Alex from Silicon Valley Cycling Center continues our series of intros to power meters by giving a brief introduction, the Polar CS600 with Power and heart rate.

The CS600 measure power by using the Power Output Sensor W.I.N.D. direct from the chain, unlike other models that use the crank or hub. This precision system combines measures from two key factors: chain tension, (using a sensor on the chain stay) and chain speed (using a sensor on the rear pulley.) The polar is not only the lightest power meter in the series on your wallet, but it's also the lightest system on your bike, at a measly 275 grams for the whole system installed. The system retails for $710.
