The frame is the heart of any road bike. The most common frame materials include aluminium, steel and carbon fibre. The geometry of a road bike frame can vary according to the intended use, with either ‘race’ and ‘endurance’ frames. Racing bikes will feature steeper angles for speed-focused racing positions while endurance bikes offer a relaxed, upright riding position favoured by newcomers.
Road bike frames can be designed around ‘classic’ or ‘compact’ geometry, and can cater for either rim or disc brakes. “Women-specific’ frames are optimised for the female anatomy.
