Shimano FD-RX825 GRX Di2 Umwerfer

Shimano front derailleur for the named series — the chainring-shifting mechanism. Matched-series pairing with the crank, shifter and chain is essential to shift-feel; band-clamp / braze-on fitment and pull-ratio compatibility are the spec points that determine install fitment to your frame. GRX is Shimano's gravel / adventure groupset — clutch-equipped derailleurs, wider-range gearing, ergonomics tuned for on / off-road riding and hood-level grip on rough surfaces. This is the Shimano FD-RX825 GRX Di2 Front Derailleur.
