Help! PowerTap or SRM Trainer ? I need advice pleaseCARBON110

Hey guys,

I want to buy a bike computer that i can read my strength in watts, heart rate, cadence,etc. The power tap is about a $1000 with software and a rear wheel to put it on. But the rear wheel is VERY heavy and I could not use it in a race that has any hills. The SRM has years of pro use and is $1400 for the amature and $2000 for the pro. The amature weighs a little more and is + or - 5% accurate. The pro is lighter and is + or - 2%. I like these since I can race with them and they are proven performers. I don't know how accurate the Power Tap is. But it only gauges the rear wheel as opposed to the cranks in SRM. Anyway, do you think a Amature SRM is as good as a Powertap? Is it worth spending 2K for the Pro? Help me out all suggestions welcome. By the way I really have been enjoying the Forum recently!

Wiht respect to your accuracy realted concerns, I would not worry too much about that. I think consistancy in reading is more important. I have heard that Power Tap is a solid consistant read. The SRM is not comparable in terms of quality. If you can afford it get the SRM. My two cents!

I'd get the power tap. What kinda info would expect to gain from using a power meter in a race? it would only be helpful in training and a TT. unless you are controlling the pace the entire time of a crit, you are following the pack. who cares how many watts you are pushing. Those 2 things are meant as training aids. during a race you should just be concerned about making the breaks and doing as LITTLE work as possible.
again, if you are considering a SRM, i'd go with the Pro model since its shimano spline compatible. AFAIK, the amatuer is not, only square taper. AS far as weight, the hub weight is basically inconsequential (PT hub is only 200g heavier than DA and only 150g heavier than Ult), and do you honestly think that the SRM cranks dont add any weight?

3 training partners of mine use the PT. it works well and is consistent. However your 1st week on it will be useless becuase you will be constantly looking down at your wattage and not really paying attention to your riding. After that its all good though.

Thanks guys! I am buying a Power Tap since its what my new coach uses and its $1200 less than the Pro SRM. I'LL let you know how it works out. I appreciate your info and opinions
