Description

Train smarter.

Maintaining a healthy balance between work, life, and cycling often leaves us more than a little crimped on training time, and haphazardly guiding those precious hours by finicky heart rate data just isn't cutting it anymore. It's time to step up the quality of your training time and swap out your standard Ultegra 6800 left crank arm for a Stages Cycling Shimano Ultegra 6800 Single Leg Power Meter Crank Arm. With a price point that pales in comparison to dual-leg systems, this meter measures power transfer through the left crank to deliver accurate, reliable power data while leaving some cash in the bank for recovery nutrition and mid-ride snacks.

The key behind this crank arm is the little power meter pod affixed to its inner face, which takes what originally was a standard Ultegra 6800 crank arm to the next level and adds the ability to gather pinpoint power data to better measure your ride. It utilizes a blend of strain gauges and an accelerometer to gather position and force data 64 times per second and deliver power readings with a claimed +/- 2% accuracy that's right in line with what we'd expect from any quality power meter.

For the gram counters out there, the Stages meter adds a miniscule 20 grams to the crank arm, which is a tiny concession to gain the massive data tracking and training specificity having a power meter affords. To put it in perspective, choosing the smaller safety pins the next time you don a race number should easily balance things out.

Stages Power for Ultegra

  • Familiarity: I've used it several times

Very impressed with the data I’m getting. Very easy to calibrate via iPhone app. I have a Garmin 500 which has limited data recording settings; 1s and smart recording. I use the 1s setting and my power profiles are not smooth. A better head unit for power that has 3s to 10s recording should be used. Back to the Stages. Installation was a breeze. Calibration was a breeze. Ant+ connectivity was a breeze. Have not used Smart Bluetooth, except for zeroing. Still on original battery so I can’t comment on battery replacement as another reviewer commented. But so far, I’m happy with the Stages. I have a Newton+ PM on my other bike and the numbers match up well. I’ve used the Stages for about a month and so far, it’s been giving me good numbers.

Stages Power for Ultegra

Stealth Power Meter

  • Familiarity: I've used it once or twice and have initial impressions

I don't like sensors on my bike, but I wanted power. This is the ultimate incognito way to get that at a reasonable price (without replacing my new Vision 40s). Easy to install, painless to operate, reliable data delivery.

Get something else

  • Familiarity: I've put it through the wringer

This worked perfectly until I needed to change the battery. Each time the battery has needed replacing, I have had to return the unit. I am now on my third replacement and this one did not work on arrival. Rubbish!

Great Power Meter

  • Familiarity: I've put it through the wringer

I have been using stages for a few years now. The newly redesigned sensor has been much more accurate and reliable. It is easy to sync up and calibrate before every ride. They offer and easy to use Smart Phone App to do any zero resetting or updates.

When it comes to data, it seems to be pretty accurate. In the end all power meters are going to read differently. If you use the same brand or type of power meter on all of your bikes, then you are going to have an accurate and consistent measurement to base all of your training off of. The stages arms are easy to switch between bikes if you have two bikes with the same type of crankset. The power meter only adds about 25 grams to the crankset, so not much added weight at all.
