Multiple sprocket assembly for a bicycle
Abstract:
A multiple sprocket assembly engageable with a roller chain and mountable to a driver of a rear wheel of a bicycle. The multiple sprocket assembly includes a smaller sprocket and a larger sprocket. Each of the smaller and larger sprockets has a radially outer ring with a plurality of teeth for engaging the roller chain. The radially outer ring has a plurality of radially outer pin mounts including a hole. The radially outer pin mounts are aligned with the teeth. The sprockets have a plurality of radially inner pin mounts connected to the radially outer ring forming a single piece. The radially inner pin mounts includes a hole. The radially inner pin mounts are aligned with the plurality of outer pin mounts disposed on an adjacent smaller sprocket. A plurality of pins connects the smaller sprocket and the larger sprocket to each other. The pins are mounted in the holes in the outer pin mounts on the smaller sprocket and in the holes in the inner pin mounts of the larger sprocket. A first mounting sprocket is connected to the smaller sprocket by pins and a second mounting sprocket is connected to the larger sprocket by pins. The first and second mounting sprockets are supported on the hub axle at two positions spaced, apart in the axial direction of the hub axle.
