Is this frame dead or am I silly? - Bottom Bracket help

So I found a bike frame in good nic, or so I think?
The bike is an old ROC Record from Slovenia.
I'm having trouble sourcing the bottom bracket
There appears to be no threads in the frame - is this a thing? or is there a bottom bracket stuck in the frame making it dead?

Ive uploaded some photos
Any help would be appreciated

That looks like a Thompson bottom bracket. They had pressed-in cups.

might be -

It's definitely not a USA bottom bracket, actually the worst BB standard ever

That's probably ROG, not ROC. It's most probably been produced in former Yugoslavia. I have no idea about the BB standard, though.

Thompson bottom

Think you're right there, finding one of those to fix is going to be a big task

Is it standard BB dimensions just without the threads?

It's something like this

I think...

Bottom bracket Axle size is 175mm
The cup is 40mm

One of these adapter thingys will possibly work in that frame.
Google ”American to euro bb adapter”..

Might be easier to get a new frame though..

I love this forum, and this thread is a good example of one of the reasons why.

Never seen one of those before, very handy to know.

I don't think it'll fit unless I drill those 3 rods through the frame inside the BB
but still good to know

No you can just smash those bearing cups out.. they are just press fit..

Pls smash

Oops..😬

Just bang them out..

hi,

how di you solve this frame? Have you manage to fit in some new bracket. I have same frame and looking for solution.
