Shimano Ultegra R8100 12 Speed Power MeterThe Ultegra R8100 12 Speed Power Meter from Shimano is the ideal chainset to track your cycling performance output. It features Hollowtech II crankarms, a Hollowglide outer chainring and an ultra-precise integrated power meter. This top-quality power meter provides 1.5% strain gauge accuracy and up to 300+ hours of battery life, so you can accurately record your power output as you ride. And it's compatible with ANT+ and Bluetooth LE to communicate with your favourite cycling apps and computer software.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 BluetoothLE connectivity make using and recording your workouts easier than ever. Bluetooth LE and ANT+ ConnectivityThe 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 TechnologyHollow 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 ArmsA 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 WeightThe 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.

Front and rear bolt-thru axles keep the handling predictable and contribute to the responsive feel and efficiency, especially when you are out of the saddle and working hard up the climbs. Dropped seat stays complete the modern look and allow for a touch more comfort through the seatpost on those longer rides. Disc brakes not only equip you with precise control but allow the frame to afford wider tyre clearance of up to 32mm. This Zenium CRS model is finished with Shimano's well-proven Ultegra mechanical groupset, so you can trust that the gear shifting will be smooth and reliable. Cables are routed internally through a neat port in the downtube, protecting them from dirt and prolonging the performance of the components.
