Using a power meter is one sure-fire way to train more efficiently, ride faster and achieve a podium topping performance. While previously, power meters remained the reserve of professional riders, thanks to the new 4iiii Precision 2.0 3D, training with power is more accessible than ever before.
Unlike other, bulkier units, this power meter weighs just 9 grams and fits so neatly onto the inside of a regular Ultegra 6800 crank arm; you'll barely notice that it's there. Using 3D patented technology, the 4iiii Precision 2.0 3D measures your power output to +/- 1% accuracy, via the tri-axel strain gauge. This degree of accuracy means you can train with much more consistency and ultimately, achieve much better results. With an easily replaceable 2032 coin-cell battery, this power meter offers 100+ hours of riding time and, like a rechargeable battery, can easily be checked for life using the dedicated 4iiii companion app. Thankfully, the 4iiii Precision 2.0 3D is compatible with most ANT+ and Bluetooth capable devices and apps. So, whatever computer, training device or apps you use, you won't need to worry about integration between your new power meter and your current set up.

I like
Seems to work well. Pretty similar results to caculated average results for a ride from Strava. Simple installation (replace crank arm) and price is very good via PBK
Power Meter
Works really well. Good right out of the box, just have to calibrate it and off we go.
Great for the price
This is the second one I've owned. The first one ran perfectly for about three years and then started giving funky high readings. Advantages are: Great battery life, good design for battery compartment (waterproof), temperature compensation, signal to head unit never fails. Easy to pair. It is single sided so it just doubles the left leg. But it allows you to perfectly gauge your efforts since you really only need to compare yourself to yourself and a singlecsidecsuffices for that. I have owned Stages units too. I like these better because less susceptible to water, easier to install battery ( Stages o ring easy to lose) and more robust signal to head unit. I can't compare to other types of PMs. I can see even recreational riders can improve their riding with a PM.
4III Power Meter
The 4III Precision 2.0 3D power meter has worked flawlessly for me. I have had no issues in rain intrusion or with the battery life in the 275km of use so far. The power meter zero's with no issue and transmits data to the wahoo app on my android phone. Overall I'm very happy with the power meter especially at the price point here on PROBIKEKIT.
4iiii ultegra 6800 175mm
Excellent price value. Delivery is fast, 3 days to Hungary. The power meter is quick to install, and works well with garmin headunits and bluetooth android applications. The item in it was only 48% in condition, I had to replace it, but they gave another in the package. Recommended category who wants to train at a good price based on performance.

Simply works
Easy to install and easy to pair with the Garmin. Works straight out of the box. So far have ridden the unit 5 times and power readings were consistent without and drop in the readings.
4iiii Simply Works
Great price on a 4iiii Ultegra left crank arm power meter. Easy to install and pair with a Wahoo Bolt. Simple, quick pre-ride calibrations. Consistent readings on tarmac and gravel. Smallest and lightest sensor of all left crank arm power meters. If you want basic power data during and after your rides, this product is hard to beat.
Game Changer
This has totally changed my winter training. I can target specific training both indoors and outdoors. Easy to fit and set up.
