What's there to get excited about a Schrader valve bicycle tube? Been fixing flats since I was a little kid in the 50's. Ran a bike shop during the 1970's and I've been using Presta valve tubes almost exclusively since 1973. I'm overhauling a friend's classic 1970's. A LBS sold me a pair of Specialized 700cx20-28 Schrader valve tubes. Out of the box they look better than any tubes I've ever seen. They have threaded metal valve stems with lock nuts and a smooth rubber surface that easily slides into the tire. Best thing is that they fit just right and don't bunch up from being oversized. Just bought two more so he'll have some spares.
