Bike identification - Castiglione

[Nob]

Not sure of the difference between the two versions but had it's own Columbus seat post. Aero tubes are stronger in one direction but weaker in the other especially on the down tube which is prone to flex from bottom bracket forces. Reynolds used a thicker gauge tube, Columbus stuck an extra tube in the down tube.

Would love to get my hands on another set of these

As I got this done with the last set I got hold of

The Strom fork dropouts are from a local manufacturer, so now I'm pretty positive about it not being an Italian made bike. I've asked about on that forum at the sellers, they may know something.

As the Artigianale model I can't recognize any similarities between the models in Argentina, but the Argentinian models share many similarities.

I think we're getting close...


Edit: I've reached out to a btt forum user that made a list of Argentinian frame builders and he mentions Castiglione. His last seen on the forums dates back to 2017. Not holding much hope.

Great to have that list of Argentinian builders and it affirms both Castiglione and Julian Rico which I previously mentioned. I have another line of enquiry outside of the BTT Forum which may help with further info. I will let you know if I receive further details. Sometimes people reply/sometimes they don't!

IIRC the first iteration of 'Air' was fork blades and seatstays, no proprietary seatpost, certainly the 1st Gios Aerodynamic utilised Columbus Air and were fairly standard frames fork legs and seat stays aside. It did get more involved later on though, as per the tube set you show.

This Pinnarello has the centre section of the main tubes ovalized then back to round into standard lugs and seat post. I have a Specialist Bicycle Development Unit Raleigh Dynaflite 753 built in the same way, the only one that is known to exist.

Hello frens, I've just recently bought this bike. Seller couldn't tell me anything about it nor was I able to find anything about it online either, which makes me much more curious.

It looks, to my untrained eye, pretty high end except for the groupset that's not - full Shimano 105 1055. It has Columbus tubing, both frame and fork. Fork has Strom fork ends. The dropouts are also marked but I'm not able to read it. Another interesting frame detail is the quill seatpost. The seatpost itself is Shimano. It also has internal cable routing for rear brake and downtube shifters.

The only other identification besides Castiglione stamped several times, is on the inside of the non drive side chainstay, seen on the pictures.

Thank you.

Very nice and interesting frame, can't see any seat clamp bolt, does it have an expander bolt seat post.? You say that the forks and seat stays are aero so all the main tubes fully round.?

Yes, it's a quill seat post design. Makes the seat stay cluster really clean. All the main tubes are round.

Yeah it looks really neat and minimalist, my flat stays have a bolt running through..

That is one sexy bike. Congratulations on this incredible purchase.
I hope you've got the guns that this racing machine deserves!

The top tube internal cable routing looks similar to my Columbus TSX frameset from late 80s.

1980. Columbus Air was the Italian manufacturer’s initial attempt at an aerodynamic tubeset. The intial version used a teardrop shaped down tube, seat tube and seat stays in conjunction with an oval top tube and chain stays, and a round head tube. Later versions had teardrop shaped chain stays. The tubeset was designed primarily for time trials and aerodynamic efficiency and therefore it is not practical to compare it directly to other round Columbus tubesets. Due to the teardrop shapes the resulting frames weighed more than SL, but had less strength. The rear triangles in particular had a reputation for being whippy, due to the thin seat stays. However, this was considered acceptable given the intended TT use and aerodynamic advantages.Of particular note, the seat tube came in two versions. One with a standard round top end, to accept a normal seat post and another which carried the teardrop section right to the top, requiring a teardrop section seatpost. If you have the latter, you may have some difficulty finding a seatpost, unless it is provided with the frame. Most frames built with this tubing were outfitted with Shimano Dura Ace AX, or less likely, 600AX.

What a lovely frame! Very nice catch.
I absolutely love the seatstay construction. With the quill post and the inner faces painted it makes for such an elegant, sleek junction.
Really deserves a gentle renovation and a rebuild with some higher spec components.

I've found another frame by the same builder posted on the classifieds. Same town that the others were found. Pictures are really bad, but there are differences between this frame and mine. There's a seatpost clamping bolt, it has horizontal Columbus dropouts.

"KUCZORA" is stamped on the inside of the driveside chainstay, along what appears to be a serial number: 11 079 247. Maybe a year? Looks like a month-year-frame but I don't think so, mine reads LE 4 456 047.
