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 auto trim technology and an optimised cage design, the XT Di2 M8070 front mech tracks the movement of the rear derailleur and delivers perfect shifts from every gear combination.
The Shimano Deore XT M8000 rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design. Its Shadow cage has a slant angle that’s been optimised for use with larger sprockets and it features a super low profile design that reduces the risk of damage. The Shadow Plus system uses a chain stabilising switch that when on, reduces chain bounce in rough terrain maintaining a more stable drive and reliable shifting. This can be switched off to remove the wheel. The Direct Mount system on the Shimano Deore XT M8000 rear derailleur 11 Speed model gives you more space around the rear frame dropout. This results in easier rear wheel removal but also allows frame designers to shorten chain stays, increase axle sizes and move suspension pivots.

The design is derived directly from the 11-speed components with the oversized outer plate to provide greater rigidity to the entire system. The surface treatment protects it from corrosion and ensures that the Veloce(TM) rear derailleur maintains its performance over time.
Tough, aggressive and lightweight, Dyna-Sys11 11-speed SLX rear derailleur uses revolutionary features from XT and XTR at an affordable price point. Shimano's Direct Mount compatible Rear Derailleur system gives more space around the rear frame dropout resulting in easier rear wheel removal but also allows frame designers to shorten chain stays, increase axle sizes and move suspension pivots. Shadow Dyna-Sys11 11-speed rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design. The Shadow features a super low profile design that reduces the risk of damage from trail side hazards. The shadow plus chain stabilizer tension can easily be adjusted externally via a hex key. Shadow Plus uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining a more stable drive and shifting. This can be switched off to remove the wheel. Direct cable routing prevents snagging from any trailside hazards. Four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trails, whilst high rigidity wide outer links brace the pulley body to increase pivot joint rigidity resulting in a crisp shift.
In keeping with its philosophy and history, Campagnolo has gone even further, and created the triple crankset with the best ""U"" and ""Q"" factors in its class. This outstanding result offers tangible benefits to the rider: derailing speed and precision of a par with double drivetrains, and perfect hip-knee-foot alignment for maximum pedalling efficiency and maximum joint protection.
The X-Actuation technology eliminates slop whilst the Roller Bearing Clutch technology delivers maximum stability making this great over punishing terrain.
Compatible with a cassette tooth count range of 11-25T to 11-30T and adopting Shadow technology from Shimano's mountain bike (MTB) range, the Shimano Ultegra R8000 rear derailleur ensures a smooth ride in even the highest and steepest mountain areas. The integrated Shadow technology is race-proven and with its low profile design, this slick operating road rear derailleur is aerodynamic, more compact and fits closer to the frame, ensuring less damage in a crash. Technologies: Shadow: Shadow design features a super low profile design and optimised slant angle for super light shifting action. HG-EV: HG-EV cassette sprocket is for rider-tuned gear combination and cadence management. Shimano provides the optimal 11-speed drivetrain gear ratio; you can choose from the wider and closer gear combinations available to match various riding disciplines. HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved HYPERGLIDE shifting HG-X11 Chain Compatible: Silky driving, accurate shifting. HG-X11 directional chain ensures smoother shifts and greater overall performance. The right and left sides are optimised for front and rear shifting respectively
With the new Super Record, Record, and Chorus groupsets, shifting is extremely easy thanks to the long front plate of the front mech body, meaning greater leverage and therefore truly reduced movement when shifting. Shifting precision is achieved thanks to the design of the new narrower cages. The semi-inner cage, in aluminium, has features that improve shifting speed. The most efficient downshifting on the market is achieved thanks to the integrated outer semi-cage in carbon fibre, a distinctive Campagnolo feature on the Super Record and Record front mechs, or by the positioning of a plate on the tip of the Chorus front mech. Special Inner Cage Design The inner semi-cage, in aluminium, has features that improve shifting speed, give greater rigidity and provides more space for chain crossovers
The SRAM NX Eagle rear derailleur features the 1x specific X-Horizon cage design, which ensures capacity and shifting accuracy for the huge 11-50T cassette range while complimenting the smooth shifting performance of the Eagle 12-Speed drivetrain transmission. This tough mountain bike (MTB) rear mechanism also boasts the SRAM Type-3 Roller Bearing Clutch to provide industry-leading durability, quiet performance and unmatched shifting stability. 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: The Roller Bearing Clutch delivers maximum drivetrain stability even through the most punishing terrain. This stability benefits the drivetrain dramatically, as derailleur bounce and chain slap are eliminated without sacrificing precision
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.
