Offering all the precision and functionality of the 12-Speed Shimano 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 make using and recording your workouts easier than ever. Bluetooth LE and ANT+ Connectivity The Ultegra R8100 Power Meter brings everything a data-driven cyclist could want. Its integrated, waterproof design brings all-weather reliability while delivering accurate information including left/right balance. A rechargeable Li-ion battery is user-friendly and Bluetooth LE and ANT+ connectivity ensure easy setup. Hollowglide Chainring Technology Hollow technology on the outer chainring. The Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance. Hollowtech II Forged Crank Arms 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. The Best Balance of Stiffness, Strength and Weight The concept of Hollowtech II technology is focused on producing a superior crankset that will maximize a rider’s power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which the rider needs to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.
