With its 9-speed drivetrain, powerful V-brakes and disc brake systems, as well as the Rapidfire Plus shifters, Alivio is the trendsetting group for high-quality recreational cycling. Key advantages include reduced susceptibility thanks to the flat design with 9-speed shifting systems, a tidy, compact, and integrated design, increased stiffness, and an aggressive look suitable for MTBs of all wheel sizes, quick installation and removal of the wheel through external B-Tension or Direct-Mount derailleur specifications, as well as clean cable routing with integrated aesthetics through the combination of hydraulic brake lever and shifter technologies. HG-Hyperglide: In combination with Shimano Hyperglide chains, the HG cassette sprockets guarantee fast, precise indexed shifting.
