From Campagnolo's constant pursuit of excellence comes ULTRA, the new carbon chainring designed to transform every pedal stroke into pure performance. The heart of its innovation is the carbon fiber structure, which guarantees absolute stiffness, lightness, and consistent power transmission. The result is a continuous, fluid, and effective thrust that accompanies the cyclist with every pedal stroke. This carbon structure is paired with 7075 aluminum teeth, an alloy of aerospace origin chosen for its extraordinary lightness and resistance to the most demanding loads. Thanks to the thick hard anodizing treatment, the ULTRA gear maintains high performance over time, ensuring reliability and durability for both the chainring and the chain. Every phase of the production process is defined with absolute precision: the composite stabilization occurs at controlled temperatures and pressures, sealing the perfect orientation of the carbon fibers. A procedure that demonstrates Campagnolo's know-how in processing the most advanced materials. Designed and manufactured entirely at the Vicenza plant, ULTRA is much more than a concentration of technology. It is a union of style and performance: the logo and details obtained directly from the mold tell the story of the attention to detail and elegance that have always distinguished Campagnolo products. The ULTRA version is offered in two configurations, 50 and 52 teeth. With ULTRA, every pedal stroke becomes a unique experience, where design, stiffness, and lightness come together to redefine on-bike performance standards.
