in every way, just better than a triple. And with a gear range that's wider, making climbing easier and descending faster, why would you ever go back to three?
The EX1 also benefits from many of the same technologies that are seen on SRAM’s top-end XX1 X01 mechs. This means it gives you lightning quick, accurate shifting and highly efficient chain retention. 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 push the cage forward to create slack and lock it into place. Roller Bearing Clutch™: SRAM's Roller Bearing Clutch™ rear derailleurs deliver maximum drivetrain stability, even through the most punishing terrain. With Roller Bearing Clutch™ 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 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's X-sync™ pulleys and chainrings 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, helps manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chainrings 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.

The SRAM Force 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 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 174g. 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.
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
With the SRAM Force 22 rear derailleur, SRAM has refined the tooth geometry of the jockey wheels. The result is that the chain runs smoother and quieter than ever before. With all the additional technologies, they have still managed to keep the weight the same, at well under 200 grams. Fitted with AeroGlide Pulleys with an updated tooth pulley design for a sound damping effect, the Force 22 road derailleur brings you an ultra-efficient and silent ride experience. The bottom and top pulleys benefit from this feature. Technologies: Exact Actuation™: When SRAM launched its road technology from scratch it reapplied its mountain bike (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.
The Yaw™ rotating front derailleur cage was just one more elegant solution to a problem that plagued drivetrains for decades. Instead of multiple shifts using trim, with confusing microshifts, the SRAM Force 22 Yaw™ Front Derailleur actually rotates to maintain a consistent angular relationship with the chain. As a result, shifts feel more direct, more precise, system that works as one with the chain, cransket and chainrings.
Featuring cutting-edge materials such as a carbon fibre outer and mid cage and a magnesium inner link, the WiFLi version of the SRAM Force 22 rear derailleur tips the scales at a mere 190g. Its 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. Fitted with AeroGlide Pulleys with an updated tooth pulley design for a sound damping effect, the SRAM Force 22 rear derailleur - medium cage type brings you an ultra-efficient and silent ride experience. The bottom and top pulleys benefit from this feature. SRAM has also refined the tooth geometry of the jockey wheels. The result is that the chain runs smoother and quieter than ever before. With all the additional technologies, they have still managed to keep the weight the same, at well under 200 grams.
