A shock device for an at least partially muscle-powered two-wheeled vehicle, including at least one tube system having two telescopic tubes, the tube system extending from a first end to a second end. A suspension system is provided which is effective between the two ends and which biases the two tubes to an extended position. The suspension system includes a positive air spring and an independent, series-connected supplementary spring. Both the positive air spring and the supplementary spring bias the tube system to the extended position. The supplementary spring shows a lower breakaway force than does the positive air spring, and the ratio of the suspension travel of the positive air spring to the suspension travel of the supplementary spring is higher than 4:1.
