Star Trac 3900
The Impact Absorption System of the TR3900 uses the same patented soft deck as Star Trac's top of the line TR4500. A dual-cavity rubber cushion runs along the entire deck surface to spread and absorb impact. In combination with a custom extruded aluminum uniframe, this unique system provides a 50 percent softer running surface for improved comfort and stability plus quieter operation. Incline Range 0 percent to 15 percent, in 0.5 percent increments. Speed Range 0.5 mph to 10 mph (0.8 to 16 km-h) in 0.1 mph increments.
