Over the following weeks, I pre-filled my tubes with Slime, and I didn’t experience a single flat. It’s nice knowing I’ve got two years of protection without constantly worrying about punctures.

It’s also environmentally friendly, non-toxic, and water-soluble, so I don’t have to stress about harmful chemicals.
