The Shimano FC-R8100 is a crankset that belongs to the new Ultegra group. It is compatible with all Shimano road groups in the 2x12 standard. Designed with Hollowtech II technology, it features an integrated crank spindle and hollow aluminum arms, which reduce weight, increase the overall structure’s stiffness, and are responsible for more efficient power transfer generated by the rider.

The chains are mounted via a four-arm, asymmetric spider, with no visible external bolts, improving aesthetics and aerodynamic properties. Additionally, Shimano Dura Ace R9200 group chains can be used. The precise and quick gear shifting will enhance the overall riding experience.

These particular features will be appreciated by road cyclists and triathletes, where fast mechanism operation is a critical factor.

Technologies: Hollowtech II – The best balance of stiffness, durability, low weight, and rotational performance. The stiffness of the crankset, thanks to the integrated bottom bracket spindle, ensures pedaling efficiency, while its weight supports riding longer distances. Naturally, Shimano aimed to achieve a total balance between stiffness and the lowest possible crankset weight. The use of their own forging technology on the ultra-light crankset provides stiffness. The external bottom bracket bearing system offers better weight distribution, increased pedaling stability, and more efficient power transfer, all in a lightweight and sleek design.
