The ATRA (Advanced Training Resistance Aluminum) Speed Reducer has a machined aluminum bearing retainer for the best heat dissipation and strength. The lever actuated system has one neutral and four resistance positions that is easy to engage whether for increasing resistance or for slowing the skis down when negotiating moderate downhill’s. For steep terrain we recommend the use of a brake.
Suggested Retail $54/pair. (one speed reducer required per ski)
