Both the CS100 and the similar CS100b are handlebar-mounted Polar wireless cycling monitors. The only difference between the two is that one (cs100) is equipped with the Polar T31 coded transmitter for heart rate monitoring and the other (CS100b) is not.
The CS100 is a complete system which includes three new features to Polar's already amazing arsenal of information: the Polar Cycling Coach (a Web-based coaching program and diary), estimated time of arrival (based on your speed), and automatic display scroll, which switches the information on the display according to your preferences
If you prefer to keep things simple you can chose the CS100b. It comes without a heart rate transmitter, so it’s ideal if you already have another Polar product or if you simply want a cycling computer without heart rate monitoring.
