Meanwhile, Dave’s day was turning into a series of unfortunate events. Besides getting lost, he’d crashed on a high-speed lakebed. He remounted and soldiered on, only to have his countershaft sprocket come loose and throw his drivechain. “It shattered into about 10 pieces,” Dave said later. “I watched it fly off.” The chain incident happened about a mile away from the pit and Dave was bound by the rules to push the bike to the pit.
