Tubfritt

Tubfritt is a brand of puncture protection strips for bicycle tires. These strips are inserted between the inner tube and the tire itself, providing an additional layer of defense against sharp objects that could otherwise cause a flat tire. The concept behind tubfritt is to absorb or deflect punctures before they reach the inner tube.

The product is typically made from a flexible but durable material designed to withstand the forces encountered during cycling. When a sharp object like a thorn or a piece of glass penetrates the tire tread, the tubfritt strip aims to either push the object away or prevent it from piercing the inner tube. This can significantly reduce the frequency of flats, especially for riders who frequently encounter rough terrain or debris on their routes.

Installation involves deflating the tire, removing the tire and inner tube, placing the tubfritt strip onto the rim where the inner tube would normally sit, and then reinstalling the inner tube and tire. While it adds a layer of protection, it also adds a small amount of weight and can slightly affect the feel of the ride. Users often report a decrease in the number of punctures experienced after fitting tubfritt. The effectiveness can vary depending on the type of puncture and the specific conditions.
