Getting a flat is never fun, and while there are plenty of remedies, Kenda Tube Protectors might be another to consider. This tire liner is made of durable yet lightweight polyurethane that is meant to be inserted between the bike tire and the tubes, and thus provides an extra protective layer between road hazards and the inner tube. This can help protect from thorns, glass and other objects that could leave you walking home.
Unlike rubber this material is actually lighter, thus adding little extra weight to the bicycle and is reportedly 97 percent effective in preventing flats from road debris.
