Let me see if I have the details straight:
1) Rivendell frameset
2) Rivendell-specific crankset
3) Fairly typical Rivendellish cassette
4) Rivendell-supplied rear derailleur
5) Front derailleur taken from a bucketful of identical front derailleurs

Modern triple FDs are designed for a specific combination of chainrings.
For example, the IRD FD in the photo is an exact copy of the Shimano 9
speed Ultegra Triple and 105 Triple FDs. Probably made by the same company
that made it for Shimano. The bottom edges of the derailleur plates are
properly
These kinda questions are ever a can of worms. A "good" FD is one that
functions as called upon, regardless of it's name, shape or size. So, since
you have the Altus on hand, try it.
But first . you say you need to replace your FD, why ? Be specific.

It's a triple with a wide-ish cage to clear 7/8-speed chains, which I
prefer on 9-speed systems cuz you don't have to trim as often to clear the
narrower chain. Assuming you're using friction front shifting it should be
fine*, index compatibility is a whole 'nother kettle of beans or whatever

Hi everyone,
I need to replace my stock Rivendell front derailleur. Can someone please
recommend a good front derailleur?
Here’s my existing setup:
Appaloosa
Rivendell Silver crankset and 3 rings
Rear cassette: Shimano XTR 11-34T
Rear derailleur: Shimano Deore long cage
With the exception
I'm not a mechanic or an expert. But I've set up two compact doubles in the
past year:
- On my Hillborne: A SunXCD 42/24 with a Suntour Cyclone (Mark I)
- On my MB-2: A TA Specialities 42/28 with a Suntour AR
In both instances I had to run the derailer a lot higher than I thought I
should
I agree with Garth and Andy. I've got an old Campy shifting a 50/45/26, a
Suntour AR or Vx (I can't remember which) shifting 42/34/19 on my Atlantis,
and whichever isn't on the Atlantis is on my Trek shifting 45/42/24. I've
also used Cyclones. It often takes a bunch of fiddling and trial and
Shaped inner plates hate wide chainring choices, they're made for corporate
combinations to assure legal counsel of perfect shifting with their
derailleurs, shifters cassette combos and other spec. What I found when
building up my wide double (46/30) rando with RH cranks was that with all

Said mechanic here. There are many better than me but it was my full time
gig for 7 years so I've adjusted my share of FDs, and i don't think there
is any adjusting to get this combination of FD/crank/bb to work well. I've
been out of the game for a few years now so maybe i've just lost my touch
Matt,
I just saw this thread. I had your exact same problem (compact double
crankset w/ 46-30 rings + front derailleur). When shifting from small to
big, it wouldn't or the chain would jump over onto the crankarm. I was
sure I installed the correct front derailleur.
I examined the FD I i
Thanks all. When the FD was lowered, the chain could not climb up to the big ring. First thing he did was lower it. I tried it myself, when I first got the bike. I just ordered a cx70. If that doesn’t work, I’ll get new VBC or figure something out.Also figured out the brake levers were long pull. S
The hiccup here is his double is really more of a triple with the middle
ring removed; lifting a chain from 28t to 46 is a big climb. I'm not sure a
double is going to cover this, but I agree lowering the derailer is a good
idea.

Your FD needs to be lowered a fair bit. At the point of closest approach,
there should be only about 2mm clearance between the top of the chainring
teeth and the outside derailleur cage as it passes over the teeth. I have
doubts about the experience of your "experience" mechanic if he positioned
+1 on Garth's recommendation to use a road double. Something else to
consider is the BB spindle length. Is it longer that needed? I had a nice
SKF BB with a long spindle and had over shift issues as well. I switched
to a BB with a shorter spindle which helped a lot. Also improved the chain

Try a road double instead. It'll shift that easily. FD specs have only do
with what a mfr. makes, not the real world where combo's are endless. Your
clearance of the bottom of the cage depends on the frame. I used to shift a
26/44/48 on my custom road bike with a 105 double(5500) and it was
