L'Scientific training requires accurate measurements and ease of use, the characteristics offered by the new Potenza meter Ultegra R8100. The measurement on two sides has a max waste of 23.0% and zero calibration is a quick and easy procedure. Perhaps even more important is the long battery life, easy charging and ant+ and bluetooth®le connectivity that make L'use and recording of training easier than ever.

Technologies
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 crankset guarantees L'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 pipper that keeps stiffness unchanged, was developed by Shimano with L'Use of its exclusive forging technologies. L’Addition of the Hollowtech II technology Integrate L'Central movement axis with the right handle, 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.
Hollowtech Crank Arm
Cave forged caves. An ultralight clumsy not only reduces the weight of the bike, but also reduces the rotation mass, facilitating accelerations. LThe goal is to reduce the weight of the crankset without reducing their robustness and rigidity. LAdvanced forgiege technology Shimano 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.
Hollowglide
The high -rigidity quarry structure reduces weight keeping resistance. Best transfer of power and faster and more precise front gearbox.
