What's the big fuss about? Back in the day I was a poor student and rode sewups whether I was racing, touring or commuting. Nobody I knew at the time would have ever dreamed of throwing sewups away simply because they flatted. When touring, I often repaired flats sitting on the side of the road. It may seem a difficult job the first time you do it, but after that it becomes routine. The only really hard parts of fixing sewup flats are: 1) locating the puncture to determine where to cut; and, 2) pulling the rim tape off. Number 1 just takes a little patience. Number 2 just takes some careful work with razor and pliers.
