I just got word my bike is finally in and will be picking it up next weekend. I dont have anytime between now and that date to go try on some gear, but I want to order some in asap so it will arrive hopefully by next weekend. I am looking for a helmet, jacket, and gloves. Is there any tricks to determine what size I need without actually trying anything on? Im 6ft 2in, 160ish lbs (been a few since I weighed myself). Any measurements that I can use to get the right size ordered in?
