my bike is a 2007 khs flite 300. I know its entry level but I like it. its solid and still in really good shape with about 1000 miles on it as per the PO. the frame is double butted 7005 aluminum and carbon fork. I would really like to upgrade the wheelset to something a lot lighter and stronger and dont want to throw too much money at a bike that cost me 200 bucks. opinions? btw, i figure the frame was made in china or taiwan? does that even matter these days anyway? thanks all
