The Invacare Top End Force RX Handcycle with adjustable carbon fiber back is the latest competitive handcycle in the Invacare Top End Force Series. The Force RX Handcycle combines the hypersonic speed of the Force X Handcycle design with the adjustability of the Force R Handcycle in a lightweight aerodynamic package. The 7005 aluminum heat treated frame is fabricated with slick one piece side frames, plus there are multiple enhancements to allow a more reclined position without interferences. The custom reclined frame with adjustable feather weight carbon fiber back is ultra-light and super stiff. The Force RX Handcycle is a completely customized racing machine which includes a SRAM®X9 30 speed drive train, or you can upgrade to top-of-the-line SRAM XX or Rival Shifters.
