TECHNOLOGIES
HOLLOWGLIDE - Hollow technology on outer chainring. High rigidity hollow structure cuts down on weight yet maintains strength. Better power transfer and quicker and more precise front shifting.
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 riders 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. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the companys 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.
