Editor's Pick: If you get a small nail in your tire mid-ride, the sealant inside this self-sealing inner tube plugs the small puncture so air won't leak out all at once — enough to get you home and deal with it later. The rubber body is made thick and sturdy, great for daily commutes or weekend mountain rides. The Schrader valve makes inflation easy — just clamp on a standard pump, and swapping it out at home is a breeze.
