Product Details

Description

The Shimano Ultegra FC-R8100 Power Meter Crankset is an integrated power meter crankset for accurate, real-world training and performance tracking. It captures power and cadence data independently for the left and right leg, using an optimised accuracy of ±1.5 percent, and is designed to stay reliable without being affected by conditions like incline, road surface, or wind. Built around Shimano Hollowtech II crank technology and Hollowglide chainring design, it delivers efficient power transfer, confident stiffness, and smooth, precise shifting. It is a great match for 2x12-speed road riding when you want dependable metrics and race-ready drivetrain feel.

Key Features

  • Integrated left and right power measurement
  • Optimised accuracy at ±1.5 percent
  • Bluetooth and ANT+ connectivity
  • Hollowtech II stiffness and efficiency
  • Compatible with Shimano 12-speed road drivetrains

Accurate training data, side-by-side

Measure left and right power separately, so you can spot imbalances and refine your technique. Cadence readings help you dial in effort consistency on every ride.

Reliable measurement in changing conditions

The design reduces the impact of external factors, so your numbers stay stable when the terrain gets messy. That means more confidence when comparing sessions and building form.

Race-level Shimano shifting feel

Hollowtech II crank construction supports stiffness and rotational efficiency, while Hyperglide+ compatible drivetrains keep transitions crisp. Ideal for riders chasing faster times or smoother cadence changes.
