I finished this frame a month ago but will not be able to build it up for a couple of months when I get back to the states. Thought I'd show the pictures of it anyway. I can get a 2.3 tire in the back and the chain stay length is less than 15". I had to move the seat post to get the tire in that tight. I might be able to squeeze another half inch out of it next time. The frame is powder coated to look like a shop tool. Heavy fillets where used for strength but the frame is still only 4.75 pounds.
