Yea, People are out there on anything and everything. I’ve rode a 26er full sus converted single speed, 29ers 27.5 plus. You see fattys and skinnys alike. I think its only were u get into some of the big races that people will be more dialed into a specific category. I would most likely say 29er and 27.5 sizing and full sus and hard tail both. A lot is personal preference.
