Super lightweight without the fragility of latex

I love these tubes. They are incredibly light weight and hold up much better than the latex tubes I've tried with similar weight.

These obviously aren't for everyday riding. The tubes are very thin so you have to be very careful when installing them. They're much more susceptible to pinch flats so I wouldn't recommend them for rough roads, and even on smooth roads you need to make sure your tires are properly inflated.

Light but unreliable

On several occasions, the valve CORE unscrewed with obvious loss of all air pressurewhen I was attempting to merely unscrew the valve tip. I've never

had this happen with any other tube.

Use if you dont mind losing your race entry fee

Most unreliable race tube I have ever used. Double flatted multiple times using different wheel sets. Buy a real tube and give yourself some confidence.
