this is what Scott Fyrry had to say about this frame:
Yeah if it is from 1986, then most likely it is a Profile frame. There were only a couple of full sized Cro-Mo frames out there that in '86 that were made for a couple factory riders like Eddie Sigmond and Todd Mitchell. It wasn't until about 1987 that we started making a full line Cro-Mo frames. Plus, if this is a Jr sized frame, we would have used a small diameter bottom bracket, rather than the full sized seen in the picture. Hope this helps.
I think it was a Profile frame and someone took and welded on the struts, this was not done by Titan when I Dad and I owned it. Profile never made frames for us. This frame could even be older than '86, it could be from 1985. It is not a real Titan in the sense that it was not built in Eugene, OR.
