Ultra-light and highly durable
In addition to cyclists’ strength and stamina, performances like these are made possible by lightweight racing bikes. Regulations state they may not weigh less than 6.8 kilograms, equivalent to seven liter of water. Fulfilling these requirements often necessitates components such as brake levers or gearshift parts made of ultra-light yet highly durable materials.
One material that fits the bill is Tepex®. The high-performance composite, made by LANXESS, is based on thermoplastic polymers reinforced with glass or carbon fibers. This accounts for its remarkable strength and stiffness, and makes it extremely lightweight. Especially the latter is decisive for Tour de France cyclists when battling uphill in the Alps and Pyrenees as it allows them to exert less effort to turn the wheel.
