CyclingCeramic Aero rear derailleur hanger for Shimano 105 Di2 R7100/50 12-speed & R7000 11-12-speed

The CyclingCeramic Aero rear derailleur hanger is designed to optimise the aerodynamics and efficiency of Shimano 105 Di2 R7100/7150 12-speed and 105 R7000 11-12-speed drivetrains. Developed for road bikes and time trials, it reduces drag whilst improving the mechanical efficiency of the drivetrain thanks to its protection that prevents air from rushing into the pulleys.

Its oversized geometry (14/19 teeth) reduces the chain tension angle and minimises friction, offering a smoother pedalling experience and a measurable performance gain. The aluminium pulleys, featuring low-friction ceramic bearings, ensure optimal power transfer, which is particularly noticeable during sustained efforts and high-speed accelerations.

Machined from aerospace-grade materials with a rigid and lightweight monocoque structure, this hanger guarantees perfect alignment under tension. The optimised chain path maintains constant tension for precise and silent gear changes. Hand-assembled in France and individually tested, it is designed to withstand the high stresses encountered in competition.
