I’m a fit 52 old on a 2007 3×9 26” Ibis Mojo planning to bikepack the Colorado Trail in July. The drivetrain has considerable wear, and probably needs to be replaced. Do I just stick with it or move to a more modern setup? I’m considering moving to 1X11, 30t front, 11-46 back. I know and don’t have issue with 50% HAB on this trail.

Any thoughts from this group?
