[1] Bicycle seats come in three main styles: mesh, hardshell and combination.Hardshell seats are normally made of a composite material such as GRP or carbon fibre although metal and wood versions do exist.A hardshell seat is normally covered with some-form of padding, this is usually closed or open cell foam although some extreme racing machines do not have any padding on the seat to reduce weight and increase efficiency.Some riders complain of excessive road noise vibrating through the hardshell seat.Also, the hardshell seat is "closed", providing no ventilation, which may cause excessive sweat to build up on the cyclist's back on hot days.
