Cateye / 4iiii Precision Power Meter Ultegra 6800

by - verified purchaser
This is my first PM. Always heard that training with power meter will make a huge difference in the way you measure you performance. I have to say that this powerful instrument will give you with high degree of confidence and consistency the data you need to train effectively. I have had for 4 weeks now and every day I can see how my performance is progressively improving. Power is the best measure of fitness in cycling. The higher your power is the stronger you will be.
