I am trying to get a bike to ride for fitness and to work. 9 miles one way. I was offered a 2002 cannondale m300 for $150.00. I know very littlel about bikes but i am learning pretty fast. My question is if i buy a bike this old will i be able to get parts for it? and should i take it to a bike shop to get it checked out first or is this something i could check myself. thanks much.
