Sportcrafter Overdrive (resistance) drum is a completely different animal and this isn't what I was talking about. To answer your question however, Sportcrafter has a video which shows a power meter used on the Overdrive rollers and it is in excess of 400 watts at 30 MPH. I don't use a power meter so that's all I can go by.

Back to the OP's rollers, I was just comparing them to what I have and if the manufacturer's graphs are to be believed then they are not as free spinning as the Sportcrafter Cadence rollers.

Thanks for the reply, Tim. I was a little confused because of course a free-spinning set will have less resistance than a resistance set. I hadn't seen the tech on the Elites at their lowest level. I'm guessing that my resistance set is 400-450 watts at 30, just judging by Strava. Wild guess. However I'm in zone 1 at 13 on my set, which is OK, so I'm guessing the OP should be able to do recovery work on his set as well as ordinary training. Being down to 8 mph in zone 1 wouldn't be fun on rollers however, and I hope that's not the case with the OP. But I suspect the resistance curves for different magnetic resistance units look about the same.
