Polar 720i (710) Power Meter Performance
I'm currently interested in the Polar Power Meter for the 720/710 HRM. I
have researched the web and have a pretty good idea as to how they compare to the SRM and the Power Tap. I'm looking for individual feed back, not so much on accuracy as consistency. I should metion that I currently have a 720i and I'm not willing to sink another $700 (Power Tap) to $1500 + (SRM) on another system. Most of the sites I found using google dealt with accuracy which the Polar falls behind compared to the others mentioned above. I don't care if I'm 40 watts off actual on a particular climb only that the next time that I ride that climb I'm still 40 watts off the actual wattage. I know that this is very difficult if not impossible to test. What I'm looking for is gut feeling on consistency of this power meter... Thanks, -p |

Polar 720i (710) Power Meter Performance
I have the power meter and am quite satisfied with it. Can't say much about
accuracy against other units, but when comparing my efforts w/ same meter suits me fine. Only issue that I find is that it appears to suffer from interference near power lines. I pass by a network of powerlines when I ride and sometimes see my power go up to 900 watts. I think " pretty impressive... I'm on par w/ Cippolini", but once I get past the line it returns to the 200 watt range. Oh well. Set up was easy on my road bike. On my triathlon bike (KM40), has a curved chain stay and I was unsure if I had the placement set right. Comparing power between the bikes, they appeared similar, so it was probably not an issue.

Your bike is probably draining power from the powerlines... ;-) One one of my routes, there is a point where my heart rate goes up to 280 bpm, the speed up to 80-90 km/h and my cadence to 150-200... It last for 5-10 seconds, then it's normal again. No powerlines around, but I can see an antenna nearby the road. -- Jørn Dahl-Stamnes |
