Technologies

Hollowtech 2
24mm Diameter Axle

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 to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.

HG-EV
HG-EV cassette sprocket is obtained 11-speed gear without compromising the 10-speed durability and improved HYPERGLIDE shifting.
