Saint Shadow rear derailleur, low profile, super wide link, super tough, this is a must have component for any gravity rig. Shadow design with smooth skid plate surface features a super low profile design that reduces the risk of damage from trail side hazards. Using a mode converter on the body this rear derailleur works with cassette ratio of 11-23 to 11-28 tooth, or 11-32 to 11-34 tooth. Single tension spring prevents contact with the chainstay resulting in a silent ride. Direct cable routing prevents snagging from any trail side hazards. Cold forged alloy links and pivot body's 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. Super wide link gives awesome rigidity, bracing the mech body to increase pivot joint rigidity resulting in a crisp shift. Strong return spring for a positive shifting feel. Mega9, 8 & 7-speed compatible. Durable Ceramic bush and sealed bearing pulley wheels. Top normal spring uses the spring to select higher gears, best suited to use with Rapidfire shifters. For double ring use with a total capacity of 31 tooth, or 37 tooth with mode converter in.
