Mr. Tuffy Tire Liner 700x20
Made of durable, lightweight, biodegradable material, Mr. Tuffy tire liners allow you to ride flat-free by providing a protective barrier between your inner tube and road hazards such as glass, nails, thorns and other sharp objects.
- Fits 700c x 20-25 and 27" x 1" tires
- Advanced micro-shell technology features a hardened protective outer layer and an ultra-soft inner layer to cushion the tube
- Weighs less than liquid sealants or thorn-resistant tubes
- Easy to install--no gooey mess
- Contributes to a smooth, stable ride
- All Mr. Tuffy and Mr. Tuffy Ultra-Lite Tire Liners are now made with a new additive that causes them to biodegrade once disposed of in a landfill or composting facility after a long and useful life
