With Addix, Schwalbe offers significantly improved solutions, especially regarding tire lifespan, and sets a performance level for all MTB disciplines with their diverse requirements, not just in competitive use. For the Addix compound, Schwalbe employs a state-of-the-art and highly precise mixing technology that is not used elsewhere in the bicycle tire industry. Two different rubber mixtures provide better performance. Puncture protection level 4. A double layer of nylon fabric ensures solid protection, especially for lightweight and sporty tires. One of the most effective inventions that Schwalbe has developed for bikes. A tire only becomes about 40-50 g heavier with the SnakeSkin fabric. This provides excellent protection against contact with sharp edges, which can quickly slice open the sidewall of lightweight competition tires. For fast e-bikes, a special approval of the tires is necessary. Tires with the Europe-wide valid ECE-R75 approval are the simplest solution here.
