I did a little check on what the powder in/on bike inner tubes was, and found it was talcum powder (proven to cause cancer) .. Shame cause I was considering reusing the rubber to wrap my bike where I place my U-lock. Why do you want to buy a product that knowingly contains carcinogens? (parallels to cigarettes)
Are there any tubes sold without it?
And in the "Slime" brand tubes that seal themselves after flats, what is the green slime sealant made of? curious
