Shimano Dura-Ace FD-7800 Front Derailleur

Dura-Ace FD-7800

Radical improvement in front shifting is one of the most significant advances in the new Dura-Ace. The 7800 Dura-Ace front derailleur still offers the legendary performance you''d expect from Shimano drivetrain components, but has been tweaked to accomodate the new 10 speed drivetrain.

Strength:

Functions like it should

Weakness:

Poor QC

FD 7800 The outside steel chrome is chipping and corroding after two years of non-rain use. My Campi Super Record is corrosion free after 30 years of use.
This will need to be replaced well before it's useful lifespan.

Strength:

Works great.

Weakness:

Shoddy finish, chrome flaking off and corrosion underneath

I bought a new bike with full D/A group approximately one year ago and probably have about 6,000 miles on it. The D/A front derailleur continues to work flawlessly; however, when I was cleaning my bike the other day I noticed that the chrome coating on the derailleur was flaking off in a couple of places and pitted in others. Where the chrome had flaked off, the metal was corroded underneath. I was surprised as I haven't ridden this bike much in the rain, and although I live in a hot humid area, keep the bike inside my air conditioned house when not riding it. I am going to seem if Shimano will replace under warranty and will try to remember to post an update.

Strength:

Shifting is quick.

Weakness:

Doesn't work well with FSA compact crank. You have to let up the pressure on the crankarms to get a decent shift.

I can only evaluate this derailleur's performance with a compact crankset. My bike came with an FSA compact crank 50-34 and a Dura Ace 10 spd setup. The Dura Ace front derailleur seems to have some problems adapting to the compact design. Firstly, the upshift is very temperamental - you have to let up on the crank before shifting to ensure a smooth shift. Otherwise there is grinding and protests from the drivetrain. Also, I keep throwing my chain if I am in #7 or 8 in the rear and go from the big to small chainring in the front. I can't seem to get the adjustment right.

Similar Products Used: Campagnolo Veloce and Centaur - shifts much more smoothly than the Dura Ace.
