Shimano Xt M771 Rear Derailleur

This is an XT rear derailleur that is Mega9 compatible for use with 9-speed drivetrains and delivers reliable and precise shifting with a stiff and lightweight open design.
It has a Top normal spring that uses the spring to select higher gears. This is best suited to use with Rapidfire shifters or it can be combined with Dual Control levers.
It has an all-alloy construction, that leads to lower weight without compromising strength and durability, and four fluorine-coated link pinbushings that make this one of the slickest shifting derailleurs on the trails.
