Slime Smart Tube with Sealant - 20 x 1.5-2.125"

Self-healing inner tube, filled with Slime sealant, that prevents punctures by sealing them, even while you ride.

When a puncture occurs, the escaping air pressure forces the liquid into the hole. Sealing agents inside the slime intertwine and clot to create a permanent, flexible and long lasting plug. So you can seal damages in the tread area up to 3 mm size. The tube installs like any other inner tube.

The slime tire sealant was developed after the Fibro-Seal technology. Thereby a mix of environmentally friendly fibers, binders, polymers and proprietary congealing agents are used. The liquid carrier substance collects itself automatically through the puncture area and seals it permanently with a flexible plug.
