Need a bit of extra control? The speed reducer can help. The ATRXL98 is designed for use on the XL98R and XL98SL rollerskis. The stainless steel roller arms and machined aluminum lever make it light and strong while nylon rollers and bushings reduce noise. Dual bearings ensure solid contact with the wheels and it works well in both wet and dry conditions. The lever actuated system ensures even pressure distribution and has one neutral and four resistance positions that is easy to engage for increased training resistance or for slowing the skis when negotiating moderate downhill’s. However, for steep terrain we recommend the use of a brake.
