Inner tubers are basically all the same. Just dont get some wierd off brand. Amd make sure ya get a metal valve stem. Like most everything else if ya aren't sure what brand ya like, dont get them most expensive or the cheapest. Middle of the road will suit ya fine. I use parts unlimited tubes and haven't even bothered to see who makes them. They have done me and my customers fine.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
