Plain Old Carbon Fibre Isn’t Enough


Technology just keeps moving forward and benefitting the world of cycling.

Only a few days ago, SpyCycle featured new tyres made by Italian company Vittoria containing Graphene, which achieved a remarkable reduction in rolling resistance.

Today we learn of the use of a new form of carbon fibre that uses “Spread Tows” instead of yarns in the material’s construction. Branded as TeXtreme ® by Oxeon AB, these Spread Tow reinforcementsare a new choice in making ultra light composites as the technology is flexible and tow-size independent which enables development of optimized reinforcement solutions tailor-made for specific application needs. Utilization of TeXtreme® Spread Tow carbon fabrics and carbon UD tapes by manufacturers of advanced aerospace, industrial and sports products confirms that 20-30% lighter composite parts can be produced with improved mechanical properties and superior surface smoothness.

This next generation of carbon fibre has been used by Spanish bike manufacturer Berria, who showed off their 2016 bikes at the Unibike show in Madrid last week. They were supported by Oxeon and the TeXtreme product with Finite Element Analysis or “FEA” (a computerised method of predicting how a product reacts to real-world forces, vibration, heat and other physical effects to show if a product as designed with break, wear out, or work the way it was designed).

David Vitoria, R & D Manager of Berria Bike explained: “We are very pleased to have TeXtreme® carbon fiber fabrics in our top range of frames. In order to learn more and to really make sure our frames were designed and utilizing the carbon fiber materials in an optimized way we partnered up with TeXtreme® to take it to the next level. Their expertise in Spread Tow reinforcements, composite design, the product quality of the fabric; all were important aspects for us and they delivered oneverything.

The use of TeXtreme has meant that Berria were able to build bike frames that have ultra light weight combined with previously unthinkable high stiffness values. This has improved the reactivity and the feature set of their bikes.

You can tell how advanced this technology is when you learn that other users include Formula 1, Americas Cup yachts, NASCAR, Le Mans and some advanced aerospace applications.

Berria is not one of the best known brands in the UK, but has a name steeped in history and, they say, a passions for the world of cycling, with a lot of experience in Switzerland and with Swiss technology, as well as in their home market of Spain, with their factory based in the centre of the country.
