Campag 9/10sp chain on Biopace rings?

Yes, I use a SRAM 9-speed Powerlink with Campag C9 chain with no problems. I like them so much that
I wouldn't not use one now. Only 50p!

There are also some new connecting links from other brands (Connex, etc?)for some 10sp chains - but
I don't know much about them. I'm still a 9-speed geezer.

Some thoughts while you're waiting for the Shimano experts: I would guess that a C9 chain would be
ok on Biopace rings if a Shimano 9-speed chain was. I doubt the egg-shapeness of them should make
any specific difference when it comes to brand of chain. Widths are different but not hugely.

Ah, that's handy to know, ta. Thinking about it, I realise I may have a spare 9sp powerlink hidden
about the place somewhere....

Yeah, it was the width that concerned me. I guess that Biopace was intended for 7 or maybe 8 speed
chains (?) so don't know if a narrower 9 will mesh at all. I don't need extra slick gear changes at
the front, until I upgrade the other bits to campy 9 I'm happy if it's a bit clunky so long as it
actually functions alright.

There's little difference in *internal* width between 7, 8 and 9-speed chains so it should mesh.
It's the outside (overall) width that varies more - and would be more of a problem on rear sprockets
than chainrings if anything.

From Barnett's manual: "Most 6 speed and all 7 speed sprocket sets require "narrow" chains with
outside width of 7.2-7.4mm. these chains are adequate for most 8 speed sprockets but may be slightly
noisier than the "super narrow" chains which are always 7.2mm. wide, these can also be used on any
other sprocket sets. Nine speed chains measure 6.6-6.8mm. and they can also be used on other
sprockets."

SRAM PC59 chain also works well with Campag 9-speed stuff and is cheaper - although I'm not sure if
it lasts as long as C9.

I didn't know that. I'd assumed a 9sp chain would be narrower in. and externally. Sounds good news
then. Thank you Pete.

Need to replace most of the drivetrain on one of my bikes. I've never used any Campag stuff and
would like to give it a try, see how it compares with the Shimano equipment I'm familiar with.

So, I'm having some wheels built up on Centaur hubs and intend run them with a new 9 or 10sp
cassette, chain and front 'n rear mechs. Will the Campy 9/10sp chain run okay on my existing
Shimano Biopace chainrings? I don't think wear will be an issue, the front rings seem in good
condition I just don't know if they are at all compatible with a Campy chain?

I'm going to be using downtube friction shifters for the moment, if that makes a difference (I
don't think it should?).

Also, this has just occured to me, I'll go and google for it in a sec but might as well ask while
I'm here... can I get a powerlink type connector for Campy 9 and 10 speed chains?

Yes but you might just buy a snaplink-enabled brand of nine speed chain to start with. (Here, we no
longer use Campagnolo chain on new bikes.)

No issues with the BioPace unless they're worn.

Well a C10 chain works fine on TA Cyclotouriste rings, which are a much older design. The teeth on
those chainrings, are, according to my vernier calipers, 2.1mm thick. That's compared to 1.94mm
thick for a chainring that explicitly states that it's 10-speed compatible.

Sounds good, thanks for the info (also to other posters). I've ordered the bits now so it either
works or I'm buying a new chainset.

The dealer actually had some slightly old stock oft new Daytona chainsets for just 40 quid, which
I'm very tempted by anyway, I've resisted for now....

Yep and don't need a new front mech.

Sram gold for 9s, Whipperman for 10s.

This seems to be a new "standard" for 3/32" sprockets.

I noticed that my new spare SRAM 3-spline sprocket for my Spectro S7 internal-gear hub looks thinner
than the previous ones I'd bought (both 3/32" nominal). My measurements roughly agree with yours.

Hopefully the metallurgy has improved so that there's no accelerated wear.
