HOLLOWTECH II: The best balance between stiffness, strength, weight and turning performance The concept behind HOLLOWTECH II technology is to produce a superior crankset that maximizes the transfer of power from the rider. The rigidity of the crankset ensures pedaling efficiency, while its weight - a key element of the crankset, which is intended to be light - helps to cover long distances over which the cyclist needs to pedal more. Naturally, SHIMANO has endeavored to strike an optimum balance between the conflicting needs for rigidity and the production of a lightweight crankset. HOLLOWTECH technology is an ultra-light hollow crank arm created by SHIMANO using the company's proprietary forging technology, which also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the straight crank arm for added rigidity and weight savings to achieve high-dimensional balance. Its external crankset bearing system ensures better weight distribution and greater pedaling stability, enabling more efficient power transfer. The HOLLOWTECH II crankset has been developed with the optimum balance of rigidity and rotational performance in mind, in a lightweight, handsome crankset design. High-precision sealing, De pl
