Description

Description

This 4iiii Precision R7000 power meter is an excellent power meter with a great price-quality ratio. The sensor is placed on the left crank arm of a 105 R7000 crank. Of course, this crank arm fits a 105 R7000 crank but also a 105 5800, Ultegra R8000 or Dura-Ace R9100 crank.

Exact measurement
This power meter provides a very precise measurement with a deviation of only 1%. The power is measured in the left crank arm and is doubled to measure the total power of both legs. For most riders, the difference between the left and right leg is very small, making this power meter an excellent choice for your bike.

Compatible with most bike computers
This 4iiii Precision 105 R7000 power meter transmits a Bluetooth and ANT+ signal. Thus, this it can be connected to almost all modern bike computers such as Garmin, Wahoo, Polar, Mio, Lezyne and Bryton.

Simple mounting and calibration
Mounting this power meter is very easy. After installation it is important to calibrate the power meter via the 4iiii Device Configuration App, which is available for Android and IOS. Through this app you can also check the status of the CR2032 button cell battery. This battery has a lifespan of more than 100 hours. The power meter unit weighs only 9 grams, which is very light indeed!

Compatibility

Caution
The part of the crank on which the power meter is mounted protrudes slightly from the original crank. This can cause problems with some bicycle frames. You can perform a test to determine whether your frame is compatible. To do this, you need to be able to move a AAA battery vertically between your crank arm and the chainstay. There is an image on the last product photo of this page to check this. Optionally, 4iiii website also has a handy document that you can print out and stick on your crank. Then you know exactly between which points the AAA battery must be able to pass. When there is enough space for the battery, you can assume that the 4iiii Powermeter is compatible with your frame!

Absolutely wonderful

- Patrick 31 December 2020

Bought two, one for me, one as a Christmas present. Looks clean, easy to set up, its great for Zwift and looking back at your efforts when on the road. Also great for comparing with my mates. Everyone needs a power meter and this is such good value for money. Also easy of use compared to my old hub based PM is wonderful
