The Shimano Deore XT M8000 rear derailleur Delivers reliable and precise shifting with a stiff and lightweight open design. Its Shadow design has a slant angle that’s been optimised for use with larger sprockets and the cage 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.

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 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.
The SRAM NX rear derailleur provides the same smooth, reliable shifting action as SRAM’s XX1 model - from the larger upper pulley offset to the 12-tooth X-SYNC™ pulley wheels. By eliminating unwanted chain movement, its X-Horizon™ cage 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. 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
The Shadow features a super low profile design that reduces the risk of damage from trail side hazards and the single tension spring prevents contact with the chainstay resulting in a silent ride.
This design ensures precise operation with reduced friction and maximum shifting rigidity. Also, the Centaur is only made in one cage size and compatible with cassettes with up to a 32 tooth sprocket, so there's no need to swap the mech when you want to run a different cassette range. The Centaur rear mech features trickle-down technology from Campagnolo's top-end models, making it a race ready component, but at a more wallet friendly price!

No, Shimano direct mount hangers are proprietary and are not compatible with Box derailleurs. Is the Box Three Prime 9 Derailleur compatible with other 9 speed components? No, traditional 9 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 Three 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.

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
