FEATURED TECHNOLOGY

HOLLOWTECH II
HOLLOWTECH II

Providing the best balance of stiffness, strength, weight and rotating performance
The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider's power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight a key element of the crankset you want light aids in cycling longer distances over which the rider needs to pedal more. Naturally SHIMANO strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank.
HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company's own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings toa chieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability allowing for more efficient power transfer.
The HOLLOWTECHII crankset has been developed by pursuing the optimum balance of stiffness &rotating performance in a lightweight and beautiful crankset design.
