The Polar S725x cycling heart rate monitor combines the highest level of personal performance data, training conditions like altitude and temperature, and cycling functions. It includes the WearLink coded transmitter, which is made from a soft fabric material that contours to your body's every curve. Featuring a sleek carbon fiber look, it offers a variety of cycling performance measurements, including trip, distance based on interval, speed (current, average, max). It comes with a wireless sensor that measures cycling speed and distance via a magnet rotating on the front or the rear wheel depending on the sensor. It also offers the ability to enter two different wheel sizes, enabling you to train on two different bikes.

This powerful cycling computer enables you record personal performance, running and cycling data plus training conditions like altitude or temperature, then analyze your performance when you download via Infrared technology directly to your PC using the included Polar Precision Performance (PPP) 4.0 software. You can also manage your exercises with a Nokia 5140i or 5140 cellular phone with the MobileLink feature. You'll get instant feedback on your training sessions by reviewing graphical summaries of your exercise on the large color display of the phone. You can also free memory of your Polar product during longer trips by storing the exercise data in the phone.

Train and rest in the right balance. The OwnOptimizer test tells you whether you have recovered enough for your next training session. Based on the test, you are provided with a nice-scale description of your personal training status.

The OwnCal feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. It also allows you to set daily and weekly exercise goals in terms of calorie expenditure. The OwnIndex feature will determine your fitness level, track your improvements, and provide motivation. Polar's OwnCode technology blocks unwanted signals from other heart rate monitors, ensuring disturbance-free transmission of your heart rate data.
