SportCrafters recently developed patented ARC Power Modulation Technology, which provides the foundation for most of our product line. High power magnets inside of the roller drum are drawn closer to the drum wall as speed increases, and, in turn, resistance increases. Benefits of this new technology include:
Cyclists experience the same resistance that they would find on a fluid stationary bike trainer, but without the tire wear that comes with clamping to the rear wheel.
Tests have concluded that the power profile with speed comes as close as possible to real-road conditions.
As an added benefit, the resistance unit adds less than a pound to the standard roller drum. Also, there is absolutely no maintenance required and no risk of fluid leakage.
You can purchase a progressive resistance drum, also known as an OverDrive Drum, to upgrade your existing SportCrafters or CycleOps brand bike rollers. Contact us if you aren't sure the drum will work with your rollers, we are happy to help!
“... We are loving the rollers, especially with this year’s extended Colorado winter…The resistance is also making it much easier for the athletes to do high power workouts inside without having to get on the trainer. Resistance feel wise, I can’t tell the difference between your rollers and high quality fluid trainer.”
