GRX 2x12 mechanical front mech
Shimano GRX FD-RX820 Front Derailleur
A light mechanical 2x12 GRX front mech with a toggle-link design and a built-in cable tensioner. Its gravel chainline clears wide tyres, and it suits 46-48T outer rings.
Highlights
Why we rate it
Lighter lever feel
Toggle-link construction cuts the effort needed for front shifts.
Easy setup
An integrated cable tensioner makes fine adjustment quick, with no inline barrel needed.
Tyre clearance
The chainline sits 2.5mm further out than a road mech to leave room for wide gravel tyres.
Wide range
A 17T capacity covers GRX 48-31T and 46-30T chainsets.
