CyclingCeramic Pro Aero 2025 Shimano 105 R7100 & 7150 Di2 Oversized Derailleur Hanger

The Pro Aero 2025 oversized derailleur hanger from CyclingCeramic is designed to optimise the performance of Shimano 105 R7100 & 7150 Di2 drivetrains. It combines precision-machined aluminium pulleys, a carbon rear plate and an aluminium front plate to offer an ideal balance between lightness, stiffness and durability.

Thanks to its high-performance ceramic bearings, this oversized system reduces friction and the chain’s articulation angle, ensuring smoother gear changes, better power transfer and increased efficiency, particularly on climbs or during accelerations.

Independent tests conducted by Friction Facts measured extremely low friction (approximately 0.033 W), placing these bearings among the best-performing on the market. Hand-assembled in France and tested in real-world conditions, including in competitions such as the Tour de France, this derailleur hanger represents a reliable and durable upgrade for demanding cyclists.
