OK, this is an old chestnut which has probably popped up on r.b.t umpteen times, but all feedback
will be gratefully received. Basically, I'm about to take the plunge into the world of Campag 9
speed; I'm intending to use 9 speed levers and a 13-23 block (all Mirage) with a SRAM PC59 chain and
an Avanti 8sp. derailleur which is fitted with Tacx 9sp. pulleys. Am I likely to experience any
major shifting difficulties?

Thanks in advance, David E. Belcher

The usual answer here is that your derailleur will "work fine" but I didn't have such luck when I
tried it with 2003 Mirage 9sp Ergos (also coincidentally with an 8sp Avanti with Tacx pulleys...
lime green ones of course!) - the indexing was slightly out (and Campag pulleys didn't help). I
suggest giving it a go, though, and then buying a new mech if necessary. A Xenon will keep the cost
down and'll work just as well as a pricer model.

9s groups and compatibility: Rear derailleur


Does the 8s rear derailleur work in the 9s drivetrain?

No, because of dimensional and excursion problems.

Nonsense. They just want to sell you a new derailleur.

It is not nonsense, they want you to have something that works well, properly, not just barely good
enough if that. 9sp derailleur geometry changed in 2001 and is different to 8sp.

There are two different 9 speed Campy systems. Pre-2001 that will shift with 8 speed and pre-2001 9
speed rear changers, and then 2001+ Ergo levers that will shift 2001+ 9 speed and 10 speed changers.
You need to find out what year your Ergo levers are. If they are 2001+, you can either change the
"guts" or you can buy a new rear changer.

Wrong. Supposedly the new derailleurs are different from the old ones, though people with experience
(Such as Peter Chisolm) will tell you that they will still work with either old or new shifters.
But, the OP was changing 8-speed to 9-speed; that is, had an old shifter. There is no functional
difference between a pre-01 8-speed and 9-speed rear derailleur, so his 8-speed will work just
peachy keen with 9-speed shifters.

Excuse me, I have experience with exactly the components the OP intends to mix and I know that they
don't work very well together. I refuse to be bullied into agreeing with Peter Chisolm on
everything!!

The OP in *this* thread did not say that. I think you are getting mixed up with another thread.

David Belcher's post implies that he hasn't got the levers yet and will be getting NEW ones.

You're right on that. Mea culpa.

No, he said that he would be getting 9-speed levers. If he is cobbling together the components he
lists, it might well be that he was planning to get the levers at a swap meet. I am not clear as to
whether _any_ of the new levers/shifters that Campy claims to be incompatible with the older
components are 9-speed, or whether all of that it 10-speed.

Maybe Peter, or the OP, can shed some light. In most things, though, the official Campy site goes
overboard about what stuff you have to replace in order to upgrade.

If the cogset is 9s, it should work fine and dandy as long as nothing is worn out. No need to fit 9s
pulleys, BTW....

Changes were with 9-speed only. Both the 9sp shifter cable pull and derailleur geometry changed in
2001 - I suppose to simplify and economise on manufacturing: 9 and 10sp deraileurs are now virtually
identical, etc.

Old 9sp: 3.05 mm pull 1.5 ratio 2001+ 9sp: 3.20 1.43 (same cog spacing) 10sp: 2.76 1.5

Sounds promising. Most of the bits have had less than a year's use, incidentally, and have been
sitting around in my collection of odds, ends and spare parts for ages. Incidentally, the levers are
the '99 model (before they changed over to all-plastic construction), whilst I've yet to buy the
cassette and chain. The levers have already been purchased, but I'm not allowed to get my mitts on
them until Dec. 25th (condition laid down by Mum & Dad!) [1].

> No need to fit 9s pulleys, BTW....

It didn't have the original pulleys for some time anyway - they were swiped to keep another rear
mech going!

Thanks to everyone for their input so far, by the way, I'll see how it all works out, and shell out
for a new Mirage mech [2] if the current set-up is doomed to failure.

Regards, David E. Belcher

[1] Yes, I may be 29 in a few months' time, but being a cyclist still allows you to get flashy new
'toys' for Christmas for an awful long time. Mind you, I only managed a pair of Cannondale track
mitts last year :-(
[2] A favourite of mine, by virtue of the smart black & silver finish
- reminiscent of the excellent but extinct Mavic 841.

Best not to get a new mech then. A pre 2001 one would work best if mech does ever need replacing for
some reason.

Sorry for assuming levers were going to be new ones.
