Doug,

I use a Suntour alpha-5000.  Works great, although the Shimano Sora
mentioned in another post should be easier to find.

I've got the same setup on my Atlantis except I went with the Sora
derailler.  Works great - just the right clearance and never throws
the chain.

It's kind of hard to see in these pictures, but I have my All-Rounder
(26" wheels) set up with an older (but not too old) Campy Chorus FD.
I got it for a song a few years ago on closeout at Nashbar.  (Last
year's model?  How hopelessly outdated!)



I have 46-42-26 chainrings and don't have any shifting issues.


Hope this data point helps.

Cheers- Mike in So. Boston, Mass

2008-12-17 Thread Eric Norris

When I set up my Road Standard with a Campagnolo compact (50/32  
double), I ended up using a standard (Chorus, I think) derailleur.

The "triple" compatible derailleur I had used in the past with compact  
rings didn't want to work correctly.  The standard "double" derailleur  
works flawlessly.

The best FD I've ever used on a "Riv style" compact triple is the
Campagnolo Racing T.  Shimano makes a MTB front derailleur intended for
48T big ring, and it works fine - I have several of them - but they just
don't shift as nicely as the Racing T, and they stick out behind the
seat tube a lot, enough to interfere with the fender on my Velo Orange
(not likely to be a problem on an Atlantis, though).

Both of these are made for compact cranksets and have fairly short tails
on the derailleur cage.
