What is an average cross country ride? I had a 38t chainring on a 1X Mtb but after 2 rides i gave in/ up and promptly ordered a 32t which was much more accomadating for the type of terrain that is in my "backyard". I was just trying to be tough when i put the 38t on, thinking a 32t was for wimps . Live and learn from your mistakes, both big and small.So a 36 tooth up front then for average cross country rides
