This trainer is a solid performing trainer that is easy on the pocketbook. With a simple and elegant design, the Wind Trainer's fan uses air to create a smooth, even resistance. The vortex blade design is high-powered, but produces very little noise. You'll be pleasantly surprised with this entry-level trainer's extra-wide range of progressive resistance and remarkable frame stability. The die cast zinc fan blades also double as a heavy flywheel for fluid stops and starts and a more road-like feel. The trainer includes a training DVD to help keep you motivated during your indoor exercise.
