HI all,

Sorry for the probably easy question - in pulling apart the 1978 Olmo, one of the pulleys in the Campy Nuovo Record rear derailleur is broken. I therefore want to replace both pulleys. Are these simple to source? As it turns out, the tires aren’t, so wanting to make sure I find some that are, to the best that I can, legit Campy pulleys that work with this setup.

Second - all of the brake cables could use replacing - same question - where? They are modolo brakes, hoods are already bought and replaced.

Lastly - I think the rear cassette is fine, but same question - if I wanted to find it, where would I go?

Thanks,
Ian

If it's your pride and joy, you may want Campy wheels for your derailleur. If you just want something that works and looks appropriate from 5' away, you can search ebay for "shimano ty05" and find these:

Shimano ty05 rear derailleur wheels $8

I use these Shimano brake cable kits.

Generally, the best place to watch for specific vintage components to show up is on Ebay Vintage Cycles. You might have to exercise patience, but sooner or later and probably for a pretty pricey price, you will find what you want. However...

If you are worried about the bike working and not a stickler for original issues componentry, then, as mentioned, most Shimano idler wheels will work, just fine. And for cables, unless original is the only answer, just get a set of STI cables which are many times better, from a functional point of view, than the vintage stuff the OP is talking about.

It's nice to have all original spec on your bikes but it can prove to be very costly and won't add any real value to the bike unless it's top tier, grail stuff.
If you want to service vintage bikes, there's no better value than a cheap membership on this forum, giving you all-access to the Buy and Sell where you can source out the parts you want.
The bonus is the warm and fuzzy feeling you get, when your freewheel (likely not cassette) arrives in the mail!

Some Campy parts are really well built. Jockey wheels aren’t on that list. About half I find are cracked.

Even cracked, I've found they still work as intended. But they just don't look very good. Sometimes, they're cracked on just one side and you can hide it by flipping it around or using it as the jockey/upper pulley.

^^^ careful application of JB weld if aesthetics are of concern...Not being a manufacturer/numbers caring person I just ride with the cracks or use the Shimano wheels.
Gets me where I want to go, Ben

The fact that Campy jockey wheels work with a crack is pretty nifty. I was wondering if using a glue would change performance much if carefully shaved down. Then you could "paint it black".

repechage

way back cracking plastic was not a problem, but that was 40+ years ago.
I have exchanged to any number of sealed bearing pulleys, Velo Orange, Bullseye, Forte (a Performance house brand... those must have gone somewhere)
Somafab also has replacements.

Salamandrine 

Exactly. It simply didn't happen. It's silly for people to insult campy jockey wheels that are 40 years old. Most plastic things that old are prone to crack.

Lots of people used to put on Bullseye wheels -- usually red, for that extra low friction (supposedly). So really any semi modern anodized wheel that looks kind of like those will still look period from a few feet away. SOMA replica wheels are probably the closest for a pure original look, if the OP wants to spend $35.

WRT the cables, nothing much has changed all that much. A regular modern road cable will work fine. This was the before the lined housing era, so grease the cables heavily before you put them in the housing. Technically they don't need to be replaced unless they are frayed or damaged, but at this point they would need to be pulled and greased, and it's likely they won't go back in easily, so just replace with new.

WRT the "cassette". It's a freewheel not a cassette. For and Italian bike, a Regina or (less common) Everest is most appropriate. Probably italian threaded. Could be 5 or 6 speed. Get the right one. Unless the bike's been ridden big miles, probably doesn't need replacement.

Think about this:
NR pulleys are always cracked.
Valentino pulleys are never cracked.
Go figure.

That's sorta like all my Campy t-shirts are faded and worn, but the Oral Roberts U t-shirt my sister gave me years ago still looks new.

Probably because bike owners replaced the Valentino with Nuovo Record RDs as soon as they rode it a few times...

Wow, thanks for all the responses! I have been up to my nuts in Covid crap, but hopefully I’m going to find time next week to figure this all out!

Macdian you are probably running a freewheel and not a cassette on your bike. As soon as you reach 10 posts you can add pictures. Closeup ones of your freewheel can assist with whether it needs service or replacing. How your bike shifts can be an indicator of the freewheel's condition. However, first concentrate on the jockey wheel and pully. Eliminate the obvious first.

Macdian

pastorbobnlnh that sounds great - I’ll do that shortly. I’m actually not trying to “fix a problem” right now - just basically replacing almost all “wear parts” that need it - with the wheels being cracked, they were on the list. So far I’ve re done the hubs and rims, hoods, tape is off, and we are about to pull the bottom bracket to see how it is and re lube it.

I actually can’t even ride right now. Had back surgery 3 weeks ago!

Macdian

Those bullseye actually look pretty good. What I really need to do is decide if I’m going to try to go all original, and keep the paint, or upgrade stuff where needed, and maybe even paint the frame for fun.

pastorbobnlnh Here are pics of the rear wheel.

clubman Good call! I didn’t even know there was a membership, and that it’s dirt cheap! Bought it!

pastorbobnlnh 

Macdian your Regina Freewheel looks to be in good shape. If you find it shifts well, no worries. It does look as if it would enjoy some time at the Spa! However, I'm on sabbatical and the Spa is closed until mid-July.

My "go to" replacement for Campagnolo Record jockey wheels are the Suntour BP-100 wheels, standard on Superbe Pro derailleurs, they have little brass bushings that allow them to correctly fit the Campagnolo bolts. There a complete no hassle bolt in installation with out the faffing about with Bullseye and their spacers.
