V2 ATRA Speed Reducer web Transformed fine grained snow -10CThe 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 are easy to engage, whether for increasing resistance or for slowing the skis down when negotiating moderate downhills.
