The new 105 front derailleur leverages the wide inner link design introduced at the Dura-Ace lever to assertively move the chain. Combined with the improved chain guide shape, silky smooth and seamless shifts can be made even under the heaviest of loads.

Again, I test rode Ultegra and Dura Ace, and the front derailleur action of any of these all feel the same, and if you notice the way a front derailleur works you would come to same and logical conclusion. So what do you get for more money to get Ultegra or Dura Ace, just a wee bit lighter component. And since the front derailleur is not used anywhere near as much as the rear it will last a very long time. I got mine in silver to match the bike and it looks great. 105 is the sweet spot for the Shimano line, low cost, reasonable weight, and high durability.
Solid derailleur and a good price, unfortunately the cage is too narrow for my 9-speed drivetrain and requires constant feathering as I shift the rear.
this has been a great derailleur. i know why you would pay more, but if you are watching you pennies instead of your grams, then 105 is the way to go. top performance at a good price. and i like the black color scheme.
