Door Buster Stages Power Meter G3 Lr - Shimano Ultegra R8100 [limited Qty] [5UnNvpGO]

Built on either side of a Shimano Ultegra R8100 crankset, the Stages Power LR - Shimano Ultegra R8100 is seamlessly integrated, adding just 35g in weight and allowing normal functionality, while monitoring the force of each leg separately.

Power meters have long been a part of professional training programmes, but Stages was the first to extend training with power to the masses with its relatively inexpensive left sided power meter. Now, with dual measurement, Stages Power will help cyclists of all levels to achieve their full potential.

Individually calibrated, the power meters are accurate to +/- 1.5%, offering reliable data in an easy-to-fit, intuitive to use package that is compatible with Shimano drivetrains and built around the Shimano Hollowtech II crankset. Built-in temperature compensation and water resistance will ensure that, whatever the weather, you can trust your force data.

Stages Power LR - Shimano Ultegra R8100 will enhance your training programme, as it can be easily controlled and monitored through the StagesPower app and comes with free lifetime access to the Stages Link platform, with all its analytics tools, workouts and routes. It is also compatible with most other popular training apps or your Garmin bike computer, allowing you to link your results to Strava, Training Peaks and many other training tools.

Key features:

  • Independently measures the power of your left and right legs
  • Gen 3 Stages power technology with accuracy of +/- 1.5%, with a power range of 0-2,500w and a cadence range of 20-220rpm
  • Adds just 35g to base crank arm weight
  • Uses CR2032 coin call battery to give 150 hours of use
  • With water resistance rating of IPX7 and inbuilt temperature control
  • Crankset is compatible with all 12-speed Shimano Hollowtech II road bottom brackets
  • Device compatibility: ANT+, Bluetooth Smart Ready
  • Software compatibility: Stages Link, Training Peaks, Strava, Garmin Training Center and others
  • Comes with lifetime access to Stages Link for power meter management and firmware upgrades
  • Available crank lengths of 160, 165, 170, 172.5 and 175mm
  • Available chainring configurations of 50/34 or 52/36
