Training with power is one sure-fire way to ride faster and achieve a podium topping performance. While previously, power meters remained the reserve of the elite, 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. Fitting so neatly onto the inside of a regular Ultegra 8000 crank arm, you'll barely notice that it's there. Through measuring your power output to +/- 1% accuracy, via the tri-axel strain gauge, the 4iiii Precision 2.0 3D allows you to train with 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. 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.
- Lightweight, 3D technology equipped power meter

Efficient and well priced
This is the second one of these I have owned ( I sold the last one with my last bike). For a single sided unit it is very good and also for the money as they are well priced compared to others. Its within 2 watts when I compare it to my smart trainer etc and syncs seamlessly to my head unit. Overall I'm very happy with it and would recommend it to anyone who is looking for a good entry into power meter based riding and training.
Just back from the first ride. Sooo satisfied. Easy installation, calibration and pairing also with my Wahoo ELMNT bolt. Working like a charm,. The only thing is Strava stupid calculation which never the less using their algorithm and ignoring data from power meter ... But who cares for Strava politics. Strongly recommend, the best option for pristine PM on the market!
Quick reliable delivery, easy to fit and working well. Love the stats!
19 months of perfect power performance
Long term review: Bought this tbh as it was the cheapest proper power meter available at the time. It has been amazing. Accurate against my Tacx Neo smart trainer within 5 Watts. Batteries last a couple of thousand km. Never drops the connection to my Garmin Edge 820. Made pacing an Everesting much easier.
Probikekit had the best price for this 4iiii R8000 power meter. It's the first time I have used it and found it very handy at pacing my rides, especially on climbs. They say the accuracy of the unit is very good but since its my first power meter I am not too bothered as the readings are solely for myself to help me pace my efforts. I guess, that's the main use of a power meter anyway so no need to spend any more for double sided ones. And stay clear of the stages power meters that's what I've been told. 4iii is, the one to buy!
Simple to fit, even easier to calibrate, working great, no power drop outs.
Great serive great prices.
I have just acquired a single sided 4iii ultegra power meter. I have only used it on a few rides but so far so good. First time I have used a power meter. The service from ProBikeKit was as good as always , ordered delivered within a couple of days and a very competitive price.
