thank you guys for your help
1) sure i will have to put some new tires and bring one with me in case of, but im not sure if i can find any one of this brands you are talking about
2) my friend owns a bike shop so he is going to check the bike for me and change the seat to "selle italia "
3) im really considering upgrading my handlebars or adding grips, but if i can't find one i will have to stick with what i have.
4) i bought a used " thule pack ' 'n pedal tour rack" as for the bags i bought some asian brand bags, for 30 dollar brand new, they look good though.
5) the bike is used but in a good condition (200 dollar), i live in Tunisia, we have 3 good bike shops here they have awesome mountain bikes and road bikes but no touring bikes, so it's impossible to have the bike checked by a cannondale dealer.
