Thank you for the additional pictures! Absolutely worth a look. The fastback stays and fillet-brazed joints make it really special.

BTW, there's a one recently posted on Pedalroom you might want to check out if you haven't already: TJ Quick Fillet Braised Road Bike.

The one in the Pedal Room is the same Bike.

Just picked up this beauty... apparently a builder from Florence who even supplied Bartali...

This a Simoncini Cyclocross Special. Simoncini is a small builder from Tuscany, Italy. It's a real race bike, with a stiff frame and quick steering. It's about as stiff as my Serotta Nova Special X which is built from Columbus SPX.

The ride is smooth and damp, perfect to my taste. Holding higher speeds is easy. The 48, 36 & 26 crankset is ideal for the 13-26 nine speed cassette currently installed. I can stay in the 36t middle ring from any speed up to 22 mph. The 48 ring is useful for faster rides, a tailwind or a slope. The Suntour bar end shifter are easy to use. The Challenge Parigi-Roubaix tires roll fast and ride very smooth at 105psi rear and 95psi front.

To be honest i am not sure how common this bike is, there is not much info online about them. not even sure of the year..

1980's Dancelli

I have purchased a 1950 Rondine (not an Olmo Rondine) from eBay seller Steelvintagebikes. It is equipped with a Campy Cambio Corsa changer and rare L.Magistroni crank, headset and Rondine marked seat post clamp, the only indication of its maker. No head badge or decals. I have found an image of a head and seat tube badge but that's it.

What is the history of Rondine? What can you tell me?

Thanks
Mark

My contribution--not exactly "rare", but I have only seen a few others, one in aluminum.

Simonetti was the shop expediter/parts guy in the original Masi CA operation; Mike Howard was one of the frame builders. According to the story, after Howard and Brian Baylis collaborated for a short time making Wizard frames, Howard and Simonetti teamed up (with backing from Bill Recht, who was also backing Confente) to make Medici frames at a lower price point than the Confentes. Flash forward some years, and it turned out that a prior Italian maker was using the name Medici, and they changed their name to Simonetti.

Filet brazed, late production (?early 90s?) and likely Tange O/S tubing according to an email from Mike Howard. (Frame has a decal stating 'Brazed by Mike Howard' on chainstay).

I guess Passoni certainly belongs on a thread like this...

That Passoni is gorgeous!

Ditto! KAS snagged a couple o' beauts from CdM this summer...

So this is a pretty obscure one-off, a '90 Serotta Custom CX race frame built by Greg Fuquay, a British expat building for Serotta in the late-'80s/early-'90s. Greg built this for himself---it was his personal CX race machine. It doesn't look like anything coming out of Serotta at the time, no tapered/squished/curved tubes, and the seatstay plugs are unlike anything I've seen on a Serotta. There's also no bottle/fender/rack bz-ons, and the cable runs go top/bottom to keep the inner triangle clean for portaging. It makes a nice all-around thrasher.

And since it looks like I haven't posted to this thread since 2013(??), a few lesser-seen builder bikes...

'78 Chris Kvale Road; fits 30mm tires w/decent clearance under short-reach brakes! Kvale is the King of Thinned Lugs:



'82 Columbine Sport Tour; 32mm tires under long-reach calipers:



'83 Mark DiNucci Touring/Sportif, reworked by Mark a couple years back, painted by Brian Baylis; 33mm tires under long-reach calipers:



'85 Peter Weigle Special Road; 28mm max rear tire/27mm max front tire:



'94 Nagasawa Road Special, display frame on loan from Nagasawa-san; these photos from last year's CR Weekend by Ken Toda:

Love that Nagasawa. Perfection, but only where it counts. Just right.

But what is that tie-wrap doing there?

Oh yeah...sorry about that! I was in a hurry setting this up for the show and my brake housing was a little undersized for the cable guides. The ziptie kept the casing from sliding forward, keeping a pleasant arc to the rear caliper. Not very visible with the bike up in a stand.

Thanks to the miracle of Photoshop, bye-bye zip tie:

Thank you. Much better.

Here's one more for the list: Araya. Though Araya rims are of course common, their frames are pretty rare. As far as I can tell, the company imported frames during the mid-70s to late 80s. I came across this one on Craigslist a few years ago; it's hardly a lightweight, but it makes a great around-town ride.

Well, here is Focus #2 , a 1985 I just purchased from new member 'Iowhat'. He bought it from the original owner in Ohio in 1986 and kept it pretty much original for which I am very grateful. Can't wait to pick it up this weekend!

There's a few obscurities in this CL ad: https://kansascity.craigslist.org/bi...633600643.html
I'd never heard of Gaikowski:


or Hennery Myers (I think this poorly treated specimen is the one, it's black as specified in the ad):


I've heard of Pogliaghi, but not much. This one is very fetching:



Bauer kind of sounds familiar, but I don't think they're very common:

Also, it's probably a good thing I'm going to be nowhere near KC this Saturday. This sale would break me.

^ My son lives in KC. Good thing all the bikes look too small for me.

OMG that Campagnolo Ford Cortina is so cool.. The old Beemer in the background is not bad either, and all those amazing bikes, and classy clothing..... this photo is full of win.

not really obscure around here...in antwerp

It is. I actually came across that car a couple of weeks ago:

[MENTION=173992]non-fixie[/MENTION], awesome, wow that Citroen behind is amazing too, thanks for the pic

I haven't seen Alpine on the list yet
Here's mine.
