Dura-Ace brifters with 48-34 chainrings

[Eric Douglas]

I'm setting up my new road bike with the intention of making the gearing as versatile as possible.
I'm considering trying to use a Dura-Ace brifter with 48- and 34 tooth chainrings. I realize that
this setup is not ideal, but I have run 46-36-24 chainrings with the same front deraileur (however,
the shifter was non-indexed). Are there any potential problems? Any suggestions?

I'd suggest you use Ergo shifters. A regular Campy front derailleur will shift the 48/34 ok. For
perfection, you grind a little of the nose of the front derailleur down to get it to conform closer
to the shape of the 48.

I use a 48/34 for most of my events, which are usually long distance. In town, I use a 12/23
cassette and when it gets really mountainous, I put on a Shimano 12/27 or a made up Campy 9 12/28.

may work with a normal dbl front der or perhaps a ultegra triple fder...

Don't you run into compatabity problems using a Campy brifter with a Shimano cogset?

Not up front. ;-)

I'm using Ultegra 9s STI levers with 48-34 TA chainrings on a 110BCD Deore XT crank and a Suntour
XC4050 front derailleur. All seems to work fine...
