Need advice -- front derailleur for Nuovo Record triple crankset?
 
Hello all,

First off, I want to thank everyone for the very helpful answers I received to a couple of previous queries. I am in the home stretch of a bike project -- I just handed over all the parts to a local bike shop this afternoon and told them to get to it.

Basically, I'm taking a really good 1981 Dawes Atlantis frame -- made of "531" steel, the sort of high-end frame where the buyer specified the components -- and I am replacing all the current fair-to-middling components with period-correct Campagnolo Nuovo Record parts (with a couple of exceptions).

My question today is this. Do I have the right front derailleur for the Nuovo Record triple crankset?

I have a totally-stock Nuovo Record triple crankset that (according to the guy I bought it from on eBay) came from a 1979 Schwinn Paramount.

I did a lot of reading on the web, and found plenty of information about the REAR derailleur I need to use with the triple crankset. Apparently I need to use a "long cage" derailleur, and the one manufactured by Campagnolo for that purpose was the Rally derailleur. I have acquired a 1st-generation Rally derailleur, so I should be all-set there.

But what about the front derailleur? I haven't seen anything indicating that a special front derailleur was used with the triple crankset, so my assumption is that any Nuovo Record front derailleur will do. And yet -- I see that in later years there was a differentiation between front derailleurs used with standard two-gear cranksets and the more-exotic three.

I also have a totally-stock Nuovo Record front derailleur, probably manufactured sometime in the 1970s -- there aren't any holes in the cage that holds the chain, anyway, and I guess that dates it. (I'm not sure if "cage" is the right word for it, but I figure people who know this subject better than I do will understand what I am talking about -- you know, the flat and shiny metal part that goes over the outer edge of the chain.)

So -- is this the right front derailleur for this kind of set-up? Is there some sort of standard modification that needs to be done, or is it OK as is?

(BTW, I'm going with vintage SunTour bar-end shifters, and with Campy C-Record aero brake levers, but all the rest is Campy Nuovo Record equipment. I'll be using the Nuovo Record high-flange hubs, but I've been thinking I'll let the local bike shop advise me on new rims.)

For many years (minimum of 10 if I read correctly) after the introduction of their triple cranksets, there was no special front changer.
We mechanics got pretty handy with tools we used to manipulate (bend) the chain cages so triples (and many doubles) would run.
After increasing feedback from the field, Campagnolo came out in the mid-80's with the first triple front changer I'm aware of.
Having said that, your Nuovo Record front changer is totally correct for the setup - it just may not shift as well as some others.

Thanks so much! This was the impression I got, too, from reading the literature. But nowhere is it spelled out!

The LBS should be able to suss this out. Part of what you're paying for-LOL

You should be fine with the NR front provided the triple crank has a 36 tooth inner ring. It is what I used.

Olympianrider 08-03-16 11:01 PM

Yes, it has the 36-tooth inner gear -- probably not optimal; I would have preferred 30, but at least it is original and it should mate with an original front derailleur.

Meanwhile, I did get the call back from the LBS yesterday, the one explaining to me how much it all is going to cost, and well, once I recovered from my shock and told myself, at least it's still going to cost less than a new bike -- they darn well better handle tricky questions like these!

Framebuilder Jim Merz offered 30T and 31T chainwheels for this chainset.

You could do a saved search with ebay for these.

This is a good option, but takes some attention to detail to get the chain length exactly right (no slack in small/small position while not too tight in large/large position).

I would imagine these to be the very definition of "hens teeth" as Jim would say. ;)

Olympianrider 08-05-16 11:24 PM

Wow, that does sound like a terrific option -- trying to locate a smaller inner gear for the crankset -- but I'm afraid it's out of the picture for now. I handed everything over to the bike shop last weekend, and the bike is in the upgrading process already. Need to get it ready for a 400-mile ride in September. Man, it's not going to be cheap. Getting custom wheels done is a little spendy, but the high-flange hubs will really set it off. I guess I've wanted an all-Campagnolo bike since high school, and the one I wanted in high school is pretty much what I'm getting now.

I dig your last sentence. Cool.

By the way, let me know if you need a Record front derialleur, for cheap.
I can probably fix you up.

Edit: oops, I see you don't have enough posts to send private messages yet.
I'll send you one.
