Shimano Alivio Triple Crankset for Mountain Biking

Engineered for precision mountain biking performance, this 3×9-speed crankset delivers reliable power transfer and buttery-smooth gear transitions on technical trails or steep climbs. The triple-chainring configuration (44/32/22T) paired with Shimano’s Hyperglide technology ensures precise chain engagement across all gears, minimizing derailment risks during aggressive riding.

Key Features:
– Dual BCD Design: Outer/middle rings use 104mm BCD for enhanced torque handling; inner ring features 64mm BCD for lightweight agility
– Octalink V2 Spindle: Shimano’s optimized interface reduces stress concentration points by 30% compared to standard square taper designs
– 135/142mm Chainline Compatibility: Perfectly aligns with modern MTB rear hubs for vibration-free pedaling
– 175mm Crank Arms: Ideal length for maintaining pedaling efficiency during long rides or downhill maneuvers
