When this number came onto the market it marked a massive innovation in the field of low-profile wheels. What is innovative about the Racing Zero Carbon wheel is the concept: carbon and aluminium blend together to form a unique combination that has successfully re-interpreted the Racing Zero legend with a top-of-the-range version. It has frequently been praised as super stiff thanks to the aluminium spokes, super reactive thanks to its lightweight rim as well as boasting razor-sharp precision during riding, in addition to being Sturdy and comfortable, light and stable during the tensest moments of a race. What else is there to add? Nothing, except that this wheel for racing bicycles can be improved with a new, lighter, more reactive and stiffer rim. The aim of Fulcrum's R&D department was clear and perhaps seen as a given: the character is not to be touched but the performance can be improved. The rim's standard measurements have stayed the same: 30 mm in height with a 17C groove that is a perfect fit for the 25 mm clincher tyres. What has changed are the materials and the internal and external structure. Twill carbon has been used plus AC3™ technology for improved braking.
