The hard-ACE FC-R9200, the heart of the bicycle, ensures that no element of your ride is wasted. With the cavity and the cave crops, the weight is maintained at a minimum, but the rigidity and precision of the gearbox are maximized.
The hard-ace FC-R9200 crankset performs two vital functions: transfer your pedaling effort to the transmission and offer the faster and more precise change of crown available. With the lightness of the Hollowtech II cran down and the high-end design of the Shimano crowns, the FC-R9200 will never disappoint you. The FC-R9200 is offered with even more short pedagles to ensure perfect adaptation to any cyclist.
CHARACTERISTICS
Technologies
Hollowglide
Cava technology on the external crown, the high -rigidity quarry structure reduces weight keeping stiffness unchanged. More efficient power transfer and more immediate and precise change of crown.
Hollowtech
An ultralight clumsy not only reduces the weight of the bike, but also reduces the rotation mass, facilitating accelerations. The goal is to reduce the weight of the crankset without reducing their robustness and rigidity. The advanced shimano forging technology has solved the problem with the Hollowtech crack. As in the case of high -quality frame tubes, a quarry tank can guarantee incredible robustness and rigidity with a very low weight.
Hollowtech II
A perfect balance between rigidity, robustness, weight and efficiency. Hollowtech II technology is aimed at the production of a higher cracking, capable of maximizing the transfer of power. The rigidity of the garnishing guarantees efficiency in the pedaling, while lightness, a key element of the crankset, facilitates the cyclist on long distances, where it is necessary to pedal more. Of course, Shimano has committed himself to the maximum to ensure superleggerara and extremely rigid cracking, two objectives in conflict with each other. The Hollowtech technology, which consists of an ultralight quarry caval that maintains stiffness unchanged, was developed by Shimano with the use of its exclusive forging technologies. The addition of the Hollowtech II technology integrates the axis of the central movement with the right pedestral, ensuring greater rigidity, a reduction in weight and high dimensional stability. The axial bearings system of the central movement guarantees a better weight distribution, which translates into a more efficient transfer of power. The Hollowtech II crankset was developed pursuing an optimal balance between stiffness and rolling performance, and so an ultralight and very elegant design was obtained.
