Highlights
Why we rate it
Automatic trim
The cage follows the rear mech, so it never rubs and needs no manual trim.
Synchro Shift
Pairs with RD-RX815 for full or semi-synchronised shifting.
Clears wide tyres
The gravel chainline leaves more room than a road Di2 front mech.
Keeps 11-speed Di2 going
A genuine replacement for existing GRX Di2 2x11 builds.
