This Schwinn 305p stair stepper is in great condition; I have actually been the only owner/user.
It was originally bought from the local Smith's Cycling and Fitness establishment in La Crosse.
Features consist of an on-board computer, padded hand grips, hydraulic cylinders with adjustable resistance, oversized pedal platforms, and transport wheels. The upright design makes it simple to store and use in smaller spaces.
The reference handbook for this design can be found at:.
