Step up your puncture protection with Tire Liners.

These re-usable polyurethane strips form a protective barrier along the inside of your tire, increasing protection against inner tube punctures caused by sharp objects like thorns and broken glass.

the liners are lighter than self-sealing and thorn resistant inner tubes, effective against a wider variety of road hazards, and they're easy to install -- no gooey mess. Sold in pairs (enough for one bicycle).
