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.
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 axel sizes and move suspension pivots Direct Mount gives a simpler cleaner look Deore XT Shadow Dyna-Sys11 11-speed rear derailleur delivers reliable and precise shifting with a stiff and lightweight open design 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 more stable drive and shifting. This can be switched off to remove the wheelShadow design slant angle has been optimized for use with 40-42T sprockets Direct cable routing prevents snagging from any trail side hazards Four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trails High rigidity wide outer link braces the pulley body to increase pivot joint rigidity resulting in a crisp shift Strong return spring for a positive shifting feel Durable sealed bearing pulleys 40T (42T for 1x 11-speed) capacity SGS cage
