Giant Touring Bike - 1+ year old: $300 obo

I just got a road bike and am looking to get rid of my old bike. I bought it brand new in July 2010 and actually rode it through parts of China and brought it back. I used the bike all of last year and it is in solid shape and great for getting to and from class. The discs brake are real high quality, and if you are ever planning on taking the bike for a longer ride it is good for that. This is good from someone around 5'10-6'+ but my friend who is 5'8 felt fine riding it. It could definitely use a tune up and price is negotiable.
