IF this frame fits you, and IF I were you, I'd find a bike co-op, take it there, and build it up as a cheap single speed mountain bike. Do some research online first (the bike originally came with 26" wheels), and ask for help at the co-op.

Personally I wouldn't put much money into a build like this. I would use all used parts from a co-op.

You cannot afford to build/convert this bike with new parts, nor is it worth it.
