Uploaded pics of the bottom of the steerer tube. Hope you can see clearly.

Wrong tube.

Your pics are of the head tube (part of bike frame), while @T-Mar was referencing the steerer tube, which is part of the fork. Helical ridges will be on the bottom of the tube only if there.

Sorry about that. My technical English needs improvement. It's not so easy to translate everything. I've uploaded pics of the fork as well now.

You are doing a great job with your English.

Wish my Spanish and German were as proficient as your English.

btw Interesting bike you have there. I've owned two Tommasini Racing framesets.

Neither of mine had a panto'd fork. In fact, both of mine looked quite similar to yours.

Fun thread.

Do you have pictures, gomango?
So i can get inspiration for the rebuild...

T-Mar

Here's a picture of what the helical ridges look like inside the bottom of the fork's steerer tube. Alternately, since you've removed the fork, you can check for Columbus' dove logo on the outside of the steerer tube. If neither are present, then either the fork is a replacement or it's a Columbus tretubi frame (i.e main tubes are Columbus SL, while forks and stays are lesser grade material). As previously noted by myself and confirmed by gomango, Tommasini did market forks without embossing.

Now it's clear to me. Thx T-Mar.
New pics taken and uploaded.
But no helical ridges or Columbus marking. Only a ' T ' on the steerer tube.

' T ' for Tommasini or too bad.

I would trust the experts above on a fork not being needed. For future needs I often end up on ebay where you can find parts like this Tommasini fork in the UK:https://www.ebay.com/itm/Tommasini-C...frcectupt=true
Looking forward to seeing you build completed.

Honestly, the fork works with the way the bike looks. I would spend the money on getting decent components as they need replacement, and giving the whole frame and fork a nice cleaning. Great bike as is. Especially if the fork pitting and rust is just surface.

Just enjoy the ride!

+1, given the lack of embossing on the frame itself, I'd leave the current fork. It appears to be OEM and while later Tommasini forks are readily available, a period correct fork with the chainring embossing will be harder to find and getting one with the minimum required length is going to be even harder.

It's definitely not a Columbus SL fork. I haven't seen any Tommasini from this era below Columbus SL tretubi level, so that's what I would assume it to be. However, to confirm this and rule out Aelle, you should check the seat post size, which should be stamped on it. That will give a good indication of the tubeset used for the main triangle.

Just checked the seat post. It says 3 ttt and 27.2. Now i have one problem left. It is really stuck in there. Any tips on how to get it out? I've sprayed it with wd40 several times, tried to move it with a wrench but no luck.

PB Blaster and time.

Not available in Belgium. But i get the picture.

I’ll check my cloud account, but likely no.

My Flickr will no longer be updated for bikes. I used it for show and tell purposes, but I’m more interested in online privacy nowadays.

If it were me, I would just clean up the frameset, collect the needed bits and build it. If you are dropping money into it as a rider, you should be fine.

Agreed with T-mar and the other Learned Elders, clean up that fork, as well as the frame, and put it together as a rider. You can round up the necessary components of your choice and budget level to complete the bike, and you'll have a nice riding, enjoyable bicycle for yourself.

This can be simple with a penetrant or get out of hand quickly. Google "stuck seat post" and lots will come up, start with Park Tool, Sheldon Brown and/or You Tube.

T-Mar

A 27.2mm seat post is indicative of a tretubi frameset where the main tubes are Columbus SL, with the stays and fork baldes being a lower grade steel, typically Columbus Aelle or Falck.

There are literally dozens of methods that can be used in an attempt to extract a stuck seat post. Here's a primer from the late, great Sheldon Brown. https://sheldonbrown.com/stuck-seatposts.html

So, the frame is stripped from all parts, except the seat stem. I'm going to give up trying to save it and just cut it and drill it out.
Since the frame seems to be repainted allready, i've decided to sandblast and powdercoat it. Any ideas of a period correct colour scheme?
And where to get new decals?
Thanks for all the help.
