Shimano Saint RD-M820 10 Speed Rear Derailleur, SS

Features and Benefits:

• Direct Mount gives a simpler, cleaner look
• Deore XT Shadow+ Dyna-Sys 10-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
• 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 wheel
• Direct cable routing prevents snagging from any trail side hazards
• All-alloy construction leads to lower weight without compromising strength and durability
• 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

Thanks to its low-profile design and close ratio compatibility, the Shimano Saint M820 rear derailleur is ready for the rough and tumble world of gravity racing.

Shimano's new Direct Mount 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.

The RD-M820-SS rear derailleur has a mode converter which can be used to switch between 2 modes, with the mode converter installed the derailleur can be used with wider range cassettes up to a 36T maximum sprocket (All Mountain mode), when the mode converter is removed the derailleur can be used with close ratio cassettes up to a 28T maximum sprocket (Downhill mode). The mode converter alters the mounting angle of the derailleur, when installed it moves the derailleur further back, pulling the derailleur out of the way and allowing it to cope with wider range cassettes up to 36T.
