Building your own bike starts with the carbon frame. Carbon is high-tensile steel, reliable, strong, and long lasting. It's not light, but it gives your bike just enough heft to be steady across all types of trails. Need less weight? Opt for carbon fibre.

The more you pay as you build, the lighter your bike will be. Geometry decides on how efficient you could attack a road: Aggressive bikes are at 72-73 degrees on the head tube.
