On a related question, what is the difference between the flat-bar FD-R453 and road bike FD-4503?
The FD-R453 is compatible only with Shimano flat bar shifters, whether marketed as "flat bar road" or "mountain" the cable pull is the same, and is incompatible with normal road front derailleurs.
For your Tiagra STI shifters, you'll need to use the FD-4503, which is a normal road front derailleur, designed to be used with road shifters. Any other Shimano road triple front derailleur would work as well (Sora, 105, etc.)
