Most cyclists are obsessed with speed. Cycling speed is affected by a number of factors, including aerodynamics, power, and weight. When it comes to weight, carbon fibre is amongst the lightest of materials from which to build a bike. It’s also easier to form obscure shapes from carbon fibre for the purposes of improved aerodynamics (versus, say, aluminium). Furthermore, carbon bikes are arguably smoother to ride, thanks to the material’s slightly shock-absorbing properties. For these reasons, carbon fibre bikes have become highly desirable.
An entry-level carbon bike starts at £1,000 ($1,350 USD). A pro carbon bike can cost as much as £30,000 ($40,000 USD).
