After 43 years the hassle of sew-up tires became too much. My friend at Reset Bike Shop in Portage , MI convinced me to let him lace clincher rims & tires to my Campagnolo hubs.
The new clincher tires can hold 125 psi, so the low rolling resistance of the old-school sew-ups won't be missed entirely. Now my wife can ride her 45 year-old Schwinn and I can ride my newer (43 year-old) Legnano in Detroit's "Slow Roll." I believe I'll leave the music to the other rollers.
