so I'm taking in my Fuji Royale I got for free for upgrades to a shop just wondering if its worth modern upgrades like 700c wheels crank and cog swap for hill adaptation. I'm going to be needing the bike for long distance commuting in below zero temperatures to school and work through the downtown city traffic so I need it as comfortable and adaptable as possible as well as quick and efficient while using as less effort as possible so you know smooth ill also be climbing hills. So are these upgrades worth it for this 70-80s bike? The most I can afford to put in it is 100 for now. the gearing I might be able to get used but the wheels might be new. I want to stick with this bike until I can afford a better one. I just don't want the shop to lie to me in order to get me to buy parts, no offense. So is it worth it? Thank You very much.
