Recently I got a second hand road bike and I’m now able to experience the joy of gears on a bike that I’ve never been able to before. Yesterday I went to go lock my bike and busted my rear tire going up a curb (it was my dumbass fault). I stumbled upon a gentleman that was gracious enough to help me install my spare inner tube in so I could continue my day and get home safely, but I noticed ever since we put my wheel back on, my bike has stayed in 7th gear even if I use my shifter. There was a cable that we had to move quite a bit and I try to make sure that was properly connected, but I’m still having this issue.
