Shimano FD-R443 front derailleur : a quick look

Shimano DR-R443 front derailleur for triple front rings
For road bikes with a flatbar
This one is compatible with 7-8 speeds. I think the newer version also fits 9 speed.
For double front rings you would choose the FD-R440

This is the front derailleur on my commuter bike. It seems to be specifically for road bikes with a flatbar. I guess intended to be used for a road-bike chainset with mountain bike shifters. Maybe the indexing is specifically set.

Good quality. I have seen some shops list it as a Tiagra component, but my research does not confirm this. Looks more like a component from no group.
