I spent two years with back issues related to a disc, and the best medicine I found was a week riding an XTZ off road in Morocco. Seriously, my back was better at the end of that week than it had been at any time in the previous two years. That was back in May of this year. I came home, bought an XTZ of my own and have stayed more or less pain free ever since. The more I ride the XT, the better it is.

Happily, it's a fun bike to ride too. I hope yours does for your back what mine has for mine. Welcome to the XT club.
