So i am a complete noob at this for starters, i recently got a used huffy road bike from craigslist. Its a huffy frame with shimano for everything else, both the front and rear wheels are bent, and the tire are gone.

Since i am still new at this i have no idea which wheels will fit, the rim measures 24 inches, i took it down to my local bike shop and the guy told me it was 26 1-3/8

I wanna pick up a used set of used wheels off ebay with tires, so do i look for the 26 1-3/8 or the 24 inch wheel, and this is probably stupid but will a 700c fit?
