Bike roller specialist SportCrafters has unveiled its new integrated progressive resistance system that provides resistance to the rider from within the roller drum.
According to the company, this gives a ‘non-linear power profile that provides realistic power versus speed. The new patent-pending roller drum uses magnets in a uniquely dynamic application. All heat produced is quickly and effectively dissipated through the large spinning surface of the roller drum so the drum never gets hot.’
The company notes that there is no friction, no fluid, no fans, no noise, nothing to wear out; and the entire device adds less than a pound to the weight of a roller. It’s all inside the roller drum, so it is inherently robust with no add-ons.
No calibration or adjustment are required by the user, and there is no maintenance. The user can also reverse the drum in the roller and turn off the progressive resistance feature, allowing an easier spin at high RPMs.
The progressive resistance roller drum can be installed on any SportCrafters, CycleOps bi-fold, and older Nashbar bi-fold rollers made by SportCrafters. The roller drum resistance system is available now at approved retailers listed on SportCrafters.com.
