Campagnolo's Veloce Front Derailleur features an aluminum body and chrome-plated cage for low weight, durability and smooth shifting. And, it's compatible with both standard and compact cranks.
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.
