Shimano GRX Di2 FD-RX815 11 Speed Front Derailleur
The Shimano GRX RX815 Di2 2x11 Speed Front Derailleur allows you to shift smoothly and quickly on the new GRX cranks, with a larger difference between the inner and outer leaf. It also allows you to tilt your chain and allows for wider tyres. All this is achieved with a redesigned cage. Newly designed cage The cage in this groupset is longer and wider. This allows you to maintain a fast and smooth gear change up to a 17-tooth difference between the inner and outer ring. It also allows you to shift your chain 2.5mm, making it easier to find the right gear. In addition, this front derailleur, by changing its position, also allows you to fit wider tyres in your bicycle. Need for a clamp? Some bikes do not have a brazed-on mount for the front derailleur. If that's the case on your bike, you need a loose clamp in order to mount this front derailleur.
