As any listener to the Pulpmx Show knows one of the things that drive me nuts is the mechanics of the sport getting more and more loaded down with crap that doesn't matter. I was a mechanic for 11 years for various teams and have seen this evolution just get weirder and weirder. There's nothing you can do to a bike in a supercross race that you need a backpack full of tools and parts for. Bring the basics in a small simple fanny pack and you're good.
