The new 4iiii Precision wattmeter of the 3rd generation is the result of the development and experience of the leader in the field of watt measurement on cranks. It is suitable for bikers who use a Shimano XT set and want to enjoy the benefits of power measurement without limitation. Compared to the previous generation, it brings several improvements - more compact, only 5.5 mm high body, designed for the vast majority of frames on the market, further up to 8x higher CR2032 battery capacity, stronger transmitting antenna for less interference, larger measurement range, etc. This package includes a left hand crank with a wattmeter installed, all ready to go.

    This Canadian brand is primarily known for its powermeters that could be seen on the World Tour. Their offer also includes heart rate sensors and a smart bike hometrainer. Their prices are reasonable. By the way, you are supposed to read their name as "Four Eyes".
