Shimano Tiagra Braze-On Front Derailleur (Triple Chainring)
Shimano's Tiagra Braze-On Front Derailleur provides quick shifting. And, the clear-coated aluminum body and plated-steel cage are extra durable so you can enjoy smooth shifts mile after mile.
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: 53/39 chainrings: 53 - 39 = 14-tooth capacity.
Shimano Tiagra Front Derailleurs are compatible with 9-speed drivetrains.
