Introducing PowerCal a new kind of Power Meter

[BicyclePower]

Thanks. I understand what you are saying, but Eldron has also a strong argument in that it is about your no's and consistency over a period of time. So the PowerCal should also show a % increase compared to the PowerTap in your power figures

 

correct!!

Question is how does it calculate watts based on heart rate? If you take a relatively fit person compared to an unfit person. Both could be pushing the same heart rate but with completely different power outputs.

 

Don't get me wrong. I am merely asking the question.

I'm waiting for a answer to this as well.This is great.I can lie on the couch pop some caffeine or run some adrenaline or any or thing that can effect my HR and still have some good power numbers without even getting off the couch.

Not trying to be a smartass here but just genuinely trying to understand how this works:

 

It sounds like it is a heart rate monitor strap with a processor that runs an algorithm from which it derives data that is then broadcast on ant+ - is this correct?

 

Would it also be correct that this algorithm could be run on any data set provided by the output of any heart rate monitor when it is being worn. i.e. if one had the algorithm then one could run it on the raw data provided by a standard heart rate monitor so in essence it is the algorithm wherein the value lies and as such would not be published for external verification?

 

the unit was not just developed by CycleOps but together with the University of Colorado Boulder so surely these has been plelty of verification of the algorithm.

 

your assumption is correct that the PowerCal is just a HR strap with a fancy processor that runs the algorithm

Here is Something from "DC Rainmaker" see Link http://www.dcrainmaker.com/2011/06/first-look-at-new-cycleops-joule-and.html

me thinks this is a load of donkey dick.... save the money and buy a proper CycleOps power meter

R10 000.00 is a bit steep for me.This is a wonderful option.

I agree, it does depend how serious you are about the figures. Fair enough

 

Another interesting estimated power calculation method is the way Strava(www.strava.com) calculates you wattage from your speed and elevation gain. One of the downsides here is that the terrain does not come into the calculation.

 

Will be interesting if you can use HR and gps data..

Ja, you gets what you pays for.

Dave put my name on the waiting list,Now be patient and try to wait for my "PoweCal",well I wanted to buy a power meter for 6years($$$$$$$ is the problem) but this will do just fine

 

Same here. Put me on the list please, as I will take is as of yesterday, was it already available.

i assume whats great about this tool that even if you have a powertap you need to change wheels etc, here you can roll on your mtb, training bike and race bike and you can get a more consitent spread of data.. currently i do only 1 out of 5 sessions on my powermeter as mostly on mtb, and too lazy to swop wheels every 3rd day.

 

yes, it may be fully accurate, but as long as the deviation is consitent then you are getting the value of a plotted line going up or down, and thats all you care about. data is all about frequency of data spread as the more dots on a scatter plot the easier it is to draw averages etc.

1. It will be interesting to compare power from this with a real PM and with Strava's calculated power.

2. It looks to me like it will be more inaccurate for mountain biking, where a lot of variations in power/gradient/whats under the wheels happen.

 

I wonder what it will show if I run with it

Couldn't sleep last night,want to play with my new toy.Can't wait to see if I got a 1000Watts in my legs(Dream)

your name has been added thanks. we will keep everyone updated on these units in the mean time i welcome everyones thoughts some good some bad but with all new products there is scepticism.

yes it is possible to run with, we have the first test unit on its way to SA as we speak should be here next week, as soon as it arrives i will put it though its paces and try give some states as to what it is like against a PT
