THREE Mr.Tuffy Gold Bicycle Tire Liners 700Cx32-41 , 29 x 1.5-2.0
Tire Liners
Tire Liners (aka Tube Protectors) shield against punctures from thorns, glass, and road debris - the nemesis of every bicyclist.
Strong Stuff! - Made of durable, lightweight urethane, Mr. Tuffy provides a protective layer between the outer tire and inner tube. Urethane has a property which makes it very elastic. When a thorn or piece of glass attempts to penetrate the Mr. Tuffy liner it comes up against a surface that is both hard and elastic. The object pushes against the surface which gives way while resisting initial penetration.
2 Layers Tuff - With the introduction of the dual layer Mr. Tuffy over 10 years ago, we made our liners even more impenetrable by fusing a hardened strip to the original pliant, lightweight urethane strip. This Micro-Shell layer provides an even better shield against punctures.
