Tire inserts for bicycle tires
Anti-puncture inserts, anti-impact inserts, or just inserts for bicycle tires have become an indispensable element of bicycle equipment for people practicing extreme types of mountain biking. Anti-puncture inserts are made of dense foam and their main application is for tubeless tires. They are mounted on the rim in place of the inner tube, and the whole thing is sealed with sealing fluid/sealant. These inserts are designed to increase protection against tire damage, protect the rim, and additionally stiffen the tires and dampen vibrations, which improves driving comfort.
Tire inserts
they are especially useful for cyclists who ride aggressively in difficult terrain where there is a high risk of tire/rim damage. Anti-puncture inserts differ in their structure, they may have simple or complex shapes, but they are usually made of a similar material, and the differences lie in its density, which translates into their hardness.
Anti-puncture inserts are most often used in mountain bikes (mainly Enduro, All Mountain, Downhill), but in recent seasons they have also become more popular among gravel and road cyclists. The best brands in one place: Flat Out, Cusch Core, Tannus, Vittoria, Dark.Bike.
