Bicycle frames
Modern bicycle frames consist of two triangles fused together.
This style, known as the diamond frame, is the main component of most
standard bicycles and to which the wheels and other components are then
fitted. Frames are generally measured from the center of the bottom
bracket to the top of the seat tube. This measurement is vital to a
rider’s comfort and safety while riding.
Bicycle frames come in a variety of materials, some of which increase
the expense of production considerably. Steel, aluminum and titanium
frames are standard on the market and are used in many cases to make
specific types of bikes, such as those used exclusively on the road
for competitive cycling, or those used on the trail for BMX or adventure
sporting.
When shopping for bicycle frames, it is important that a consumer understands
their ideal frame measurement, the most common type of cycling they
plan on doing, and whether they desire a gender specific or neutral
frame. Becoming familiar with the various materials used to construct
a potential frame is also key, as this will greatly affect the longevity
of the bicycle and its overall weight.
