Polar CS600X Cycling Heart Rate Monitor with Power Sensor W.I.N.D.

The WIND power sensor works better (more reliable)and is easier to install than the older power sensor used with the 720I. Accuracy is good and you have much more memory as well. The software that comes with the CS600 is very informative and easy to use. As for the CS600 itself, it is fine but no better than the 720I except for more memory. If you need a cycling monitor this unit is great. If you already have one of the older polar units such as the 720 and are happy with it then don''t bother.

The upside for the polar CS600x is it''s affordability. You have to ask yourself what are your other options? You can spend a grand for the Cycleop''s Powertap or 2 grand for the SRM. Once installed it is an excellent tool for monitoring your output. For the average income triathlete once it is installed correctly you will appreciate it. I use it on my training bike but could NOT bear to place on my race bike (see below).

Downsides: Installation is time consuming but it is manageable -check out the youtube video -chain removal is probably inevitable and probably the best way to approach it. While on the ride I can''t escape the feeling the power monitoring unit on the chain stay, speed sensor or batter will get knocked off. Lastly, if you, like me, extended your budget and spent a lot of money on a race bike mostly for promise of increase speed from improved weight and aerodynamics -the Polar set up seems antithetical to all these principles.

I''ve used the Powertap my Race bike.
