Joy,

I think I might be able to help you. I'm about 5'1", live in the south bay, and have an extra road bike. It's my 20 year old Bianchi with an 18" frame.

PM me for the details.

EDIT: Uh oh, never mind. Whenever I see South Bay, I think South San Francisco Bay Area. I'm such a NorCal-centric. Sorry 'bout that, and good luck on your search for a road bike.

PS Are there any used bikes on craigslist in your size?
