Technologies

HOLLOWGLIDE
High rigidity hollow structure reduces weight but maintains strength. Better power transfer and faster, more precise front shifting

HOLLOWTECH
A lightweight crankset not only reduces the weight of the bike, it decreases rotating mass to aid acceleration. The challenge is to reduce the weight of the connecting rods without reducing their strength and stiffness. SHIMANO's advanced forging technology has solved the problem with the HOLLOWTECH crank. Like high-quality frame tubes, a hollow crank arm can provide amazing strength and stiffness at a very low weight.

HOLLOWTECH II
The HOLLOWTECH II technology concept focuses on producing a superior crankset that maximizes the transfer of power to the rider. The stiffness of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, which is wanted to be light, helps to cover longer distances where the cyclist needs to pedal more. HOLLOWTECH technology is an ultra-lightweight hollow crank created by SHIMANO using the company's own forging technology that also maintains stiffness. The addition of HOLLOWTECH II technology integrates the bottom bracket spindle with the right crank for increased stiffness and weight savings for high-dimensional balance. Its outer bottom bracket bearing system provides better weight distribution and more stability while pedaling, allowing more efficient power transfer.
The HOLLOWTECH II crankset has been developed to find the optimal balance of stiffness and turning performance in a beautiful, lightweight crank design.
