Bicycle frames are hollow thanks to the genius of design, the intelligence of science and the power of engineering. The iconic ‘double diamond’ frame shape hasn’t really changed in over 125 years. However, the components and materials used to manufacture frames have altered over time. A key principle, however, is that a frame should retain as much of its original shape under load (frame stiffness) when you turn the pedals, corner, or brake. Different materials of frame design achieve this to differing degrees. Other design principles are the frame’s ability to withstand crashes, and the frame’s resistance to repeated strain over time (frame fatigue). Designers, of course, also consider how the frame materials affect the comfort of your ride.  What…
