The SHIMANO T4010 crank offers a wide 3 x 9 speed gearing range and uses an OCTALINK bb interface. Hyperdrive system components work together to improve chain control to provide precise and reliable front derailleur shifting that is especially beneficial in severe off-road riding conditions. Octalink bottom: Compared the power transfer of OCTALINK with the conventional square taper spindle, the 8-splined OCTALINK interface that connects bottom bracket and crank set increases the strength and rigidity for entire assembly. The distinctively designed HYPERGLIDE sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result.
