Campagnolo Athena Braze-On Front Derailleur
Campagnolo's Athena Front Derailleur is compatible with both standard and compact cranksets. Its steel cage moves the chain effortlessly between the chainrings and it features an anti-friction coating for quiet, sublimely smooth shifting.
Braze-on front derailleurs mount to either a built-in frame mount (left) or to a clamp mounted around the seat tube like the one on the right.
Capacity is calculated by subtracting your smallest chainring's tooth count from the largest chainring's tooth count. Example: 46/34/24 chainrings: 46 - 24 = 22-tooth capacity.
