Titanium frame identification please
 

Hi, I bought this frame from a flee market. Doesn't have any marks on it, I am pretty certain it is titanium because of the small diameter tubing, non-magnetic, light and no paint.
If you could please help identify the maker and/or model, if you've seen something like it before or any comments would be welcomed.

The bottom bracket is a weird thing: although the frame is old, the BB is custom built to take in sealed bearings and an axle goes through them (it seems so ahead of it's time). I have a problem with the bearings because I can't find the size that fit.
I wish to build a fixed-gear out of it. Hopefully if I identify the maker, I may find the correct size bearings.

Thank you for your opinions.

Are those 2 grub screws in the BB shell? If so, may be Merlin (grease guard BB). And looks like an MTB frame.

Interesting frame. Those dropouts were unexpected, especially with the dual eyelets. What is the rear spacing?

Are you planning on trying your luck with a magic gear, white industries eno hub, or frame modification (EBB or dropout replacement) to make it a fixed gear?

Doesn't look like a production frame. Might be a one-off. Pretty unusual design.

I remember seeing these in the mid 90's but I can't remember the name. Russian-made, "budget" Ti. Totally serviceable high-performance MTB frames, just not as pretty or sophisticated as the US made stuff of the time.

FTW may be able to give you some info on that back-end design...

Lord, I hope not.

I've seen this bike somewhere.....
.

Sibex?

Thank you for your input.
Yes, it is a 26" wheels frame.
I plan to use a chain tensioner to use it as a singlespeed.
I did look over the internet about Sibex, did not find a manufacturer site. I did find though a bunch of pictures with broken Sibex TI forms, which gave me something to worry about now :)
Now I am looking for the right size press-fitted bearings, which turn out to be hard to find in that dimension.

Any comments are still welcomed. Thanks.

I knew I'd be able to remember the name: Titan.

Thank you tashi.
From the links you posted I am inclined to believe that the frame was made by the US based Titan company, the one that manufactured bmx-es. The frame has indeed a bmx-like design.
What would the connection be to the chinese company titanproduct.com?
Anyway your post solved my concerns about the headtube which I am now conviced it is 1.1/4". I am going to use reducers to 1.1/8" as the ChrisKing Devolution is to expensive...

This. I remember it being Russian.
