Long story somewhat short....My brother remodels foreclosed houses and resells. He found this frame in a basement, thought I could use it. The frame had been stripped down to bare aluminum, no decals. I have no ide what manufacturer it is, but after looking it over it was decent, light, and usuable. After some measuring I figured out the frame size would fit me, and it was a frame for 29" wheels. I cleaned it up, gave it a $10 paint job to avoid oxidizing, and found enough spare parts to end up with some sort of 26lb unknown rigid/beater/29er. Took it for a spin this morning (froze my arse off) and it rides really well. I am impressed with the handling, and may even go so far as to upgrade the front end with a suspension fork, Rockshox Recon Silver Solo air or similar. cheers!
