Top End OSR Racing Chair

Designed for speed, the Top End Eliminator OSR offers exceptional stability and aerodynamics.

The Eliminator OSR features a relaxed headtube angle for great cornering and maximum traction. Combined with the stiff aerodynamic T-frame design, precision track compensator system, integral wrap around fenders, choice of 4 cage styles, aluminum side panels and rubber coated pushrims make this chair fast. It is the pick of Boston Marathon champion Ernst Van Dyk and past champion Franz Nietlispach as well as top wheelchair athletes including Krige Schabort, Kurt Fearnley, Aaron Gordian, Edith Hunkeler, Chantal Petitclerc, Diane Roy, plus Adam Bleakney and his illustrious U of IL Wheelchair Road Racing and Track Team.

If you have your sights set on winning, the Eliminator OSR will help you get to the finish line first!

Measuring Guidelines:

Standard Seat Design Chair: Is recommended for customers who sit in traditional position and/or eventually want to kneel. Recommended for athletes with limited balance or for T-10 SCI level and above. These athletes need more of a bucket or squeeze and this frame offers this and new users.

Cage Style: Cage styles can be seen on pages SV1 and SI1. V Cage is for the advanced racer with good flexibility to transfer and assume the kneeling position. This cage style is stiffer and more aerodynamic. Open V offers an easier transfer than the V Cage and is better for racers with longer or thicker/big legs. I cage is the easiest for transfers but is less stiff than V or Open V cage styles. Often ordered with optional fixed footrests.

Upper Inside Frame Width: This measurement on the chair is the point directly above the axle on the inside of the frame. This usually rides below the lats on the chair user. With the new integral fender, frame gradually gets wider as the fender follows the wheel. This allows room for the stroke follow through. Measure 2" above waist, then measure straight across chest. Typically upper frame is a maximum 1" – 2" narrower than lower seat width.

Lower Inside Seat Width: Inside panel measurement at rear seat rail. The side panels are riveted on the side of frame as standard. Snug is preferred. Use two flat objects (such as books) to press flesh in at the hips and measure straight across.

Axle Position: Typically between 5" – 8". The lower the level of SCI, the more forward the axle position. Minimum for kneeling position is 6". Most of the top racers have between 6 1/2" – 8". Taller people may need the axle more forward (8") and amputees back a bit (5" – 6"). A straight camber tube (new in 1995) increases the stiffness of the chair and includes rear wheel alignment adjustability. The angled camber tube continues to be an option for those needing more room for their feet.

Camber: Most users prefer 11°. Athletes who sit high and/or race on the track sometimes prefer more.

Seat Height: Measured from floor to the top of the seat rail. Standard is 17" rear and 18" front. The 1" difference gives a slight bucket for stability. Trunk length should also be considered: a long trunk may sit lower and short trunked people, higher. The kneeling position requires a minimum of 17" rear and 18" front to allow room for legs and feet.

Rear Seat Height: Measured from floor. Low level SCI athletes tend to sit higher, whereas quads and high level SCI athletes sit lower. Trunk length should also be considered: a long trunk may sit lower and short trunked people higher. The standard rear seat height is 17".

Overall Length: Measured from end to end (rear to front wheel) – between 64" and 76". The average male adult measures between 72" – 76". This measurement for everyone is dependent on the ability to reach the steering system and brake comfortably with tucked into the racing position. A longer chair is smoother gliding and runs straighter, but if it's too long, the ability to "hop" the chair by body force will diminish.

Rear Wheel Size: 700C – most adult men and women. The larger wheel equals more top end speed and is a must for the serious racer. The Top End Eliminator wheel covering fender helps shorter armed people use a 700C wheel as the wheel is covered and protects against chaffing.

Front Wheel: 20" is standard.

Rear Axle: Standard on Top End racers is 1/2" as this makes a stiffer wheel.

Aero Bars: Are standard on the OSR. Steering mounted on the top of the frame for easier reach and improved aerodynamics with removable bar ends.

Rubber Coated Pushrims: Average is 14 1/2" for men, 14" for women. This depends on arm length and power. Range is 13" – 16". Most good racers have tried many sizes over time.

Standard Accessories: Caliper hand brake is mounted on the left steering handle. 3 positioning straps are included (25", 30", 35"). The tool kit includes a pouch that attaches to the back of the upholstery. 5 Allen tools for assembly/adjusting of rear wheels, pushrims, headset, front wheel and side guards are included.
