Hello, I'm selling my Giant Defy 5 (size M) for $200. The bike requires some maintenance ($75 at the Stanford bike shop) but as it is now is functional (I use it everyday for my commute). I'm selling only because I'm leaving the country. I bought it 4 years ago for $900. I can show you the bike any day of the next week on campus, but I need the bike until Monday (6/29). Please, reply to oliveirajhm@gmail.com or txt me at 415 940 2483. I can give you a helmet and a u-look.
Thanks,
Jose
