Our ALDHU® spider features a cleverly designed spline interface when mounted to the axle that delivers a robust yet smooth engagement allowing you to maximise the efficiency in transmission of power in your pedal rotation. Combined with our new ALDHU® cranks and Q RINGS oval chainrings or Round chainrings, the innovative spider includes refined OCP Mount technology so you can now adjust your optimal chainring position by precise one degree increments. Engage your unique OCP to unleash a more efficient pedal stroke, reducing knee stress and possible injury. The enhanced 12.5 percent ovality heightens your performance advantages providing full activation of muscle groups, creating more power and diminishing long term knee strain.
