Bicycle frame

A bicycle frame is the main component of a <a href="/facts/Bicycle/nxBVrlBF">bicycle</a>, onto which <a href="/facts/Bicycle_wheel/0Lf9C53L">wheels</a> and <a href="/facts/List_of_bicycle_parts/CxMbFsyn">other components</a> are fitted. The modern and most common frame design for an <a href="/facts/Upright_bicycle/YeEkPKo4">upright bicycle</a> is based on the <a href="/facts/Safety_bicycle/YeEkPKo4">safety bicycle</a>, and consists of two <a href="/facts/Triangle/cRXUwsMn">triangles</a>: a main triangle and a paired rear triangle. This is known as the diamond frame. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes.
A frameset consists of the frame and <a href="/facts/Bicycle_fork/VYK82hcp">fork</a> of a bicycle and sometimes includes the <a href="/facts/Headset_(bicycle_part)/4Ugp6ENR">headset</a> and <a href="/facts/Seat_post/3tgx7TlD">seat post</a>. Frame builders will often produce the frame and fork together as a paired set.
