It's a Giant Stonebreaker from early 90s I think. I want to tour in Europe on it.
I put new KMC chain and a new shimano singapoure 7 speed freewheel (12-28)
Front chainrings are triple with 28 the lowest and 43 the highest. Would this be enough to bike up the mountains?
It weights 40 lbs, but the read rack is heavy steel one. Shifters and rear der. are made by suntour. Wheel are femco 26 inch.
Would slick tires make it easier to pedal?
Any opinions and suggestions would be nicely appreciated.
