Description

Scientific training requires accurate measurement and user-friendliness, and the new Ultegra 8100 power meter has both. Its dual-sided measurement is accurate to within 2.0% 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.

Features

  • Accurately calibrated strain gauges are integrated inside the crank arm, which provides a stable measurement system through rotation from both sides for exact data
  • +/-2% accuracy of strain gauge measured power
  • Bluetooth and ANT+ with wireless firmware update and data acquisition system
  • Easily rechargeable integrated battery with a fully waterproof, reliable electric system
  • HollowGlide hollow outer chainrings greatly improve rigidity by virtually eliminating outer chainring flex and hugely improve shift performance, even under high load.
  • The chainring teeth have been developed to work in conjunction with 12-speed HG chains, providing increased contact for greater efficiency and improved power transfer.
  • Industry-leading HollowTech II cold forged 4-arm hollow cranks evolved for maximum rigidity while reducing weight.
  • Wide gear pitch spacing increases clearance between the chain and the leading teeth to provide compatibility with O.L.D. 135 / 142 mm frames.
  • A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines.
  • HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency.
  • HollowTech II integrated bottom bracket seal design has minimal bearing interface, ensuring smooth rolling and increased durability(sold separately)
