The Shimano 105 12-speed front derailleur is designed to deliver precise and responsive front shifting, with a focus on rigidity and efficiency for modern road drivetrains. Its wide link construction enhances overall stiffness, resulting in improved shifting performance, particularly when under load.

The inclusion of a wide inner link further increases rigidity, helping to maintain smooth and reliable shifts even during demanding efforts. The derailleur utilises a toggle link design, providing light shifting action with shorter lever movement and reduced effort required at the end of the shift stroke. This ensures a more efficient and comfortable shifting experience.

Engineered specifically for 12-speed drivetrains, it is optimised to work with Shimano chainsets that feature wider gear pitch spacing, while still maintaining high shifting performance on bikes with 135 / 142 mm over locknut dimensions (O.L.D.). A support bolt adds extra stability to the system, improving overall performance consistency.

Built with durability in mind, the aluminium components are coated to resist corrosion while maintaining a clean, high-quality appearance over time.
