Shimano Alivio - Experience true MTB feeling. The Alivio group offers a complete range of advanced Shimano features. With its 9-speed drivetrain, powerful V-brake and disc brake systems, as well as the Rapidfire Plus shifters, Alivio is the trendsetting group for high-quality recreational mountain bikes. Key advantages include reduced susceptibility due to the flat design of the 9-speed shifting system - tidy, compact, and integrated; increased stiffness and aggressive design suitable for MTBs of all wheel sizes; quick wheel installation and removal through external B-Tension or Direct-Mount derailleur specifications; tidy cable routing, compact design, and integrated aesthetics through the integration of hydraulic brake levers and shifters.
