Overview
Looking for speed and adjustability? Well now you can have both with the new Top End Force RX. By combining the speed design of the Force X with the adjustable design of the Force R, Top End created the ultimate lightweight, aerodynamic package. The frame is fabricated from 7005 heat-treated aluminum and is designed to allow for a more reclined position.
What Makes This Different
Top End gave this handcycle a more streamlined look by adding sleek new dropouts and re-routing the cables through the head, tube keeping them hidden and out of your way. Includes upholstery cushions, drafting bumper, chain guard, and a safety flag at no extra charge. Besides the great included standard features, there are many upgradable options to choose from, ensuring you get the perfect fit and performance.
Why We Like It
The Force RX gives you two back options: carbon fiber or welded. The standard carbon fiber back is super lightweight and adjustable without sacrificing strength and stability. The 7000 aluminum welded back upgrade option is also lightweight and strong, but is custom made for the ultimate fit.
What You Need To Know When Ordering
The Top End Force RX is custom built for you and is therefore, non-returnable. To ensure the handcycle is built to meet your specific needs, please print out the order form on this page and read over the measurements required to create the best fit for your handcycle. If you require CAD measurements, you'll need a tape measure and protractor to determine some angles. Then place your order for your Top End Force X online and call Spinlife at 1-800-850-0335 to provide your measurements. The final CAD drawing will be emailed to you.
- 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.
