it's more a status factor issue. they both work well, I have even resorted to using a Sora on my good road bike because that it what I had at the time. From a mechanical point of view....there is no difference.

The first question is, why do you want to upgrade? If you didn't know the name-label on your front derailler, would you want to upgrade it? I didn't think so.

There is very little to no difference in function of Shimano front deraillers - main diff is weight, and even it's not that much. If you really care, you could go to Thailand (or Washington, D.C.) and buy a Sora derailler that has a Dura-Ace label on it. And some fake Oakley sunglasses to boot.

The Tiagra is pretty much a 105 with fewer cosmetics and should work very well. Shimano front road derailleurs are largly interchangable (assuming you choose double or triple correctly) except for bragging rights.

If it ain't broke, don't fix it. Even for replacement parts, if it came with Tiagra a 105 is best value for your cash. If properly adjusted, they should all shift equally well. Only diference is a few grams of weight between the models.

Unless it's broken, waste of money. The difference in shift quality between Tiagra and Ultegra is noticeable to some, but really not that significant.

Even if it is broken, 105 is probably the best bang for the buck.

Really? For a front derailler?

I had to bikes one with a 105 der and one with a tiagra, I made one into a single ring cross bike so I took the 105 off that and replaced it with my tiagra, I saved 20 grams ahah and didnt notice too much in shifting.

I upgraded my Tiagra rear mech with sealed cartridge bearing pully wheels. It makes a small difference to the shifting but saves on maintenance.

I believe that there might be some (slight) differences with the rear derailler, but I doubt there are with the front.

If you believe what some say around these forums, then yes, some people say they can feel a difference in the shift quality.

Differences in the rear derailleur are definitely noticeable, but not enough to justify an upgrade if the current one ain't broke.
