Polar introduces the ultimate performance monitoring system for cyclists. The S720i combines the highest level of personal performance data, training conditions like altitude and temperature, and cycling functions. With the new Infrared technology, you can download directly to your PC without a separate interface. Get back from your workout and in seconds, the most in-depth performance analysis is right there on your PC. New enhanced Polar Performance software lets you look at your workouts every 5, 15, or 60 seconds. The pause feature allows you to walk away from your bike for up to 30 minutes, without losing the current exercise storage file. The S720i features a new lightweight stainless steel design for added durability.
