Reviews over the

4iiii 105 7000 Precision 3

Affordable power sensor with more than satisfactory accuracy. Quick, easy calibration. Easy to dismantle and assemble if you want to move from one bike to another. Thanks to the printable template on the site, I was sure that the crank would be compatible with my Orbea Orca Aero. Impeccable delivery and service as usual.

The powermeter is easy to mount, for me the hardest part was taking off the pedal as it was tight. Connects quickly to the app + any other apps you use. Battery was already at 92% though

Pros & Cons

After easy assembly and connection, it is immediately ready for use. Because the power meter is unidirectional, it is recommended to average out the power to take out the fluctuations. A fantastic upgrade!

Pros & Cons

Very easy to install and calibrate. After 2 outings, the data seems very consistent.

Pros & Cons

I was looking for a power sensor that was affordable and above all compatible with my aero bike, which has very little frame clearance at the crank passage. I've followed the various reviews of this new version of the 4iiii sensor and I have absolutely no regrets. I had no trouble fitting the 105 version of the 4iiii sensor to my ultegra crankset, and the weight of the cranks was exactly the same on my precision scale (207 grams). Only the 4iiii application for updating the sensor firmware gave me connection problems, but these were easily solved with another, much more practical application. Beware also of the state of the original battery, mine was 70% good when I received the sensor. A good idea if you want to take it easy.
