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

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

Nauwkeurige en dubbelzijdige metingen maar niet waterbestendig

Hele nauwkeurige metingen die het trainen gemakkelijker maken. Helaas is de linkerarm niet waterbestendig en heb ik die moeten afplakken, zodat die niet kapot roest

Pros

  • Dubbelzijdige metingen
  • Nauwkeurige vermogens
  • Meting pedaalsoepelheid
  • Makkelijk updaten

Cons

  • Niet waterbestendig

Get this is you want to improve

I replaced my old 6800 crankset with this new R8000. I did the whole work myself, it took me about 1 hour. You'll need just a couple of allen keys, a crank cap tool and a torque wrench. I did not have to replace the front derailleur so that's great. So far I am very satisfied with this product and if you have the money, don't think twice and get it. I'll not repeat here what's already known about training with power. Personally the greatest advantages I see are: - be able to pace yourself better on climbs - be able to follow training programs with power - make indoor training less boring and more similar to an outdoor ride. - know about my L/R balance and pedaling efficiency

Pros

  • Easy to install
  • Easy to setup
  • dual side

Installing the Shimano Stages power meters is easy. You just need a torque key and a crank puller.
