The new wide-range drivetrain delivers precise shifting with single chainring simplicity and 9-speed durability. Rear derailleur comes with clutch for increased chain security and minimalized bouncing. With bombproof construction capable of handling the realest mountain bike abuse, Advent competes favorably with drivetrains that cost twice as much.
