Accurate and precise data are vital for effective training and the 4iiii Precision 2.0 3D Shimano 105 5800 Power Meter will allow you to train smarter and harder. The unit itself has a compact and lightweight design which adds a mere 9g and is installed into a black or silver Shimano 105 5800 crank arm.
