Bobsleigh (bobsledding) is a winter sport in which sleds, normally manned by two-man or four-man crews, are guided down a specially prepared track of solid ice with banked bends. The bobsled is a precision-built machine of aluminium and steel. It has two axles, with two rounded runners mounted on each. The rear axle is fixed and the front one turns for steering which is achieved with either a steering wheel or ropes. The brake is a bar made of hardened steel with a serrated edge located between the two rear runners. In competitions the brake can only be used in an emergency as it damages the ice.
