I'm looking to upgrade my Trek Navigator and I'm just wondering what you would all do with a stock bike knowing the following:
1. I'm 33 yrs old 155lbs 6'0"
2. I ride 95% of my time on a dedicated paved path (hilly but paved)
I am thinking about picking up new tires to try and gain some speed since mine are kind of wide. Does anyone have any specific tire suggestions that would fit my needs? I just feel slow and heavy on my bike right now.
What about other things that are good upgrades for this bike in my situation?
