SHIMANO is probably one of the most famous and popular manufacturers of quality bicycle parts and accessories in the world. Parts from this manufacturer are more or less used in most of the bicycles Founded in 1921 in Japan, the company currently has perhaps the widest range of products for both amateurs and professionals. Every year, innovations are introduced that allow cyclists to shift gears more precisely, brake more efficiently or finish the track faster. Currently the company is expanding the offer of electronic gear shifting mechanisms and electric bicycle parts more and more. The range of products is not limited to bicycle parts, clothing for cyclists is offered as well.
SHIMANO's new FC-RX810-2 crank balances weight and efficiency for mixed-terrain riding. Gearing options cater for the specific demands of gravel riding and to maintain tighter gear steps for maintaining pedaling rhythm. The 2x11-speed crank is available in a 48-31T chainring combination and 170, 172.5, and 175mm crank arm lengths.

TECHNOLOGIES
HOLLOWTECH II 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. 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 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.
