The Invacare® Top End® Force™ RX Handcycle is super easy to measure. It is more customizable than the Invacare® Top End® Force™-3 Handcycle because you can pick from multiple seat widths and frame colors, component options, fork styles, hand pedal and crank arm sizes plus select an aero fork and even your footrest widths. Custom is what we do. To learn more please see the Force Series tutorial, it explains everything. See the order form attached below.
