Polar CS600 Wireless HRM Cycle Computer



A complete training management system in a user-friendly package

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Polar's CS600 HRM is a stunning piece of kit for the serious cyclist who loves a bit of number-crunching to keep their training on track, and it’s really pretty simple to use.

What does it do? Geez, where do you start? Aside from brewing a post-ride cup of tea and giving you a massage, there’s not a lot the CS600X doesn’t do.

You get all your common or garden bike computer functions: speed (current, average, max), distance, duration, stopwatch… all the usual stuff. Then there are a bunch of less expected features like temperature, altitude, gradient, cumulative ascent/descent, calorie consumption… You get the idea. Go to for the full list: it’s massive. You can measure cadence (crank rpm) too, although you have to buy an extra sensor for that.

Plus, as you’d expect from Polar, the CS600X delivers your all heart rate information. You can set the zones you want to hit and have visual and audible alarms alert you if your intensity drifts, and you can even have your heart rate displayed as a graph to show you how it’s progressing.

If you want to get even more technical, you can use this with Polar’s G3 GPS Sensor WIND to track and record your routes on mapping software like Google Earth. Or you can match it with Polar’s Power Output Sensor WIND which measures left/right leg balance as well as a reasonable power reading – although, in our experience, it’s nowhere near as accurate as a PowerTap hub or SRM cranks.

All of this data is saved so you can scroll through it when you get home or, much more convenient, transfer the files via infrared communication to your PC. There you can analyse away on Polar’s ProTrainer 5 software which comes as part of the package (you need Windows 2000/XP/Vista; sadly, it’s not Mac compatible). This acts as a training diary but also puts all the data into easy-to-understand charts and graphs so you can see exactly how your fitness is developing.

It might sound intimidating but this computer is actually very intuitive to use and all the info is easy to understand. You get used to it quickly and will soon wonder how you ever managed without.
