Tannus Fusion is the world’s first modular tubeless tyre insert system. Composed of two interlocking components, it lets riders customize the exact level of tyre protection they need. Each section of the Fusion insert can also be used on its own, making it suitable for everything from road rides to rugged trails.
Riders choose Fusion because they push their limits and demand reliable protection. While you may notice a slight increase in tyre weight, the added stability provides the confidence to tackle rough descents with ease.
