Good article Muirenn, thank you, I need this info for sure! I am actually in the midst of looking on eBay for a used bike ( I am in the UK for the rest of the summer) and am going to go to several bike shops to look at bikes and find a shop that I like, as when I finally find a good used bike (that I like and that won't break my bank account) I will bring it in for a fitting/service, especially after all this going on with my neck.
I never really thought about how my body and bike need to work together before this, just kind of thought, ok, get on the bike and pedal, I've been doing this since I was a kid, I know how to ride a bike for goodness sake! Now I do know that I need to pay attention to all of this or my body will let me know in no uncertain terms that it is not happy.
