Help with 80-90s frame serial number
 

Hello! I recently got a 80-90s bike with destroyed original paint and not a single decal. A previous owner rattle spayed it and I can only tell it was originally white without any chrome on the fork or frame.

I want to restore it but the serial number is the only straw that I get. I wish I could upload photos but since I am a new member there is a 10 post restriction so i will describe it the best I can.

The fork dropouts are Campagnolo and there is no engraving on it or any logos. Its a whole piece with smooth angles and no additional details or ornaments.

The frame dropout are again Campagnolo. The speed wires go above the bottom bracket and there are holes for just one water bottle around each is a 4 angled star shape. The cables for the rear brakes goes into the center tube via 2 extruded holes with a star shaped elements.

On the bottom bracket I could find only one circle hole and nothing more. The lenght size is 68mm and the diameter is 38-40mm

There is a cube shape on the frame where is the bolt for the rear brake.

I found a serial number on the left side of the frame near the seat post which says 364152 and it is engraved into the ornament that connects the central and vertical tube before the rear tubes.

At the bottom of my profile here you will google drive link with detailed photos :))

I will be very happy if you can provide further info because I want to repaint and restore it to its original beauty and style!

Seems to be a TT bike of some origin, but looks rather general to me, so the smarter than me might be able to be more of a help.

Those holes in the bb shell look very concerning.

Interesting combination of internal cable run and over the bb cable guides. Makes me think the top tube has been modified.

Intetesting braze on for the fd.

I looked through internet and think that the frame is middle class Columbus Aelle with 26,6 seat post size from an italian builder.

The ornaments on the head tube, the cable routing elements on the central tube and the dice shaped form at the rear brake attachment lead me to think it is Battaglin but not completely sure about it.

I also uploaded a new photo to my gallery of the bottle screw star shaped ornaments.

But I still cant find any clues based on the serial number.

Do you think this sounds reasonable?

WOW... Nice bike no matter the make! Possibly Eastern European?

Looks ready to ride and certainly would make for me a great winter weather project...

Serial number on the seat post lug has to be pretty unique. Mondia often did the serial on the left seat stay cap, and in a similar "font". Is the bottom bracket Swiss threaded (markings on the BB cups should tell that story)?

(The orange bike pictured is a late-70s Mondia, with non-windowed lugs; and before the time of "aero" brake cable routing through top tube.)

presence of EDCO headset would fit in with possible CH origin

forum had a recent frame ID thread with serial on seat lug which turned out to be a Mondia -

cycle also exhibited an EDCO headset

ID completed by none other than DCI Moss

Besides the unusual placement of the serial number on the seat lug, the other two details that stand out to me are the braze-on for the front (Huret?) derailleur and the screw on the downtube just below the shifters. (for some sort of integrated or aero shifter set?

here is an illustration for the Sachs/Huret braze-on front mech from the manufacturer's catalogue of 1985

unfortunately a part number for the braze-on is not given...

​​​​​​https://velo-pages.com/main.php?g2_v...serialNumber=3

the ALGI 5.0mm X .8 screw (think "Christophe toeclip bolt") in the downtube is there as a "placeholder" to close off the hole for the mount point of a set of topmount shifters

cycle's apparent date of circa 1984 puts it in that brief time period when such shift lever sets were a trend


-----

That looks like a square boss for a set of top-mount shifters; perhaps whoever equipped the bike only had a set of old-school band-clamp shifters on hand at the time. The remaining braze-ons give this bike such a "lean/clean" look otherwise, the band clamp is a bit of a sore thumb. Installing the right top-mount set for that boss would definitely do the overall appearance justice.

Wonder what potential ID information lurks on the steerer tube.

my guess is this is Swiss but: 26.6 seatpost would not be typical Aelle, a 26.8 seatpost would be more likely for Aelle but not in METRIC dimensions. If the ODs of the main tubes are even mms then the tubing is metric (but if fractional mms then perhaps not Swiss after all) and a properly fitting 26.6 could make it SL seat tube.
So what's the BB threading?
Are there 5 spiral ridges in the butt of the fork's steerer?
The brake bridge is a commonplace item not distinctive for Battaglin or any certain marque, but the pointed stay ends and fork blade ends sure look "Swiss" to me.

I think that's a SunTour Cyclone M-II front derailleur, with the "endless" band clamp removed. You can just make out the logotype on the outer plate.
And here are the SunTour shifters that go with it, the "Symmetric" ones that mount to the top tube with one screw, like the OP's frame has.

I have seen that paint scheme before

84 Pinarello, The 85 Montello had tt internal cable route

whoever selected the scheme for the subject machine may have been inspired by Alexi Grewal's olympic gold medal mount of the 1984 Los Angeles games...

Hey, thank you all for your comments :)

I recently disassembled the frame and started preparing it for a repaint.

The seat post is 26,4 size
BB is Britisch thread Suntour BC 1.37x24T, 68x118
Frame weight 2081g
Fork weight 653 g

I removed the paint from the fork and there is a matching serial number of the main frame and its labeled „Reynolds 531 Butted“ and number 152

It should be 100% Mondia and I recently recreated all the decals from the 1985-1989 models and can‘t wait to see how it will turn out

I will keep you posted with the final result!
