This has been well used on my carbon road bike, that sadly cracked beyond repair.. Selling the Di2 components to help pay for a new bike! The Shimano Ultegra FD-6770 Di2 Front Derailleur is a high-quality aluminium component designed for road bikes with a 2x10 speed setup. This braze-on front derailleur by Shimano, made in Japan, includes a 2-year manufacturer warranty and is lightweight at 100-199g. The sleek grey colour and bottom pull cable design make it a stylish and functional choice for cyclists looking for precision and reliability in their bike components.
