Special Eccentric Hand-Bike Chainring

This chainring was made eccentric specifically for the hand-bike world. This feature allows the athlete to overcome the bottom dead center by regulating the rotational motion of pedaling. This chainring has a multiplicity of holes in the center for the bolt circle which is designed to accommodate only 5-arm cranks or spiders and which allows the athlete to choose the optimal phasing configuration of the crank position with respect to the assigned zero position.
