With a Deore (newer universal clamp) I can fit:
WTB Motoraptor

With an "older/no shims" 9spd XTR I can fit
Exiwolf
Fast Trak
Motoraptor (duh)
Ignitor

Currently running the Ignitor.

All of these are with the monkey nuts installed and not having switched the cable anchor bolt out.

Might need to look on ebay for one of those ... does it have a part number
designation?????

I got it used from a guy on the New England Mountain Bike Association forums for $10 I think. It works great. I'm not sure of the model number, but if you'd like I can take a close-up photo of it for you.

Oh yeah and I run it without the Monkey Nuts, and with Exis and there is no rubbing on the front deraileur.

Surly blog says LX M571 or XTR M953 ... 28.6 clamp or 31.8 with shim. Now to find
one ...

Other FD options

I'm running a Shimano 105 triple FD with a Motoraptor - no monkeynuts. Full output climbing can cause a little tread rub during the peak power spikes. Just enough to barely hear.

I recently read of folks using "braze on" road derailers with a clamp on adapter -

It says "SIS yes" so it will work with XT/XTR shifters??????? I had looked at this
and that point was not clear (and will work with small chainrings since it handles up
to 56 teeth.)

I think so.
Front derailleur cable pull is the same on road and off road.

You can see riders in the world cup (sauser) using dura ace front derailleur. There are a number of guys in the "save some weight" forum too.

I don't know if rims are another variable to track.

My data points:

Maxxis Ignitors w/ Delgado 29er Disc Rims, SRAM Xgen front derailluer, Monkey Nuts: Will clear but just barely.
(However I had the FD not quite tight enough and the FD turned just a bit so it barely rubbed on the middle chainring till I reset the FD.

Kanda Kahns on unknown 700C road rims, SRAM Xgen FD, Monkeys Nuts: Will clear.

Looking more closely, some say SIS and some say DUAL SIS. They are not
expensive, and looking at the another thread, the FD4403 and FD4400 say
on the shimino site DUAL SIS yes (but speedgoat says the FD4400 won't
work with mountain shifters.) The FD7803 just says "Front SIS".

But for $30 bucks for the FD4403/FD4400 worth a try. Only worry other than
general stuff (will it have the reach to cover the smaller rings when optimized
for the bigger road rings) is that chain line on the KM is at 50, and these are
for 43 and 45 mm. But in theory, with the spacers on the shimano bottom
bracket, one could tweak the chainline easy enough on the hollow tech external
bb.

Local guy at the LBS rides a KM, I can go harrass him one afternoon. ;)

The bigger chainline isn't really a problem. The limiting screws allows to go far enought to climb the big ring.

As for shifter compatibility, we may ask Nino in the save some weight forum.
But i have seen classical MTB shifters with dura ace derailleurs.

Rom1red setup (on the site) works wery nice according to him, and is cheap too.
I will do something similar for the winter (not enough money for a Rohlolf !)

Specialized Fast Trak Pro 29x2.0 clears both the front derailleur and
v-brake cable cross over by 4 to 4.5 mm (measured with an allen wrench.)
(I could clean up my cable run, and the noodle on the V brake would
come up a couple mm at least when idle, the cable housing is bit long.)

Oddly a local shop has a slightly used old style XT derailleur they are trying
to sell fo $40.00. I might try to talk them down ... just to have it on hand.
Just to have 3 front derailleurs ... maybe just another bike ;)
