Shimano RD-M820 Saint 10-Speed SS Rear Derailleur
- Ready for the rough & tumble world of gravity racing
- Short cage prevents chain slapping & dropping
- Shimano's new Direct Mount Rear Derailleur system
The Shimano RD-M820 Saint RD+ Derailleur with its short cage design prevents chain slap and drops. Its low-profile build reduces impact damage, making it ideal for gravity racing. The Direct Mount system creates extra space around the dropout for easier wheel removal and improved frame design. A chain stabilising switch minimises chain bounce, keeping shifts crisp on rough terrain.
Key Features and Benefits:
- Shimano Shadow RD+ Short Cage: Prevents chain slapping and dropping. Keeps the drivetrain stable in demanding conditions.
- Direct Mount system: Increases rear dropout space for easier wheel removal. Allows frame designers to improve axle sizes, chainstay length, and suspension pivots.
- Low-profile design: Reduces exposure to trail hazards. Prevents derailleur damage for better durability.
- Chain stabilising switch: Engages to reduce chain movement over rough terrain. Improves drivetrain stability and maintains smoother gear shifts.
- Direct cable routing: Keeps cables out of the way of trail obstacles. Prevents snags and interruptions to shifting.
- All-alloy construction: Reduces weight while maintaining strength. Ensures long-lasting durability without adding bulk.
- Fluorine-coated link pin bushings: Reduce friction and resistance in shifting components. Enhances smooth, precise gear changes.
- High-rigidity wide outer link: Braces the pulley body to increase joint stiffness. Provides crisp, responsive shifting under load.
Built for gravity riders, this derailleur offers reliable shifting and chain stability under extreme conditions. The advanced design keeps weight low while improving strength and precision.
