Your titanium bike frame seems to have upgraded your competitive cycling attitude. The next step is increasing your training efficiency with the Polar CS400 Cycling Heart Rate Monitor. The CS400 measures incline and decline steepness in percentages and grades so you can realize that that seemingly Everest-sized hill at the end of your ride is actually just as big as the ones toward the beginning. Set limits on your heart rate so you know when youre pushing your limits and when youve recovered enough for the next interval. The CS400 measures current, average, and max speed, and you can prepare a detailed training program with the included Polar ProTrainer 5 software (for Windows). *Included bike mount, multifunctional handle bar / stem installation.
