One of the most common questions I get about bikepacking and endurance races like the Arizona Trail 300 is how you can carry everything you need. The answer, which I've come to after generous input from others and lots of trial and error, is a combination of lightweight gear, packs that fit your bike, and miserly packing. The products below aren't everything that I use, nor will they work for everyone. I know guys that run dramatically different setups than mine, and every race calls for a different set of gear. But I've found the following items reliable and indispensible over lots of trips into the backcountry.

Depending on how rough a course is, I choose between a full-suspension 29er like this Specialized Epic 29er or my tried-and-true Moots Mooto X YBB. Stiff wheels are a must for handling the big loads (I love the Easton EC90 XC 29"), and thru-axles on front and back help, too. Fully loaded for the AZT, my rig weighs 34 pounds, including 5,000 calories and one full water bottle.
