Will you be using your stock air intake system for the bicycle power test, or will you go all modified and use a Breathe-right nasal strip?

Question:
Can't you do a reasonable FTP test on a cycle trainer with a well defined power curve? The local tri club uses KK Road Machines and tests with the defined 40 minute warm up (burn out), then the 20 minute test, convert speed over the 20 min to wattage, then 85% for 20 min FTP (it may be 80%, can't remember). LC, are you saying this is a meaningless or inaccurate test?

Cool, thanks. I don't trust the wattage numbers on my Tacx Vortex, figured the KK curves were a more reasonable read.

Some bikes shops have Powertaps for rent by the day or week. Call around.

Are they, though? An electric system should be able to accurately measure the power being put into the system via voltage measurement, shouldn't it? I would think the reason this method isn't more widely used is that weather and electronics like this don't mix. It seems less complicated than strain gauges and the like, and more stable.

You are welcome to try for yourself. I have used many of them and none of them are close to realistic. They do give you that warm and fuzzy feeling though thinking that you are going to be able to go out and destroy the pro's when you finally decide to do your first race. It is kind of crushing when you get out in the real world and get dropped in the first three miles of a cat 5 though.

....Funny, but mean.
You think a typical gym stationary bike would even get in the ballpark with wattage numbers? It's a pretty simple measurement to make (unlike mileage/speed) based on RPMs and resistance.

This is what I do. I don't know anyone with a powertap. I test myself periodically at the gym and do my HR/Power ratio as a measure of my fitness during a 5 minute all out. I have a gym membership so it is pretty easy for me to do this every couple of months.
