Stages Shimano 105 5800 Power Meter

Compatible with all Shimano Hollowtech II road cranks, the Stages Shimano 105 5800 Power Meter replaces your current left-side crank arm. Like all Stages power meters, this unit features +/- 1.5% accuracy, 200 hours of battery life and is lightweight at only 20 grams of added weight. In addition, the power meter is compatible with both ANT+ and Bluetooth SMART devices. This means you can use a bicycle computer with ANT+ or your smartphone or tablet with Bluetooth SMART.

The new Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy and have an LED indicator light on the housing for improved ease of use.



Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm

    I’m enjoying this power meter thanks to power meter city great customer service and appreciation of customer loyalty. This is my second power meter from them and they were kind enough to upgrade my shipping option in an exchange for an honest unbiased review of my first power meter.

    Excellent service with speedy response to query. The reason why I bought from PMC is because they took the effort to address my query on whether or not this would fix on any other Shimano hollowtech two cranks within a day!

    I’ve happily received the unit after a few days of placing my order (am in Asia) and I can’t be happier with their service. On top of that, free shipping for this unit!

    Guys, these dudes really deserve our business!

    Really enjoying finally getting Watts data with my fantastic Stages 105 5800. Communication from PMC and international delivery from DHL was first class. The installation was simple with a little help from Youtube and the calibration was straightforward. I have no hesitation in recommending PMC to anyone thinking about adding power metrics to their training data.

    I have been wanting a power meter for awhile. I finally pulled the trigger and I am very pleased. The pricing was great and arrived in short order. I also had a few questions about the power meter and its set up on my bike. I emailed PMC several times and got my questions answered either that night or first thing in the AM. I will do business again.

    I have decided to get into powermeter training as the local cycling open circuit gets really windy and with PM prices getting down its time. Powermetercity chat guy was really knowligible and helpful, you really need that, the experience was fantastic and flawless. The stages 3rd gen itself is the third itteration, its mature to the level that you just forget its there ! Power data now is taken for granted on my wahoo element and Garmin finex 5 / Training peaks.
