I have a bike with a 4503 Shimano setup (Tiagra triple, 9 speed). The front derailleur is broken.
I can quickly get a 105 derailleur (5703) at the local bike shop. I just want to be sure that it is compatible with my shifters, and be sure I can get a clean shifting experience.
Differences between the old and new front derailleur:
- Tiagra vs 105
- 9 speed vs 10 speed
Can anyone confirm the FD-5703 will work on my bike?
