Abstract
Abstract A one-track sliding vehicle or sled having a supporting frame, a steering mechanism rotatably mounted at the supporting frame and a front steering runner and a rear runner connected at said supporting frame. The front steering runner is supported at the steering mechanism or at the supporting frame itself by a spring or shock-absorber leg which is adjustably mounted, thereby allowing the steering runner to be optimally adjusted to the particular driving conditions such as, for example, deep snow
