Accurate Readings in all Conditions Shimano have extensively tested this new power meter system to ensure its accuracy and reliability in all weather conditions. The chainset is equipped with dual sided and internally hard-wired crank arm strain gauges, which provide a ±2% power measurement accuracy regardless of your pedalling position. Easy to Maintain The power meter is powered with a simple rechargeable battery for easy maintenance and can be updated wirelessly. As it is mounted to the crank arms 4-arm spider, you can change the chainrings without having to worry about affecting the power measurement. Lighter and stiffer Although the crank arms and spider arms are noticeably bigger to increase stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. This Compact version features a 50/34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.
All set for a top-level experience, this superb component features a tough alloy construction which makes it immensely durable as you pedal. Coming equipped with a revised design, this sleek version delivers an iconic appearance which is adapted for race-specific disc brake systems while still offering a wide gear ratio. Rechargeable Waterproof Power Meter Engineered for all-weather conditions, this brilliant model is equipped with a waterproof finish which means you can enjoy accurate data result in the wettest of riding conditions. With an integrated rechargeable battery at its heart, you'll benefit from up to 300+ hours of pedalling precision. This means you can spend less time waiting for it to charge and more time enjoying the ride.
A vital tool for serious cyclists, the Dura-Ace FC-R9200-P power meter delivers reliable, waterproof, dual-sided power measurement. With a rechargeable battery and Bluetooth LE and ANT+ connectivity, the FC-R9200-P is a user-friendly training partner. Bluetooth LE and ANT+ Connectivity The Dura-Ace FC-R9200-P 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. The Shimano Dura-Ace R9200 12 Speed Power Meter has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design.
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.
