A Measure Of The Power That Drives The BicycleTwo decades ago, Polar popularized the use of heart-rate monitors as training tools for athletes, both professional and amateur. More recently, dedicated cyclists have added another indicator: their actual power output, usually measured in watts. Cyclists generally capture that information with special hubs or cranks that contain tiny strain gauges. Polar is trying an alternative approach. The Polar CS600 With Power, available through bike and sporting goods stores and online retailers, relies on sensors that capture slight differences in chain vibration as well as chain speed to calculate power output. Unlike some gauges, the Polar system does not require replacing any part of the bicycle, but it does add an unsightly battery pack and several sensors. The CS600 appears to have overcome the technical problems that plagued a power measurement system Polar briefly offered several years ago. At $700, the CS600 is exceptionally expensive for a bicycle computer. But that price is well below the cost of strain-gauge-based alternatives, even excluding the cost of installation, potentially making it attractive to amateur racers or even some recreational riders. And, yes, the CS600 still measures heart rate. Tag CloudExternal InformationAdditional InformationChinese Chemicals Flow Unchecked to Market...Living With Pain That Just Won?t Go Away...
