Well priced, good quality tubes for smaller tire sizes. I ran these in 2.5 and 2.4 inch tires and pinch flatted fairly easily. They were quite stretched to fill these tire sizes. It's well worth mentioning that the tires I was running were pathetic and had ultra thin sidewalls so it may not have been a fault of the tubes at all. The tubes have excellent long valve stems which extend nicely through deep rims. They are also light and compact so its easy to carry one as a spare in a camelback.

Feels like a decent tube but I haven't had anything happen to them.
