This Box Four rear mech is the base of Prime 9 Technology, which offers an affordable clutch based 1 by 8 speed derailleur that is simple and light. This makes it an ideal candidate for every entry-level bike that traditionally has a 3 by drive-train that is neither durable nor user friendly. Compatibility: • Box Four 8 Speed Shifter Black • Box Four 8 Speed 116 Link Chain Natural • Box Four 8 Speed 11-42T Cassette Black • Box Four 8 speed Wide/Narrow Chainring 104BCD 32T Black FAQ: Are Box Prime 9 derailleurs compatible with Shimano "direct mount" hangers? No, Shimano direct mount hangers are proprietary and are not compatible with Box derailleurs. Is the Box Four Prime 9 Derailleur compatible with other 8 speed components? No, traditional 8 speed systems use a Cable Pull that is not compatible with Prime 9. Are Box Prime 9 derailleurs compatible with drop bar (road) shifters? No, Box Prime 9 derailleurs are not currently compatible with drop bar shifters, but we do offer a clamp for our shifters to mount on some 31.8mm drop handle bars. How should I clean my Box Four Prime 9 derailleur? We suggest removing the derailleur from the bike and using a soft bristle brush or rag with soapy water or a mild de-greaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.
By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever. 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 Features 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 chain rings 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.
The X-Actuation technology eliminates slop whilst the Roller Bearing Clutch technology delivers maximum stability making the SRAM GX 10 speed rear derailleur great over punishing terrain. This technology also removes shifting variation and offers you incredible shifting speed and precision. Cage Length Information: Short Cage option has a total chain wrap capacity of 30T (Ideal for use with downhill (DH) / enduro bikes with a smaller chainring up front) Medium Cage option has a total chain wrap capacity of 35T (Ideal for use with all mountain (AM) / trail bikes with a medium chainring up front) Long Cage option has a total chain wrap capacity of 47T (ideal for use with touring bikes with a larger chainring up front)
WiFLi™ WiFLi = Wider - Faster - Lighter SRAM's WiFLi Technology is based on the compact 2 x 10 or 11 - two front chainrings and 10 or 11 gears in the rear - design inherent in SRAM RED 22, Force 22, Rival 22 and Apex, which delivers a wider range of gears, up to 11-32, than your standard triple, faster shifts through two chainrings and every gear on the rear cassette, and with significant weight saving. WiFLi cassettes are also available for Force CX1. Exact Actuation When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : dérailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear dérailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way. AeroGlide Pulleys New tooth pulley design with a sound damping effect for a super efficient and silent ride experience. Bottom and top pulleys benefit from this feature.
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. S2 System (Secure Shifting System) The special support system built into the derailleur safeguards working of the drivetrain, guaranteeing maximum compatibility with frames on the market. In other words a derailleur fitted with an accessory that, when assembled on the frame, safeguards the working of the drivetrain on any frame. 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
Thanks to the clutch system on the Shimano Deore M6000 rear derailleur, you can push yourself harder on the roughest trails, without worrying about chain slap or drop. It also delivers ultra-quick, quiet shifts and with its fluorine-coated bushings, shifting requires minimal rider effort. Additional Features: DYNA-SYS compatible Low profile design reduces the risk of damage Direct mount compatible Single tension spring prevents contact with the chainstay Direct cable routing prevents snagging Improved stability and chain retention longevity Compatible with wide range 11-36T cassette (medium GS version only) Fluorine-coated link bushings for low-friction operation Technologies: Shadow+: This technology provides a less distracting, quiet drivetrain as the rear derailleur stabiliser reduces chain slap. A simple solution for chain drop, which is lighter and more efficient than roller type chain devices.
Featuring an adjustable chain stabiliser, the stunning Shimano GRX 400 rear derailleur prevents chain slapping and drops when riding over harsh surfaces. Whether you're riding after work with your buddies or taking your road exploration further, its switch stabiliser lets you turn it on/off based on the terrain. Smooth and reliable for mixed surface shifting, the RX400's gravel-tuned clutch tension helps you get the best experience out of every ride. Shimano has also developed its design specially for gravel bikes by ensuring a wider range that's suitable for use with larger sized tyres. Taking your riding a step further, you'll also benefit from the industry-leading technologies that the Shimano GRX 400 rear derailleur - 10 Speed model has, as these will keep you in control. Behind the "click" you hear and feel every time you shift, its Shimano Index Shifting System technology provides you with light, precise and consistent gear changes.
This MTB rear mech features Shadow Plus technology, which uses a super-low profile design and an optimised slant angle for exceptionally light shifting action on the toughest of rides. Shadow Plus also uses a chain stabilising switch that when on will reduce chain bounce in rough terrain, so you can enjoy a more confident shifting experience as you explore the trails.
