One of the best American trial riders ever, Aaron holds a record 10 AMA National Trials championships. In 2004 he tried EnduroCross for fun, loved it and kept working on speed until he became a title threat. In 2006, he retired from trials competition to focus on endurocross, where he's had two career wins and was Taddy Blazusiak's toughest competitor before a shoulder injury in April 2012 hampered his year. He hasn't cracked the top five in points since 2011. A sharp businessman and promoter of trials, Aaron runs trials demos for Red Bull and the military. Aaron has switched bike brands for 2015 and is now on Gas Gas.
