The RD-M786 rear derailleur with Shadow technology is optimised for trail riding with the addition of an innovative new friction clutch mechanism which actively prevents the derailleur cage moving forwards under tension, all but eliminating chain slap and helping to prevent chain suck and dropping, ideal for more aggressive trail riders. The tension can be removed with the used of an integrated lever which facilitates easy wheel removal and gear indexing.The familiar 'Shadow' low profile design architecture keeps the derailleur and it's pulley cage closely tucked in to prevent impact damage from trail hazards whilst also eliminating chainstay contact and trail chatter, similarly the direct cable routing prevents snagging. Whilst a modified cable pull-ratio (which requires the same pressure regardless of the position on the cassette) helps resist the effects of cable contamination to maintain shift quality for longer.

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.
