The name says it all. My fifth ride since the weather started to get better and my back just can’t stop hurting. That wasn’t an issue last year though. I think that I just have to ride it off, get used to the bike again after the winter. What is your opinion? What are the factors that can contribute to my problem? I have changed my flat bar to raiser 2” and an Eston 50 stem>>100mm 0 degrees.
