Shimano's Tiagra Front Derailleur provides quick shifting. The clear-coated aluminum body and plated-steel cage are extra durable so you can enjoy smooth shifts mile after mile.
Your seat-tube diameter determines the needed derailleur clamp size.
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.
