Shimano Alivio - Experience the 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 flat construction of 9-speed shift systems, a tidy, compact, and integrated design, increased stiffness and aggressive styling suitable for mountain bikes 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. In combination with Shimano Hyperglide chains, the HG cassette sprockets guarantee fast, precise index shifting.
