Shimano 105 Crankset 2 x 12 speed

The newly designed crank arms offer an optimized balance between lightweight and efficiency. The crank, formed with hollow aluminum technology, is anodized with a beautiful gloss black anodized finish, giving it a luxurious look. The resin ribs on the back of the chainrings are SHIMANO 105's unique structural design that achieves both thorough weight reduction and crisp shifting performance. 

FEATURES

HOLLOWTECH II

Providing the best balance of stiffness, strength, weight, and rotating performance, the HOLLOWTECH II concept focuses on producing a superior crankset that maximizes a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency, while its weight, a key element you want to be light, aids in cycling longer distances where the rider needs to pedal more. Naturally, SHIMANO strove for the optimum balance between the conflicting needs of stiffness and lightweight crank design. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO using the company’s proprietary forging process, which 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 greater pedaling stability, enabling more efficient power transfer.

The HOLLOWTECH II crankset has been developed to achieve the optimum balance of stiffness & rotating performance in a lightweight, beautiful design.

High Precision Sealing

Moreover, the HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability, maintaining the excellent rotating performance for long periods.
