I just picked up a powertap last week and need to do my 20 minute FTP baseline. Talking with one of the guys in my club who also uses power, he advised me to do it on rollers for a consistent measurement. From my point of view an indoor test would seem to be easier than doing it on the road.

Any statistics or data that says a FTP should or should not be done on rollers?

Thanks

Not that I know of. The important idea is to be consistent so you can compare the numbers over time. If you do it on the rollers, you have the advantage of controlling the weather, wind, etc. so that the next time you do it your number is comparable to the one before.

Don't do it on the rollers unless you are doing most of your training on the rollers. Trust me. You can't generate the same power indoors pushing a 20 pound flywheel as you can outdoors.

Suggest you do both indoor and outdoor tests and see how different the power output is for you.

Some people cannot generate the same power indoors, some people can. There are many factors:

I've found that I can't develop as high a 20 minute FTP on rollers as I can outdoors (by quite a bit). Even with a big fan going, the windows open, and a TDF video going on the flat screen. I have no real idea why! The good news is that you will be able to compare your current roller numbers with your future roller numbers to chart your progress. Just don't read much into the comparison with outdoor numbers.
