The big thing about "Sew-ups" I found was that that corner like glue. The better rounded tire will hold better as you lay it on its side. A clincher besides being quite a bit heavier just doesn't hold as well in a corner. Take the same bike, switch between wheels, and you will notice a huge difference. The big advantage to clinchers comes in the real world where you don't have a support vehicle behind you. Tubulars are glued on for a reason. So they don't come off. Now think of the fun when you want them to come off. Remember that glue takes time. You will probably just take your spare and pop it on. So the rest of your ride is spent on what is essentially an unsafe wheel. You take out the Ferrari and you will have to deal with the Ferrari maintenance. As much as I loved the feel of the tubulars, the heartbreak of letting the air out of a Criterium Seta is just too real. Count me as a clincher fan.
