CyclingCeramic’s Race 2025 oversized derailleur hanger is designed to optimise the performance of Shimano Ultegra and Dura-Ace drivetrains. Thanks to its large-diameter pulleys and high-performance ceramic bearings, it reduces chain friction and improves pedalling smoothness for a noticeable gain in efficiency on the road and in competition.

Its machined monocoque structure, combining aluminium and carbon, offers an excellent balance between stiffness, lightness and alignment precision. The optimised chain path ensures constant tension, promoting sharper, smoother and quieter gear changes, even when pulling hard on the chainring.

Hand-assembled in France and individually tested, this derailleur hanger benefits from a design proven in race conditions, notably in prestigious events such as the Tour de France. It is aimed at demanding cyclists seeking maximum performance, reliability and mechanical efficiency.
