Show Description

Cyclists looking to make serious gains will appreciate the consistency and accuracy of this dual-sided power meter. Based on the latest Ultegra R8000 crankset, the Stages Dual-Sided power meter allows for independent measurement of a rider's left and right legs, measures pedal smoothness and, most importantly, helps you reach your goals.

This unit is as low-profile and lightweight as a power meter gets – 35g – with a minimalist housing and sleek front profile. You can expect wattage readings to be accurate within 1%. ANT+ and Bluetooth Smart compatibility lets it link up with pretty much any major GPS or cycling computer on the planet. The compact, easy-to-source coin cell battery's life is over 175 hours, and you can swap it out yourself.

  • Comes pre-mounted to Shimano's Ultegra FC-R8000 crankset.
  • Fully sealed unit with IPX 7 waterproofing.
  • LED indicator displays battery level at startup and confirms successful calibration.
  • Left and right meter can be used separately by unpairing them in the Stages app.
  • Power is measured in kilograms via strain gauge and mathematically converted to Watts.
  • Active temperature compensation allows accurate readings regardless of weather.
  • Accelerometer-based cadence readings keep your bike free of wires, magnets, zip-ties and other hardware.
  • Specifications: accuracy: ± 1%, power range (Watts): 0 to 2500, cadence range (rpm): 20-220.
  • Wireless firmware upgrades keep the unit future-proof.
  • Upgraded ANT+ and Bluetooth Smart offers 6x stronger data transmission signal.
  • Software compatibility: Stages Link, Training Peaks, Strava, Garmin Training Center and others
  • CR2032 battery lasts 175+ hours and is user-replaceable. Drive side requires a Phillips screwdriver while non-drive side is tool-free.
  • Fits most bike frames; check Stages fit guide for details.
