Shimano Ultegra FC-R8100-P Power Meter Guarnitura 2x12-speed velocità 50-34T
Offering all the precision and functionality of the DURA-ACE power meter, the ULTEGRA FC-R8100-P power meter comes in a more affordable package.
Scientific training requires accurate measurement and user-friendliness, and the new ULTEGRA R8100 power meter has both. Its dual-sided measurement is accurate within 1.5% and zero offset calibration is a quick and easy process. Perhaps most importantly, its long battery life, easy recharge, and ANT+ and Bluetooth LE connectivity makes using and recording your workouts easier than ever.
HOLLOWTECH
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 lightweight.
HOLLOWTECH II
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. The HOLLOWTECH II crankset has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design.
High Precision Sealing
Moreover, HOLLOWTECH II crankset has a high-precision sealing in the bearing area to increase durability maintaining the excellent rotating performance for long periods.
