    Overview of the Top End Force K

    The Invacare Top End Force K offers outstanding performance in a kneeling position handcycle. It is available in three custom, made-to-measure aerodynamic designs. The Force K Kneeler is used by the most able athletes, while the Force K Para Kneeler is for paraplegics who prefer the kneeling position to that of reclined and the Force K Double Amp. Kneeler defines the kneeling position for amputees.

    Like other Top Force handcycles the Force K features a center frame construction with an internal rib which reinforces the frame making it super stiff for maximum transfer of power. Controlling through turns is smooth and fast with the Top End dampener system. The 27 speeds operated by the Rapid fire hands-on shifter/ brake delivers smooth, responsive shifting and braking right at your fingertips plus the easy-to-operate, no cable, virtually maintenance-free manual upper derailleur system take the guess work out of the chain rings.

    • The Top End Force K Handcycle is a kneeling position handcycle available in two custom, made-to-measure aerodynamic designs.

    • The Top End Force K Double Amputee Kneeler is custom designed for the double above-the-knee amputee.

    • Requires dialed-in, precise measurements – for the athletes who train to win!

    Measuring Guide

    Seat Depth1
    Measure from the most posterior point of the body to the inside of the knee, minus at least two inches. Optimal contact between the legs and the seat increases stability for the body.
    Back Height2
    Measured from the seat base to the top of the chair back. Sport users need enough height for upper body support, yet low enough to allow the arms and trunk to rotate freely.
    Rear Seat to Floor3
    Measurement from the ground to the rear seat edge. Relative to the front seat-to-floor dimension, this determines the rearward slope ("dump" or "squeeze") of the seat. Sport chairs usually have more dump for extra upper body stability.
    Hanger Angle4
    Determines how far the toes extend away from the body, measured from the horizontal. Sport users often use very tight angles to be able to rotate in the smallest possible space.
    Seat Width5
    Determined by the widest point of the body from knee to hip, plus an inch to ensure room to move. Sport chairs are typically as narrow as possible to save weight which improves agility.
    Wheel Camber6
    Angle of the wheel relative to the vertical. More camber improves stability and agility, but also limits ability to pass through narrow spaces. A typical sport chair uses nine to twelve degrees of camber.
    Front Seat to Floor7
    Measure the leg from the back of the knee to the sole of the foot. Then subtract the thickness of the cushion when it is compressed. Next, add a minimum of two inches for footrest clearance. Do not add the footrest clearance if the chair will be foot-propelled.
    Footrest Width8
    Measure from the inside of each legrest tubing the distance or desired distance between legrests.
    Center of Gravity9
    Measure from the front of the seat back post to the center of the rear axel.
    Seat to Footrest Length10
    Measure from the edge of the seat upholstery to the top rear of the footrest.
    Backrest Angle11
    Measure the the angle of the back post to the floor. Ninety degrees will be perpendicular to the floor, to approximate the angle from the back post to the seat, subtract two degrees from measurment for every .5" of dump.
