Shimano Alivio - Experience a real MTB feeling! The Alivio group offers a full range of advanced Shimano features. With its 9-speed drivetrain, powerful V-brake and disc brake systems, and Rapidfire Plus shift levers, the Alivio is the trendsetter group for high-quality recreational mountain bikes. Significant advantages include less susceptibility due to the flattest construction with 9-speed shift systems, a tidy, compact and integrated design, increased stiffness and aggressive design suitable for MTBs of all wheel sizes, quick installation and removal of the wheel by external B-Tension or Direct-Mount rear derailleur specification, and tidy cable routing with integrated optics by combining hydraulic brake lever and shift lever technologies. HG-Hyperglide: In combination with Shimano Hyperglide chains, the HG cassette sprockets guarantee fast, precise index shifting.
