No gravel near me so I have to travel for hours and sometimes days to get to it. Love it and the quiet, no traffic riding. Didn't justify a new purchase because of gravel, as my Kona Rove Ti is my everything bike. Sorry that you are feeing that way, but I love it. Maybe go for a light front suspension like the Lauf or shorten the rides. You might also consider why you are getting so worn out. Maybe extra inflammation from a medium to high carb diet (research lectins, ibuprofen, and other causes)? Just a thought.
Either way, you are still riding and enjoying! Go where you feel best and have fun.
