Campagnolo Athena Power-Torque Crankset 3x11

Technologies:
Q and U factors: one of the lowest Q factor in the triple crankset segment today lets the rider maintain an extremely natural position for the knee and ankle when pedalling, while a U factor of 12mm ensures maximum comfort and freedom of movement.
Power-Torque™ system: System with single axle designed to maximize stiffness and power transmission.
XPSS™: Exclusive design of the eight upshift zones and two downshift zones of the chainring. The specific profile of the teeth and the zones dedicated to upward and downward chain movement enable fast and precise shifting in all conditions.
Hollow aluminium crank: superlative lightness.
