Best carbon road bike: what makes good quality carbon and bikes to considerSince carbon can be moulded into more aerodynamic shapes, this is also a factor taken into consideration and tested with more computer and wind tunnel analysis. How are carbon road bikes made? Carbon on its own is too brittle, so it's mixed with epoxy resin which moulds the fibres together and makes it more able to deflect impact. Once the resin is added the material is called Pre-preg carbon. We produce bikes has also experimented with using Graphene mixed into the material to offer better weight to strength ratio.That's not to say that the Ultra-High Modulus carbon should be used everywhere. A good carbon fibre frame uses varying grades Of carbon across the construction - utility stiffness is optimum in some areas (bottom bracket shell, down tube), a little flex elsewhere (seat tubes, chainstays) is an asset. When it comes to constructing a bike frame, there are two popular methods used. Most major brands will layer the sheets of carbon fibre, to varying levels of thickness depending upon the quality required. Decisions as to how the carbon layup should be distributed are usually made by experienced engineers, or with the use computer software. It’s usually then tested in the real world and refined to perfection. The more investment the bike builder or brand can invest, the more sophisticated you can expect computer software used to be. The direction in which the carbon fibres face has an influence, too – unidirectional (all facing one way) fibres offer the best stiffness to weight ratio. But they’re brittle – so woven carbon is much more common – it copes with impact better and is easier to mould, particularly at complex junctions.
