AFAIK. In any case, the Sportcrafters OP unit needs about 400 watts to achieve 30 mph, while the Elite tech data shows 420 watts at 40 kph or 25 mph, probably on its max setting. For sure not free spinning but should be fine on the lowest setting for easy workouts. My guess. Does that seem reasonable to you, 400 at 30?
I was not referencing the Sportcrafters Overdrive drum but their standard, non-resistance "Cadence" drum.
Sportcrafter claims the Cadence roller is a little over 200 watts at 30 MPH. The data sheet for the OP's Elite rollers claim almost 350 watts for the same speed at the lowest setting. That's 75% more resistance.
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.
