A straight shaft paddle is the most commonly used in kayaking. Apart from being less expensive than crank shafts, they can be used for all paddling disciplines without any great disadvantages. Generally fibreglass is the main straight shaft construction material and is widely utilized, in combination with advanced reinforcement materials such as carbon and aramid fiber, due to its impact resistance when used in thermoset resins. Full carbon shafts are used in the industry, but a composite shaft will always offer more advantages. Straight composite shafts are lighter, offer better flexibility and impact absorption over cranks.
We offer two "Ergonomically" cranked shafts, one is designed for Whitewater, and the other for Sea, Racing and other flat water purposes. These high quality cranks, are curved to offer excellent feel, comfort, and to reduce strain & fatigue. The axis of the whitewater crank remains the same keeping the blades in line with your hands, just like a straight shaft, while the Sea paddle crank axis runs behind the blades. Both these type of shafts are a necessity for those who find discomfort using straight shafts, or paddle for long periods.
Our cranks prevent the inward bend of the wrists allowing a firmer grip, which does not over strain tendons and joints. It has been shown that improved performance is not merely a mechanical property. A crank shaft keeps the wrist straighter thus reduces the strain on the forearm, which in turn improves performance and reduces fatigue. The tension in the tendons that run from the fingers, across the wrist, and connect to muscles in the forearm is also reduced. This reduced tension also helps to avoid any involuntary blade flutter.
Both cranks give more indication of the blade orientation - making it easier to position the paddle properly in forward propulsion, heavy whitewater, or when upside down, etc.. They both allow more control over the inclination of the paddle blade thus making turning strokes easier.
