Product Details

The GRX Di2 RX-825-F 2x12-speed front derailleur was developed by Shimano specifically for maximum tyre clearance. Thanks to the generous chain guidance and the 2.5 mm outwardly offset chain line, it is also possible to ride particularly wide tyres, which are becoming increasingly popular on gravel bikes. Naturally, the electronic GRX front derailleur shifts with the high precision typical of Shimano.
