Rollers are an excellent way for cyclists to stay in gear through the long winter. But many roller systems tend to be fairly passive and only offer a little actual resistance. But SportCrafters looks to make riders work a little harder with the new patent-pending power bicycle roller system, which utilizes magnets in the roller drum. All produced is quickly dissipated as well, so there is no worry about the drums getting hot. Additionally, as this is magnetic based there is no friction, no fluid and no fans.
As such there is also less noise than traditional resistance trainers and nothing to wear out, with no calibration or adjustment. And no maintenance. The entire device also offers less weight as well. And should less resistance be desired the user can reverse the drum. This progressive resistance roller drum can be installed on any SportsCrafters, CycleOps Bi-Fold and even older Nashbar bi-fold rollers. Let the good times… roller!
