The new XL Speed Reducers are designed to accomodate both the 125 and 150 wheels. The bearings are now mounted in such a manner that they can easily be moved for either the 125 or 150. The new lever is designed so pressure is applied to both serrated roller arms for improved pressure distribution. For the Aero 150 the system has one neutral position and 4 resistance settings and the 125 has 3 resistance positions. The ATR functions equally well in both dry and wet conditions.
The ATR assembly is made from aluminum, stainless steel and nylon. The lever is easy to grab and pivots on solid stainless steel pins. Nylon rollers and washers are used to reduce noise generated by vibration from skiing on rough surfaces. Almost all Aero skis are sold with the speed reducer system.
One speed reducer is needed for each roller ski. Sold Individually.
