Centaure Compact Crank Question?

Quoted message said:

I'm thinking of purchasing the Campagnolo Centaure Compact
Crank 50/34t. It's compatible with my Campy 111mm bottom bracket.
Will I have to change my front derailleur to clear the chain?
I'm using a 53/39t with an older Campy Super Record front derailleur.
thanks,

Haven't tried that combo (compact with an old-style Campy front derailleur),
but suspect that it might work. I'd give it a try and see. You're only
talking about a drop of 2 teeth more than the 53/39 you were using, and the
curvature of the cage was made with a 52t in mind for the largest chainring
(53 wasn't very common back then) anyway.

Simple answer: no.

At worst, you'll have to lower the front derailleur a bit, perhaps
6mm. The cage should end up a couple millimeters above the chainring.
There's a neat picture of this, along with a bunch of good tips, on
the Park Tool front derailluer page:

Mike,
I was worried more about the 34t on the crank when using the smaller cogs.
Not sure if the front derailleur cage drops far enough to clear the chain.

We have, and Mike has our usual advice - try it.
Today there's one exactly that spec in our 'daily photo' today:

New frame, chain and crank. Almost always OK with multi-step front
changer and a reasonably not-worn chain.

yellowjersey,
can you post a picture of the same bike with the chain on the smaller
chainring and possibly a 14t cog? Just want to see if the chain clears
the front derailleur cage.
.....or if you can do it, and tell me if it clears.
thanks,
-tom

Tom,
FWIW, I swapped out a Campag Centaur standard issue crank for a the
same in a compact crank. Used the same bottom bracket -- easy. 9-
speed Campag brifters with Shimano 9-speed cogs. All I had to do was
remove one link from the chain and adjust the deraillers. Works
perfect.

Thanks Larry,
I have almost set-up as you.
I'll be using the same Campagnolo 111mm bottom bracket for the Centaure
compact crank, and the Shimano Ultegra 9-sp cogs in the rear, with
an Ultegra rear 9-sp derailleur. I was just worried that the Campagnolo
Super Record clamp front derailleur cage would have enough clearance
to accommodate the chain when in the 34t chainring and smaller cogs.
I haven't purchased the crank yet, but wondering if I should spend
more $$ for a longer drop cage front derailleur as well. Just didn't want
to pay for shipping twice.

Not sure if the front derailleur cage drops far enough to clear the chain.

Usually both compatible and responsive, subject to various rear cassette
ranges, BB height, seat tube angle and probably the phase of the moon.

Do try it - Multi-step Ergos moving a double front on a compact crank
are usually just fine without buying a new changer. My own 36x48 shifts
great with a 1972 Campagnolo Record 1052/1. Current(1992 up) Campagnolo
doubles will almost always shift a 34x50 well, that's a common application.

Sorry, can't. I delivered the bike the other day in Chicago.
Indeed, you're right. There is a possibility of noise in the extreme
gear. I can't recall on that Gunnar if that's so but with an eleven,
probably. Our new bike assembly standard, set many years ago by Lorri
Spitz, is that small-small noise is OK but not second gear in. I
forwarded this to the bike's owner.

Beautiful Bike
How do you prevent being run over by a motor vehicle, during the
shoot?
The tubes of the Gunnar are so large as to appear to be alloy. Gunnar
doesn't make an alloy frame do they?
What brand & model are the rims & spokes?

Thanks, John

Nope, put on, lower FD, take a link outta yer chain(assuming it's
right for a 53/39) and go ride.

I personally had problems with an older Campy front derailleur. It
was a Chorus ~1991. It didn't have enough shape on the side of the
inner cage. It did shift 34-50t but it was a hard push and long wait.
Any newer Campy front derailleur (except CT) and Shimano fronts will
work better than what that 1991 derailleur did.

I have Campag Centaur 9-speed front & rear derailleurs. I trust the
seller of the new compact crank, and this is the only time in years
this shop was wrong. He told me that I would also need a new front
der. I went for the trial & error method, kept the old front der, and
lucked out. It's a gamble, but you win either way. Email me if you
want photos.
