The SportCrafters ZRO110 OverDrive Pro Rollers are a high-performance bike roller set built around our core values of quality, robust design and innovation.
Rollers have been regarded as a superior training tool for many years because of their ability to hone riding technique. For the first time ever, the OverDrive Pro Rollers combine the benefits of roller training with the powerful resistance of a fluid trainer. Resistance automatically increases with speed in a non-linear fashion (for a graphic depiction of the power curve and an in-depth review, check out this Testimonial). For the most comprehensive training experience, pair your roller training with a TrainerRoad subscription and Sufferfest videos.
