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.

Newly redesigned the Shimano M7000 SLX 11-Speed Shadow+ Rear Derailleur takes cutting edge technology from the XTR and XT groupsets and brings it down to a more affordable price range. Brings Cutting Edge Technology from XTR and XT Level to an Affordable Price PointShadow+ Clutch Mechanism for Excellent Chain RetentionShadow Design Optimised For 40-46t SprocketsDirect Cable Routing Prevents Snagging on Trail Size HazardsSealed Bearing PulleysThe lightweight and low profile design combined with the direct cable routing prevents those unwanted snagging moments on undergrowth or something a little harder, helping to keep your shiny rear derailleur in one piece and still attached to the bike. Drivetrain security goes even further with the Shadow+ Clutch design. As we push our bikes harder dropping a chain is the last thing you need. With Shadow+ dropped chains should be a thing of the past. The M7000 SLX rear derailleur is optimised around 40-46t cassette sprockets, being compatible with a maximum of a 42t cassette when used with a double chainset, or with a 46t if used with a single chainring. Sealed bearing pulleys ensure this derailleur is designed to go the distance. Tough, light weight and great value, SLX M7000 is a great choice for those seeking top performance without having to re-mortgage!
When it comes down to performance and durability the new Rival 22 rear derailleur matches the top end Force and Red derailleurs with the only difference being a slight weight difference. The derailleur is constructed from an aluminium inner and outer cage as well as an aluminium b-knuckle. Using Exact Actuation, each gear shift is fast and accurate, with the redesigned AeroGlide jockey wheels keeping things quiet and smooth.
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.
