Standard Butyl Inner Tube

They're inner tubes, The End™. They're simple old-school technology and constructed of tried-and-true materials; they work well on my vintage road bike. If you're riding tubes on vintage rims, and you're more than 5 pounds overweight yourself, these are the way to go.

The tubes are great and now i have a few extra on deck. Thanks again
Great price . It was worth buying a few more and free shipping

I have always rode on Continentals while my friends ride Vittoria that seem to roll a bit faster. Only mounted a pair 2 weeks ago but so far I find the Corsa Pro's and tube combo to be a smoother ride and the comments from fellow riders of how much stronger my riding is speaks to the Vittoria set up. How ever I have not flatted in a few years so a piece of glass in the middle of my ride yesterday was disappointing and thus a 4 star rating. Time and many more miles will tell how the Vittoria set up works overall for me.

I could have sworn I was buying Schraders.

I bought two tubes, one was good and the other came with a hole in it.
