I know some folks worship Sheldon Brown, but I also know I have done decades of riding and changed hundreds of flat—this includes a stint as tire repairer on a cross-country tour with more than two dozen riders, plus decades of urban commuting in terrible conditions—and I have Never faced a stuck nut.
