Calling all Campy Enthusiasts!
 

I want to install a Campy Record Triple crank on a road bike, and Campy recommended a Record 111 mm Asymmetrical BB for it. Does anybody know the offsets of that BB, versus say a Record Pista BB? These are both cartridge BBs. Neither are cheap, but the track part, which is supposed to be symmetrical, is much easier to find.

I measured this once about 100 years ago, but I can't find my data.

Why not just do what Campy recommends?
Seems simple: Veloce, Centaur BB in 111mm and call it a day. I have one.

Old Record triple as in late 70's 80's or newer 90's Record triples.

It can't be the old one. It takes a much longer spindle.

EBay is a great source for hard to find parts.

Will this work?

Robbie is correct. You can use a Centaur 111, which is less than $50 at Ribble. Buy a couple of chains or a cassette, you get free shipping (over $100).

I would probably do a test-fit with any 107mm symmetrical JIS cartridge bottom bracket.

The juxtaposition of shorter length and symmetrical spindle with the (effectively longer) JIS taper will probably be close (if not better) than what a Campag 111 triple spindle will do.

A 1-2mm spacer can be used, as needed, to offset any cartridge bb that has a driveside flange/shoulder.

???? Jury-rigged setup instead of what the manufacturer recommends? How in the world would that be better?

Let the flames begin! ��

Not trying to start anything, but the proper BB with the correct taper costs all of $50, no spacers, no mixing JIS and ISO, just plug and play.

Once you use that JIS BB forget using anything but a JIS on the Campy cranks , ask me how I know.

It just so happens I have today threaded a Record 111 mm BB (carbon body) into a frame and test fit a Record 10 speed triple crank to it. Fits perfect, as you'd expect. I bought the BB used on eBay, wasn't too hard to find.

Those of us who appreciate Campagnolo consider ourselves Campagnolo Enthusiasts.

Because Campy doesn't know anything about your frame measurements, your rear wheel, or how it's dished, etc?

But I don't either, FWIW :P

I'm a freak, but I'm certainly not freaky enough to answer this one.

I agree. Been there. Usually makes itself apparent in about 50-75 miles.

Judging from the OP's bikes, it's safe to assume that the tubing diameter is 28.6, it is also safe to assume that the wheel will be dished properly. It's not rocket science, and Campy does know how their stuff works.


Some people:roflmao2:

Here are pictures if it helps the OP.

This is Record triple crank on Record 111 mm BB. BB is symmetrical as best I can measure. FD is Record - double I think - with limit screws backed all the way out. I dunno if the FD will work but a triple FD would.

Here again, if the chainline now needs adjustment to get the front derailer to pull the chain reliably down to the granny ring, one can just add a driveside spacer under the fixed cup.

As for the JIS rec, I wouldn't mention it other that that I don't know if this frame is 130mm as was intended for use with that crankset, and I myself don't like a triple crank being offset any more to the right than is absolutely necessary to achieve chainstay clearance and robust downshifting on a particular frame.
The JIS cartridge is also something that I always have around in every length available, so makes for a quick conclusion to the question of how much "chainline" (defined dimension) is actually needed to use the particular crankset on a particular frame.

The older Record Triple symmetrical bb is a great choice here, as it is adjustable for minimal-required chainline simply by adding a thin cup spacer as needed.

I don't know what problems people have had with using JIS bb with a Campag crankset, but I've had production bikes that were so equipped originally, and gave no problems over thousands of miles of hard use.
I actually measure spindle tapers, so I at least know what kind of taper I'm installing and what effect it will have on the effective spindle length. I have never had any problem with chainring runout or durability using this combination, this coming from someone who will not consider using a titanium bb spindle, which can cause issues far beyond anything I can imagine from using Campag cranks (any vintage) on JIS bb's.

You people over complicate things. The OP clearly stated a Record triple and a cartridge BB. Even though he didn't stae explicitely, one can safely assume at least an 8 s, if not a 10s setup. His frames in his sig are all steel 28.6 OD tubing. A $50 Centaur BB will work just as well as a $100+ Record. There is no need for spacers, mixing tapers or anything else.

@ Miamijim: it's a newer '90s or early 2k's crankset; the chainrings (original) are 10-speed.

@ Robbie: What Campy recommends is exactly what I said for the Record triples, in the literature I have.

[MENTION=30418]Highgear[/MENTION]: That link you found to Velomine is the part I am looking for. Because of the price, I want to see what the "special nature" of the Asymmetric part is and if it is significant for this bike.
[MENTION=346401]jiangshi[/MENTION]: I don't want anything started here on my account, so thank you for that sentiment. I seem to get into trouble on BF more often than not these days. But, according to Campy, the proper BB is the one Highgear linked to, and it does not cost $50 from the Ebay "dealers," only from some less experienced private sellers. I have a 111 Centaur (the black one), and it has a large offset. Is it the same as that of the Asymmetric? I don't know. I've been watching Ebay for these parts now for about 6 weeks, and very few Asymmetrics come along, compared to the Record Track model which is also 111 mm.

The bike is designed for 650b Hetres, and has very wide chain stays. I've done several test installations of a variety of cranks so far, and it can be difficult to fit a crank with correct chainline and good clearance to the crank arm ends. I want correct chainline because I've found it can affect shifting quality.

Jiangshi, I totally agree with you about not mixing tapers. I have done so in the past with no terrible effects, but those were cheaper parts that I didn't care much about. This bike is rather special and I'm being careful with it.

Road Fan, As I said, if you want to save a few bucks, the Centaur BB from Ribble will work fine. Buy a chain, a cassette or other consumables to get the cost up to $100, and you get free shipping. I have been getting deliveries in 5 days, or less.

What sort of build are you looking at, and on which bike?

Edit: I see we cross posted. I'm running a Centaur BB on my wife's bike (De Rosa Professional) with a Chorus triple. No issues whatsoever.

My apologies! Campy Enthusiasts, of course! A beer on me for all Campy Enthusiasts! A second one for an Expert who can actually answer my question!
