 Bicycle seats come in three main styles; mesh, hardshell and combination

A typical mesh seat consists of a metal frame with mesh stretched over it and secured with adjustable straps, zip ties, string or shock cord.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.
