Please select options Unavailable


The Dura-Ace Front Derailleur is Shimano's top-of-the-line front gear changer. The body is made of forged aluminum for top-notch strength and the pivots are extra wide for amazing shifting. Plus, the lightweight, replaceable aluminum cage is nickel plated for durability.

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.
Braze-on front derailleurs mount to either a braze-on frame mount (left) or to a clamp mounted around your seat tube (right).
