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.
Racing Zero Carbon is an improved version of the Racing Zero wheel, and is the most sophisticated and innovative racing wheel, made for experienced gran fondo riders, for passionate cyclists who clock up the kilometres to improve their speed, looking for time on the climbs, that perfect feeling, the satisfaction that comes from challenging yourself. For those in search of the ultimate legendary experience.
The Racing Zero Carbon is suited to any race event. Perfectly at home on tough climbs, high-speed descents, Gran Fondo events and endurance challenges. These wheels will boost your road riding experience and increase your performance from the first pedal stroke.
AC3 - All Conditions Carbon Control
AC3 enables surprising braking performance, which is very noticeable in difficult weather conditions. Rather than using the traditional machined brake track approach, Fulcrum uses micro laser incisions on the brake track surface to remove resins and create a smooth surface. Lab tests have shown that this process improves braking power by an improvement of 6%. However, in the wet, this performance increase jumps to 43%. Bringing braking in the wet closer to the performance experienced when riding in dry conditions.
USB (Ceramic Ultra Smooth Bearings)
Using high-end ceramic balls, which perform continually thanks to the absence of lubricating grease and the precise machining of the cup and cone technology, the friction is reduced drastically and in turn, increases the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings.
Advanced Carbon Rim
This technology was developed by Fulcrum and is the combination of different types of carbon fibre, including unidirectional and the famous 90° 3K found on wheel models at the top of the Fulcrum range. Fulcrum developed a special HTC (high transition grade) resin, which has a glass transition point at a higher temperature than any other carbon fibre used within the bicycle industry. This provides exceptional stiffness, durability and braking performance.
