Is there such a wheel that is as thin as a 700c, but has a larger diameter? The fixie I am building has quite a large chain stay, and appears to me that I could fit a 750c wheel in the back if there is such a thing. I know there is 650c and 700c, but I do not know if there is anything larger than a 700c. Thanks!

P.S. Here are a few pictures of my build :
