I would spread some good rep for Unrealcycles.com. Its a great site to get parts, though it is phone order only, hes a really nice guy and has helped me out with alot of stuff.
However he only carrys stuff for bikes, he has a awesome Rim and tire selection. He also has tons of sweetass pedals and seat posts.
So if your building a muni or street 24"-26" i highly recomend getting your stuff from him.
