Guide Review - Review of the Slime Flat Resistant Tubes
Slime self-sealing flat resisant tubes are regular butyl rubber tubes filled with "Slime" sealant, which is a bright green liquid with tiny fibers and rubber particles suspended it to to act as a clotting agent. During everyday use the sealant stays liquid inside your tube, evenly distributed around the inside as the wheel spins.
When a puncture occurs, the sealant seeps into any small holes, pushed there by the escaping air. The Slime sealant then quickly seals the hole, clogging it with the clotting agent to prevent further loss of pressure, even as you're riding. You often won't even know you had a flat.
If you ride in an area where the roads have with glass shards, wire, or small thorns these tubes are nice and will save you headaches with changing tires, walking alongside the road pushing your bike, etc.
Though it can be used to patch existing flats, Slime is not intended for use in tubes losing pressure from sidewall punctures, bead leaks, damaged rims or faulty valves. Not recommended for use in tubeless tires.
