The difference between the 9 speed Quick and the 11 speed Topstone is real and I really want to stick with the 11 spd. Right now I have a lot going on in my head about what I should or can do and still be happy with the results. Be safe and I will try to decide what I am going to do in the near future. I have also played with the idea of converting the 9 spd Quick to a 11 spd bike so again, I have too much going on in my head.
