Accurately measuring your power just doesn't get simpler and minimalist than by using the CatEye/4iiii Precision Shimano 105 5800 Power Meter. The compact, 9-gram CatEye/4iiii Precision power meter is bonded to a non-drive Shimano 105 5800 crank arm so it's just a matter of swapping this crank arm for the non-drive crank arm on your existing Shimano crankset. The power meter delivers industry-leading accuracy, highly dependable cadence data, and 3D power meter technology capable of measuring tri-axial strain on your crank arm so you can train harder and smarter. For optimal versatility, the power meter is compatible with ANT+ and Bluetooth Smart head units, smartphones, as well as other 4iiii products. The power meter operates for 100+ hours via a 2032 coin cell battery.

Note: the Shimano 105 5800 non-drive crank arm length is 172.5mm.
