SHIMANO FD-5700 105 Double Front Derailleur (31.8/28.6, Black)
- Improved chain guide shape delivers smooth shifting at each rear position, even under heavy load.
- Stiffer, wide inner link design with two pivots increases strength, rigidity and eliminates the need to manually trim the outer chainring - no more chain rub in the big-big combination!.
- DUAL SIS front indexed shifting with optimized spring tension reduces the shifting effort required to move between chainrings - the result is featherlight downshifts and smoother upshifts.
- Forged aluminum construction lowers weight without sacrificing durability.
- Use with Shimano Dual Control Levers for both small and big ring trim.
