4iiii Precision Pro 105 R7000

The 4iiii Precision Pro 105 R7000 power meter is a double-sided powermeter for cranks of the Shimano R7000 series. It measures the power on the left and the right crank arm and on the spider on the right side. The 4iiii power meter is now in its 3rd generation.

The widely used CR2032 battery lasts for a whopping 800 hours of operation. The measurement accuracy is ± 1%.

The special feature of Shimano: the 4iiii 105 R7000 Precision Pro Powermeter fits not only to cranks of the R7000 series, but to all Hollowtech II road cranks (eg Dura-Ace R9100 or 105 R7000).

Since Shimano is most commonly found on road bikes, the 4iiii 105 R7000 Precision Pro power meter is also great for watt based training at training camps - given the rental bike is equipped with a Hollowtech II road crank.

The 4iiii 105 R7000 Precision Pro power meter is available in the common crank lengths of 170-175mm and with the chain rings 50/34, 52/36 and 53/36. 

Thanks to ANT+ and Bluetooth Smart, the 4iiii power meter is compatible with all ANT+ capable bike computers and smartphones with Bluetooth Smart technology.
