These wheels roll with exceptional efficiency and as they are the stiffest and lightest Racing Quattro to date, they provide a noticeable advantage in any cycling situation. The superb weight and stiffness is a significant benefit when climbing aggressively, racing your way up the steepest climbs. When it comes to the descents, their flex-free construction and Fulcrum AC3 braking track enables you to keep the speed up with confidence. When corners approach you have the power, consistency and safety to brake competitively and maintain your speed when it matters most.
These wheels shine during Road Races and Endurance events where Fulcrums attention to detail and performance comes to life.
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.
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.
Featuring no holes on the central section of the rim means that the rim is uniform at every point, free from critical areas subject to stress. The advantages are immediately clear: less weight, longer lasting rims, greater resistance to fatigue, the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.
