Fuji Feather

Picked this up in Jamaica Plain last February, I love it but I'm still not sure if it is a real quality ride, I kinda let it's looks sell me, it was certainly a better ride than the antiquated 10 speed schwinn I was sporting(still close to my heart wherever you are). I'm trying to learn about bikes so I can work on it myself. Soon It'll turn fixed and lose the rear breaks. I'm also looking to upgrade parts, but I'm not looking to do anything too drastic and waste money while everything is relatively new, plus I still have little knowledge of the subject.
