Boom, the double aero. Current state of mi Dr. Leaf's Joyride.

To all the gram-countin' pussies, this is New York Fuckin' City, you need the Beefy shit. It's only a coupla extra ounces. Plus, once you get these fuckers going, you're riding a plane on cruise control, they generate some serious forward motion.
I gotta have the brake, cuz these guys don't skid so well. They're a little more flexi than your regular wheel and you will get weird wobbly bouncing action. Plus they are weighted and you are also going much faster than average.
