anyone recongnize this titanium frame?
 

he says its from a freind;) , why?

Looks kind of like Yetis... did they ever make a Ti frame?

Those are old Titan Halftrac frames; from about 1990-93. Nice riding frames, but old school geometry. 71/71 degree head and seat angles; best with a short rigid fork, or something in the 3" travel range. No rear disc mounts, obviously, and has a canti brake straddle cable hanger built in.

They take a pressed in sealed bearing bottom bracket (these look like they have the bearings, but you'd have to find some spindles. They take stright, non stepped spindles and use lockring collars outside the bearings to set the preload on the bearings. may be something very hard to find now. )

They also take a 1-1/4" headset; not as hard to find as the BB, but still not super easy to come by. The seatpost size was something like a 26.8mm or something, and needs a seatclamp collar. I don't recall what size for that, or for the front mech. The shift cables run on the downtube, and the rear brake cable is on the toptube - three pressed in cables guides are there, but they like to pop out.

Standard 135mm rear hub spacing, decent tire clearance. A fairly long wheelbase. Very comfy riding frames.

I had and rode one of these for about 6 years; a sweet bike. If you can get the parts you need, it'd make a sweet full rigid lightweight ride.

I'd pass, unless you are a dab hand bike mechanic, and enjoy tracking down old/obscure/harder to find parts.
