Bike Racing Helmets Details
A cycle helmet should generally be light in weight and provide ample ventilation, because cycling can be an intense aerobic
activity which significantly raises body temperature, and the head in
particular needs to be able to regulate its temperature. The dominant
form of helmet up to the 1970s was the leather "hairnet" style. This
offered acceptable protection from scrapes and cuts, but only minimal
impact protection, and was mainly used by racing cyclists.
More widespread use of helmets began in the U.S. in the 1970s. After
many decades, when bicycles were regarded only as children's toys, many
American adults took up cycling during and after the bike boom of the 1970s. Two of the first modern bicycle helmets were made by MSR, a manufacturer of mountaineering equipment, and Bell Sports, a manufacturer of helmets for auto racing and motorcycles. These helmets were a spin-off from the development of expanded polystyrene foam liners for motorcycling and motorsport helmets, and had hard polycarbonate plastic shells. The bicycle helmet arm of Bell was split off in 1991 as Bell Sports Inc., having completely overtaken the motorcycle and motor sports helmet business.
