Shimano GRX 400 FD-RX400 Braze-On 10-Speed Front Derailleur FDRX400F

Shimano GRX 400 FD-RX400 Braze-On 10-Speed Front Derailleur The Shimano GRX 400 FD-RX400 Braze-On 10-Speed Front Derailleur has been designed specifically for gravel riding, using its modified design to deliver crisp and accurate gear shifts across double chainring configurations. The sturdy format has a wider chainline than standard road front derailleurs, and this affords more clearance for broader gravel tyres, ensuring that no contact-based mechanical mishaps can occur when out in the wilderness. This front derailleur is compatible with braze-on style frame attachments and works optimally with a 10-speed Shimano HG chain and GRX 10-speed chainrings. It can handle up to a 46T sized outer chainring and has a capacity of 16 teeth, allowing a wide-ranging gear setup to be used for heavily mixed riding topography.
