I would take the advice the others are giving and ride until the bike breaks or you are ready to move up to something different. I purchased a Specialized Hardrock HT about 15 years ago (not knowing what I was getting into at the time) and just recently upgraded to another bike – Trek 4 Series. I rode the Specialized for a long time and it is still ride ready; however, I upgraded because of the age of my bike and some of the wear and tear on the bike. Stay safe riding and enjoy the trails.
