I’ve used a 4iiii PRECISION 3+ energy meter for a while, however by no means the twin model of any of their meters. The out-of-the-box presentation is charming. The unit is available in a 4iiii customized field with some easy-to-use set up directions and is well-packaged.
I acquired the Utegra 12-speed R8100 model with a 52×36 setup. The drive-side energy pod is positioned on the crankarm and snakes close to the middle of the crank.
The pressure gauges don’t cowl the complete internal bolt. The 4iiii pod attaches to the crankarm and hides properly behind the big chainring.
Three small Philips head screws maintain the battery cowl on, and it’s in a slight triangle form with the 4iiii emblem.
Set up — 4iiii PRECISION 3+ PRO
The set up is as straightforward as putting in a Shimano crankset.

Ensure that to hook up with the 4iiii app, do a zero reset, and replace to the newest model. The 4iiii app is a pleasant software for managing the meters and making certain their well being.

Concerning energy readings, the 4iiii was on par with my Quarq and single-sided 4iiii unit. It responds effectively in real-time, and I haven’t needed to clear up any energy spikes in knowledge afterward. All the things appears clear and constant, however there’s extra to come back in a long-term evaluate later this spring.
4iiii Apple Discover My Integration
I used to be very excited in regards to the Discover My integration and never having to make use of an Air Tag on my bike. This function might be tremendous useful, not solely as a “The place’s my bike” if it will get stolen. It may be used for touring, ensuring your baggage (bike) will get on the aircraft, or checking the standing of the bike in entrance of the cafe’. It’s some further peace of thoughts.
The setup was easy and solely required a number of further steps past putting in an AirTag. The ability meter unit must be in pairing mode. You’ll must take the battery case off and re-install the battery thrice. When you do that appropriately, you’ll see a blinking blue gentle. This blinking gentle means the meter is in ‘pairing mode’.
