Shimano Y2BA12000 road front derailleur internal protection plate
(5 reviews)
Compatible with Ultegra, 105 and GRX
The Shimano Y2BA12000 protective plate clips onto the inner part of the front derailleurs on the Ultegra, 105 and GRX ranges. Its main function is to guide the chain smoothly and quietly when shifting from the small to the large chainring. It is important to keep it in good condition to avoid operational issues and/or the inability to change chainrings.
