| Power Training This is the place to talk about training and racing with power (watts) measuring devices such as Polar 710/720, Power Tap, SRM or any other power measuring device. |

I have the Performance Bike (made by Elite) Real Axiom VR Trainer. I find the speedometer on the trainer reads about 1 mph slower than both my Polar 725x and VDO cyclometers. I'm wondering if anyone has done any comparisons with regard to the accuracy, or lack thereof, of the electronic ergometer/trainer power meters versus the on-the-bike power meters. |

I voted for the Powertap SL (which I've ordered this morning and hopefully will arrive next week) basically because I'm fed up with the very average performance of my current (soon to be 'ex') Polar system and the prospect of the new Polar units being a cosmetic 're-hash' of their current unit, albeit 'wireless'

Am somewhat surprised by the poor relative showing of the Polar versus the Ergomo considering the much higher price and accuracy issues of the Ergomo versus the Polar, and the impression I have of the number of people who say they have a Polar, maybe the people who do have a Polar buy a lot of them, leading the popularity to be low as measured by this poll? OTOH I have three PowerTaps so if we had a different sort of survey... On other - some people may consider the HAC (among others) a power meter... |

I have a VDO cyclometer hooked up to my rear wheel in addition to my power meter/stationary trainer (RealAxiom VR Trainer by Elite) and it appears the power meter/trainer reads, on average, 1 mph slower than the VDO computer. This translates to an ~30 watt lower displayed power reading!! |
