A roller-type chain for a bicycle is configured with asymmetrical chain link plates, the chain link plates applicable for use with a chain with reduced chain width as in use on chain drives with a high number of gear ratios. The chain link plates are configured at the inner side of the chain loop for engagement on the teeth of the rear sprocket and of the front chain wheel. The chain link plates are further configured at the outer side of the chain loop for interaction with the chain-guiding roller on the rear gearshift mechanism.

Chain link for bicycles

A drive arrangement for a bicycle may be provided with various interactive components configured to reliably and repeatably engage and disengage with one another both when new and after a period of wear. The drive arrangement may include a drive sprocket assembly connected to a driven sprocket assembly with a chain movable by a gear changer.

Drive arrangement for a bicycle

A power meter for a bicycle includes a body having a torque input section and a torque output section, the body configured to transmit power between the torque input section and the torque output section. The power meter also includes a printed circuit board ('PCB') having a substrate and at least one strain measurement device which may be attached to the PCB. The power meter may be integrally constructed with a chainring construction.

Bicycle chainring

A chainring structure may include a torque output section comprising a plurality of sprockets having two axially bounding sprockets defining an inner-most and outer-most sprocket and a torque input section configured to attach to a crank assembly. The chainring structure may also include a power meter chamber disposed radially between the torque input section and the torque output section, the power meter chamber including a base surface of a strain measurement section. The power meter may be disposed in the power meter chamber and have at least one strain measurement device attached to the base surface. The torque output section, torque input section, and power meter chamber may be formed as a unitary single piece and configured to dispose the base surface axially between the axially bounding sprockets of the plurality of sprockets.
