Bike frame
The modern bike frame consists 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.
Bike 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 a bike frame, it is important that a consumer understands
their ideal frame measurement, the most common type of cycling they
plan to do, 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 effect the longevity of the
bicycle and its overall weight.
