Subject: Campy CT cranks - is CT fr der required?
|
I'm going to be installing Chorus UT CT cranks and am trying to get a
straight answer as to whether I "need" a CT front derailleur. I've gotten a
mix of anwers from other cyclists, online retailers, and LBS people, so I
thought I would turn to the ultimate authority, Usenet. So...can I get away
with my existing Record 10sp fr der? Or should I give it a try and if it
doesn't work too well, then maybe go for the CT front mech.?
Associated question - if I do go with a CT front mech, can I use the new QS
derailleur with my '03 Record 10sp Ergo shifters? Or will I have to either
track down a 2006 (pre-QS) compact front mech OR replace/upgrade my left
Ergo lever?
Thanks much in advance...

Man, count me in the "only use the standard double FD, period" camp.
I bought a 2007 Veloce CT group from Eurobikeparts.com for my new
Guerciotti, and it shipped with a standard FD. I contacted them and
asked how to exchange it for a CT one, and they were apologetic and
overnighted me a CT one, and a prepaid box to ship the standard one
back in. (Great service, those guys. Recommend them highly.)
Turns out, I should have left well enough alone. The CT FD had to be
adjusted VERY carefully to keep the outer plate from hitting the
crankarm, and even then would balk at moving the chain. Half the time
the chain would stay on the small ring. A quarter of the time, it
would throw the chain on the outside. The other quarter, it would
shift like I wanted.
I wasn't a fan of the "escape mechanism" shifters, and wanted to get
rid of them anyway. I hoped that maybe by having the micro-indexing
shifters, it might fare better. I got the pre-QS Centaur Ergos Nashbar
had for $120 to get my loud, tangible clicks back, but I still
couldn't get the front to shift well. I tried both the standard cable
routing and on the other side of the bolt, no luck.
For fun, I pulled the standard double Centaur FD off of my PX-10, and
bam! Shifting works great. No worries about crankarm clearance, shifts
every time, doesn't throw the chain, just better all around.
I got a pre-QS Veloce double FD off of ebay for $30 and life is good.
I got $20 for the CT one (and $60 for the QS brifters) at Recycled
Cycles. I feel like my build is complete.

Why bother with a good starting point in general? Why not just put
the new crank (assume 50-34 rings as opposed to the old 53-39 rings)
on the bike and put the chain around the big-big ring-cog combination,
run the chain through the rear derailleur, and see if it is the right
length or how many links to take out?

Thanks to all who answered - I am going to try using my existing front mech
and see how that goes before getting into a CT front mech - as Qui si parla
Campagnolo stated, "Remember compact cranks were around way before compact
Fders..."
I do have one follow-up question though - obviously I will need to go with a
shorter chain - is removing 2 links a good starting point in general?
Thanks again!

I replaced my Shimano FD which worked fine with my Chorus UT CT crank but
was going to go all Campy anyway so picked up a non-QS Centaur CT FD. It
seems to shift a bit quicker than the Shimano but also seems more touchy to
setup. Chain rub is more common than before. However, I can now forgo the
chain catcher as the CT FD never seems to drop the chain.

Unless the crank is a non Campagnolo one, then use a double FD. The CT
works poorly with FSA CT cranks particularly.

I have been using a rather elderly Record front derailleur with (now
~2003) Ergo levers and ultra-compact cranks -- specifically, 94mm
mountain bike cranks, used as a double, with 46/30 rings. Works fine.
So, it is certainly worth a try.

The only advantage of the compact derailleur is that the bend of the
cage is closer to the shape of the 50-tooth big ring, and possibly the
inner part will be lower to more effectively engage the 35 tooth inner
ring. Nothing about the shifter will matter, except that it should
shift more cleanly. Replacing the lever will be an expensive
proposition, and will be unlikely to gain you anything.

There is no snappy answer for all riders.
Manufacturer's recommendation is 'buy a new CT changer'.
We know that works. Absolutely with your Ergos. If you aren't troubled
by another $50~$126 part and need certainly just get a CT changer.
In our experience a Campagnolo double front will almost always shift a
CT crank OK, satisfies 3/4 of new compact crank customers. You may find
the shift response quicker with a CT changer than with a double changer
but riders' expectations vary quite a bit.
I'd set it up with your present double FD and ride. You can always buy a
new front changer if you expect better response than you have.
In our experience just about any front, any brand, is fine with
infinite-step left Ergos. For the new 'binary' QS Ergo, doubles/compacts
present few problems but triples will usually require all-matching
equipment. Be not afraid, it's easier than it looks.

Yes, it will work just fine. Remember compact cranks were around way
before compact Fders...

Just use the standard FD, it will work fine, what we have done on
dozens of setups.

If ya gotta use a CT FD, sure, use the QS one. Any FD will work the
'standard' left ergo..like you have.
