Shimano Alivio

Shimano Alivio is a 9-speed drivetrain and sits in the middle of the line-up. Lighter and with slightly better shifting than Acera and Altus, the Alivio is seen on many popular mountain and hybrid bikes. Recommended by Shimano for recreational use, Alivio is only one step down from the Deore and XT drivetrains featured on more specialist bikes.
