A three-column infographic titled ‘The materials science of cycling’, with an image of a red bike in the centre.

The first column looks at the materials used in bike frames. These include steel alloys, aluminium alloys, titanium alloys and carbon fiber. 

The second column looks at bike tire materials. Tire treads and inner tubes are made from rubber with additives; the structure of an example synthetic rubber is shown. The casing of bike tires is made from nylon, while the tire beads are made from steel wire or Kevlar.

The third column looks at materials used in biking accessories. Cycle helmets have an inner impact-absorbing material made from polystyrene foam, with a polycarbonate outer shell. Cycle jerseys are often made from polyesters, sometimes with elastane added.
