Welcome to the International
Bobsleigh & Skeleton Federation


The sled is an aerodynamic machine made of fiberglass and steel, mounted on four highly polished steel runners. The two front runners have approximately three inches of lateral movement and are attached to ropes held by the driver, who steers the sled. The brake handles are located on either side of the brakeman in the four-man sled and in front of the brakeman in the two-man sled. The temperature of the steel runners is taken electronically immediately prior to each race. Heating the runners is illegal. At the finish line, the sled and crew are weighed to ensure they are below the maximum weight. All sleds are standardized according to specifications set by the IBSF.
