I don't think ramps make dbl or trpl friction shifting faster or slower; I
just think they greatly minimize the chance of a miss shift.

I have an STI triple with a mix of 105 and Ultegra parts on my go-fast
bike, a Paul Taylor custom and it's always shifted superb in the front. I
can only remember dropping the chain once ever, and that was when I shifted

Michael,
Good thoughts.
It's not actually at the limit of the set screw, rather, the set screw is
in far enough that (ironically) it's quite difficult at times to shift into
the big ring. At one point during my after-work ride yesterday, I was not
able to get it to climb into the big ring at all
I don't think the folks you cited think that ramps don't help; rather, that
for doubles, not using indexed shifting, they help very little. If you're
running an STI triple, on the other hand, you essentially cast the chain
into the wind and hope that the wind catches it--which is precisely what
I use that campy FD on all my bikes, except the tandem which has a campy
SR. I find they shift superbly. I would be very reluctant to bend one,
since they don't make them any more..
When you wrote that you were at the limit of the set screw I wondered about
the chain line and if the BB was to
So far, so good, but note that sufficient tolerance on the stand may not be
enough when standing and torquing the frame.

Forgot to add that, me, I've never had a problem using old school road fds
on compact triples like the standard XD2 (X2D?) 46/36/24.

I'll add to Eddie's remark that, on those sad occasions when you simply
cannot get the outer limit screw in such nice adjustment to produce firm
shifting without chain drop, it sometimes helps to adjust the angle of the
fd around the seat tube. This is an entirely empirical and "by guess and by

FWIW, I have a 9 speed Campy Racing T, and it works fine with a 46-36-22
triple.

I have a stock RBW Shimano Deore XT front derailer on my Sam. Don't know if
it would help to put that on your bike. I have XD2 cranks. I use Silver bar
ends.
The setup works well.
I have over shifted a couple times, and a couple times the chain jammed on
the way into the big ring, b
I suggest that you start over with your FD limit adjustment. Remove the
cable from the FD. Move the chain to the small chainring and largest cog.
Adjust the low set screw so that the inside plate of the FD just clears
the chain. Move the chain to the large chainring and smallest cog. Adjust
Look at an old nouvo record front derailleur, thats the angled lip that you
want.
All I use anymore are Ultegra changers, but they have the bend built it.

I've always set up my FD's with the outer cage perfectly parallel with the
large ring. And the distance between the bottom of the FD cage and the cog
teeth is a 2-3mm I guesstimate.
The only time I have had trouble with the chain going off the large ring is
from maladjustment . Some cranks
When I went to the rivy chainrings on my Hilsen, I could do NOTHING to get
the microshift FD to keep from slipping off the large ring; I ended up
switching to a XT and it's been hunky dory since.

Bend it. You won't be trashing a perfectly good derailleur, you will be
making a non-functional piece of equipment work.It will take less than
10 seconds. Just grab some needlenose pliers and bend both front edges
in, just a tad.

Interesting. I was thinking a spacer to move the cassette in or out, not
re-spacing the chain rings. But if you have a good line, that's not a
solution.
There's an interesting discussion here on shifting issues with low bottom
bracket bikes.

Most of the standard causes have been mentioned, so I'll just add this: Try
shifting slower/gentler. I used to have a lot of overshift problems with
Sugino cranks - it happens more with them than other models I've used for
some reason - when I was jamming front shifts with abandon. The problem
If the front d is overshifting as to push the chain off the outside of the
big ring, then the outside limit screw...is set in such a way that it is
allowing this to happen. There should be a perfectish setting where the
chain makes it on to the big but is limited by the limit screw making it

Could the large ring be slightly out of lateral true? I've had that cause
derailleur issues before... in fact I had several instances of lateral
run-out until I started greasing the BB spindles before installing cranks.
Haven't had the issue since.

The chainline is dead centered on the middle ring - I had the LBS check
that and they performed the check while I was present. The 113 BB is the
one that is recommended by Sugino for the crankset. If I added a spacer
between the middle and big ring, it seems like it would lead to chain
suck. But
What's the chain line look like? Maybe you need a spacer (or remove a
spacer) for the cog-set and also, a different length spindle/BB cartridge.
I mention adjusting chain line, since you have already worked on derailer
limits and it may be the chain wheels are slightly out of position for the
