I recently posted a thread asking for advice on classic Road triple (52/42/30) cranksets, and I received some good suggestions. It seems like vintage doubles are more abundant than road triples. Who still makes triple-izer rings that would fit vintage Campy stuff like Strada? Peter White cycles does not sell them anymore.

Thanks

I don't think that's going to work on a vintage Record Strada crank.

151 BCD. Right.

Could contact the OP of this thread:

I was thinking 144. I think 151 is pretty rare. I've never seen one.

Elliott Bay Bicycles used to have a jig and would drill Campy 144bcd cranks (NR/SR) for a triple. Might check with them.

I was just going to suggest this. Campy expected most of their customers to just HTFU when the hills got steep.

No, you were expected to be strong enough to turn a 42.

Way back, no self respecting racer raced with anything lower than a 21. The view was, if you need lower, you were off the back anyway.

Thanks for the info so far. So it seems that triple-izers are perhaps harder to find than triple crank sets themselves thus being counter productive to find a double and a triple-izer instead of just looking for a triple.

Alternative: third-step triple with regular road double crankset and long stackbolts, a big freewheel/cassette, and a long-cage rear derailleur, e.g:
48-45-42/12-15-18-22-26-30-34

Isn't that what I said?

Indeed, the old Italian racer that I just bought is 52/42, 13-21 7 speed.

Then while your getting your Record crank arm drilled out by Bob Elliot at Elliot Bay Cycles. You can pick up one of his awesome CNC'd Rally cages for your NR/SR derailleurs. Merz made a 144 adapter that you used to be able to get from Harris Cycles or maybe even Peter White.

The other problem with going the vintage Campy NR/SR crankset option is finding a triple bottom bracket. These use the thin cups, not the thick which are usually used for doubles. Not sure what you are intending on putting this on, but a spindle for English (68mm) just went on ebay for around $19, so they are out there.

If you don't care that much about period correctness, but still want Campy, take a look at their Racing-T triples (usually 52/42/30), which can be had fairly cheaply used (ebay, etc.). You will need the BB as well (Campy AC-H or the Centaur BBs will work for this, 111mm IIRC).

Except for the more intelligent ones, like Jacques Anquetil in 1963:

According to some sources Anquetil climbed the Forclaz with 42 x 26.

Perhaps he was one who used half-step in the flats and 1.5-step in the hills, requiring a change of only the inner chainring. Been there ... done that:

50-47/14-16-18-20-23-26 for flat land, 50-42/14-16-18-20-23-26 for hills

With only 5 cogs, he ran:

50-48/14-16-19-22-26 (source: The Dancing Chain, Frank Berto),

50-42/14-16-19-22-26 (consistent w/ reference in post)

TA made a triple-izer for the 144 cranks, but I think they're long gone now.

Yeah. 151 was Record, (pre-Nuovo Record) cranks.

?

I have an old Italian racer that came with a 54/51 up front, and a 13-21. Five speed. Early 60's, when men were men.

I know what they are. I've just never seen one in person.

There is no such thing as a Nuovo Record crank. They're all Record with either Nuovo Record Or Super Record rings.

Yes, TA has discontinued them, but I may be making some copies of their 144 triplizer by early next year. I'm going to be selling my 122 bcd triplizers (which are now polished) through a Web site that I will have in operation by the end of this month. My other product at this point is a 37-tooth 122 BCD ring in the Stronglight 93 pattern, which is a copy of a chainring that Stronglight once made in very small quantities but (from what I've been told) never listed in its catalog. The smallest "official" size was a 38. This gets you one tooth lower, which is as low as you can go without a triplizer.

While technically true, (although I am kind of snagged on the term Nuovo Record rings on a Record crank) back in the day (1970's) Nuovo Record was applied by bike shops and the interested public to denote the top tier Campagnolo group.
"Nuovo Record" cranks were the 144 BCD units with the bottom bracket that had the reverse "threading" in the sup bores to help expel crud.
We shop rats knew that there were exceptions, that triples and Pista bottom brackets still used the thin cups, and probably due to old inventory many French bikes in the 70's still had the thin cup bottom brackets installed, think LeJeune for example.
Nuovo Record was the shorthand way to describe essentially a top tier equipped bicycle.
Then there were the minor upgrades before Super Record, the Superleggero pedals and seat post.
Later of course Super Record arrived which made things a bit more messy and strengthened the "Nuovo Record" bike shop shorthand label.

In the 80's shops used the term "Super Record Reduced", which was not a Campagnolo catalog term but stood (but some distributors used) for an ensemble with Superleggero pedals and the steel spindle Record bottom bracket.
The Racer's choice until Shimano 7400 arrived.

Please do. that will let me set up a triple on the Signature 290s so I can ride it on a 180 mile charity ride in June.

The Trek Across Maine, yes? I've always wanted to ride it but never have. I'm holding off on the 144s for now because I'm a fledgling entrepreneur, and hence reluctant to go too far into the red making triplizers until I see how many I can actually sell. If and when I break even on the Stronglight triplizers and 37-tooth conventional rings, I'll dare to go ahead with the 144s. I'm hoping that could happen by late winter, but that's just a wild guess.

Trek Across Maine, yes. It's a great time and a good ride. This year will be #8 for me.
As a fledgling entrepeneur, I would think that there are more 144 BCD cranksets out there than Stronglight. just saying.....
