Reifeninnenliner

Reifeninnenliner, also known as tire liners or tire inserts, are protective layers installed inside a bicycle tire. Their primary purpose is to provide an additional barrier against punctures caused by sharp objects on the road or trail. These objects, such as thorns, glass shards, or small stones, can penetrate the tire casing and inner tube, leading to a flat tire.

Tire liners are typically made from durable materials like polyurethane, aramid fibers, or a combination of plastics. They are usually inserted between the tire and the inner tube during installation. The liner absorbs the impact of sharp objects, preventing them from reaching and puncturing the inner tube. Some liners are designed to cover the entire circumference of the tire, while others are narrower and focus on the tread area.

The effectiveness of tire liners can vary depending on the material, thickness, and quality of the product. While they offer enhanced puncture protection, they can also add weight to the wheel and may slightly affect the tire's rolling resistance and ride feel. Despite these potential drawbacks,reifeninnenliner are a popular choice for cyclists who ride in areas with a high risk of punctures or who seek to minimize the frequency of flat tires. They are a relatively inexpensive and easy-to-install accessory that can significantly improve the reliability of a bicycle.
