The 105 FC-5800 crankset by Shimano - highly flexible and efficient

With the 105 FC-5800 crankset, Shimano now also equips its mid-range Road bike groupset with an 11-speed compatible 4-arm crank. As with its big sisters Dura Ace and Ultegra, this innovative design ensures an ideal stiffness/weight ratio and highly efficient power transmission. Several chainring combinations can be installed on the standard 110 mm bolt circle, which provides more flexibility than with the 105 cranks previously. The FC-5800 has hollow forged aluminium arms (Hollowtech) and naturally comes with Hollowtech II technology, which ensures a perfect symbiosis of minimal weight and maximum strength.

A lightweight crankset not only reduces the bike's weight, but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the Hollowtech crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very light weight.

Hollowtech II
What matters is the overall balance of the crankset. With regard to the entire crankset, an optimum ratio between the strength of the crank arms, the stiffness of the axle, the bearing position and other features is very important. During the development of the crankset, the overall balance of all individual elements was carefully considered in order to ensure maximum stability.
Outer bearing: On most 68 mm bottom bracket housings, the Hollowtech II 24 mm axle can be mounted outside the frame for better weight distribution and stability.
High-quality precision seals: The Hollowtech II set also features high quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over time.
The axle and the 24 mm diameter bearings ensure optimum balance of the crankset and optimum transmission of power to the bicycle.
