Description

The Stages Ultegra R8000 L/R cranks are a precise double-sided power meter. The double-sided power meter has been tested for more than two years by Team Sky and Chris Froome, the winner of both the Tour de France and the Vuelta d'espana in 2017. The Stages Ultegra R8000 L/R also measures the smoothness of the pedal rotation and the torque to yield. The Stages Ultegra R8000 L/R is a perfect fit in the Stages Performance Ecosystem combined with the Stages Link software and the Stages Dash cycling computer.

Left and right are measured by separate sensors and can be used independently. This enables you to for example mount the right crank on one bike and the left crank on another. If you use both crank arms on one bike, you get a double-sided power meter. Thanks to Active Temp Compensation (ATC), a precision of +/-1,5% at 100 watts and 90 RPM is achieved. The Stages Ultegra R8000 L/R is water resistant and has an IPX7 certificate. Both power meters have a CR2032 battery which lasts for about 175 hours.

Fantastic Tool for data about riding & training

This has changed how i look at every ride. My riding style is now analyzed in ways that were not possible before. I no longer ride & train looking at heart rate only. I now have real targets and tools to improve my power & watt per kg next season. I will also split across 2 bikes over winter for indoor & outdoor use as single sided. The product is not cheap but over time will be worth it.

Pros

  • Dual Sided
  • Easy To Set Up
  • Easy to use App
  • Can split across 2 bikes if necessary.

Cons

  • Price

Potenziometro di grande precisione.

Facilità d'uso, grande durata della batteria e un'ottima precisione del potenziometro che può essere settato con diversi accorgimenti. Un ottimo articolo sicuramente ad un prezzo elevato nella gamma dei sensori di potenza ma con prestazioni molto elevate.

Pros

  • Precisione
  • Durata della batteria
  • Diverse opzioni di settaggio
  • Velocità nel riconoscimento del Bluetooth

Cons

  • Costa elevato

werkt prima.

Geeft uitstekend aan wat het wattage is, waardoor ik gerichter kan trainen. Wat ik wel jammer vind is dat ik na iedere fietsrit de stages moet resetten, anders kloppen de wattages de vlg keer niet.

Pros

  • snel installeren
  • prima overzicht op m'n wahoo

Cons

  • na elke rit resetten

The data transfer takes place via ANT+ or Bluetooth Smart technology, which means almost all cycling computers can be connected. You can also easily conduct wireless firmware upgrades via your mobile phone.The internal accelerometer measures RPM wirelessly and without requiring additional sensors.

Installation of the Stages power meter

Installing the Shimano Stages power meters is easy. You just need a torque key and a crank puller.
Please note: Check whether the power meter is compatible with a direct mount rear brake below your bike’s bottom bracket.
