Multiple backrest types
Whether you're an amputee who wants to get your weight up and over the hand cranks or a low-level quad who needs plenty of trunk support, the Shark S can meet your needs. The Shark S features a low profile block-style backrest for riders who involve their entire torso in the propulsion process (shown in picture). For hand-cyclists who need greater trunk stability, an ergonomically designed multi-adjustable contour back is available that adjusts to any angle between 30° and 90°..

Adjustable arm-cranks
The extremely lightweight state-of-the-art Three-way adjustable arm-crank is a technical masterpiece. It can be individually suited to the rider's specific seat-angle position, arm length, and riding technique. If desired, customized cranks can even be made to fit a specified measurement.

Shimano gearing 
The Shark S features Shimano® racing gearing, known world-wide as a premiere racing derailleur and gearing manufacturer. The Shimano Ultegra derailleur system provides highly sensitive and accurate shifting. It offers a finger-flip shifter that riders can activate with one finger. For those who wish to avoid getting caught between gears, Shimano is the ultimate competitive solution.

Stiff frame construction
The one-piece frame profile is designed to meet the stringent standards required at both amateur and professional competitions. Using a "Y" shaped connecting-weld between the fork and frame, along with a special internal reinforcement structure, the Shark is able to deliver superior efficiency and better overall propulsion.
