Shimano Alivio FC-T4010 Crank Set Octalink 9-speed black

Shimano Alivio - Experience real MTB feeling!
The Alivio group offers a full range of sophisticated Shimano features. With its 9-speed drive, powerful V-brake and disc brake systems and Rapidfire Plus shifters, the Alivio is the trendsetter group for high-quality recreational mountain bikes.
The design of the Alivio crank has advantages: less vulnerability due to the flattest design in 9-speed shifting systems and a tidy, compact and integrated look. The increased stiffness and aggressive design is suitable for MTB of all common wheel sizes.

Octalink
Compared with the power transmission of OCTALINK with conventional square-butted spindle, the 8-tooth contact surface of OCTALINK, which connects the bottom bracket and crankset, increases the load capacity and stiffness of the entire assembly.

HG sprockets
The specially shaped HYPERGLIDE sprockets feature special tooth profiles as well as specifically positioned climbing aids that optimize chain guidance during shifting. This enables fast, precise index shifting.
