Thanks to the new 4iiii Precision 2.0 3D power meter, training with accurate power data doesn't have to cost the earth. Finally, anyone can train harder and ride faster for a podium topping performance. 4iiii claims that the Precision 2.0 3D unit is the lightest power meter on the market, perfect for those chasing every marginal gain. Weighing just 9-grams and fitting so neatly on the inner side of the standard Shimano 105 5800 crank arm; you'll barely notice it's there.
Inside the unit contains the patented 3D technology, which measures your power output to +/- 1% accuracy, via an axel strain gauge. Because of this high level of data accuracy, the 4iiii Precision 2.0 3D allows you to train with much more consistency and achieve the best possible results. Powered by a replaceable 2032 coin-cell battery, the Precision 2.0 3D contains 100+ hours of riding and can easily be checked for remaining battery life via the dedicated 4iiii companion smartphone app. 3rd party training device and app integration are endless. As you can pair this power meter with almost every ANT+ or Bluetooth head-unit, trainer or training app, there's no need to worry about the compatibility of your new power meter with your current equipment set up.

The product arrived flawless in it's box as a 4iiii precision meter bonded nicely to a new 105 5800 crank arm. It came with a battery pre-installed and an extra battery wrapped to the packaging. Following the easy step by step instructions on the box it paired immediately with my Garmin 530 and has worked without fail. Great product!
Bought one from PBK last year. No problems at all. It's reliable, stable, light, sealed properly and delivers consistent results. Battery life is also very good. I had previous experience with Stages gen. 2 and in my opinion 4iiii is superior to Stages. For the price there's no better powermeter for Shimano users. Highly recommended.
This is my second 4iiii power meter. I was in on the original kickstarter offering, and mailed them my crank arm for installation. Works great, no issues. Seems to have better battery life than my Stages. Tested the first one against my Power Tap hub, and they numbers were very close. Highly recommended.
Got it at very affordable price. Easy to install, calibrate. Did few outdoor ride and Zwift session, it work just great! Highly recommended.
Easy to install, calibrate and pair to (lezyne) head unit and Zwift via bluetooth. Works as expected. No power drops. 6 days tracked shipping to Canada. Paid tax and handling.
Everything works well, Data are precise, no drops out, Extremly fast shiping to Slovakia (2days) 100% recomended
Easy to fit easy to setup. Works very well. Data collection seems to be nice and stable to both Strava and Garmin. Great product and great service would recommend both probikekit and 4iiii power meter crank to anyone
I have no problems with 4iiii after 2 months of use. Highly recommended.
It’s very good cost effectiveness also performance too Recommend 4iiii powermeter
got on offer a few months back. great PM and very easily swappable if you run Shimano cranksets on all bikes as i do. never misses a "watt" and is comparable in power output to my Vector S. we'll see what its like in the next few months with lower temps, etc but all is good so far. had a question for support re calibration and they reverted very quickly.
