Polar CS400 and CS600
Polar on Wednesday released two sports trackers that it says give everyday cyclists a chance to train like athletes: both the CS400 and the CS600 with Power track altitude, distance, and lap times as well as body conditions such as calorie consumption and heart rate. The CS600 will also track the bike itself, Polar says: a 2.4GHz wireless link gauges the energy put into pedaling as well as efficiency and the balance between left and right pedals. Despite the finer nature of the monitoring, however, the extra data works with most bikes and doesn't require changes to individual parts.
Either device works with Polar's custom training software that follows the progress of long-term exercise and lets riders program individual workouts that the tracking devices can recognize, including ones that set goals by the body's output or a set distance. The CS400 and CS600 should be available in cycling and general sports shops immediately for $340 and $600 respectively; a regular version of the CS600 is also available for $420.
