Tubeless inserts were once used to prevent punctures from snakebites and to keep you out of the tech zone. Later, it was thought that inserts could protect your expensive rims. However, tubeless inserts only show their full potential at evolution stage 3: higher damping of up to 55%, better traction of up to 60%, lower rolling resistance of up to 9%, and optimized airflow and sealant flow. The Diamana tubeless inserts are also easy to install and self-centering, made from closed-cell EVA, ammonia-resistant, and offer an optimal weight-to-performance ratio. They provide efficient protection against snakebites and burping, stabilize the tire, and prevent the insert from rolling during braking or in the air. Tubolight Diamana HD is suitable for 2.3-2.6 inch tires, and XHD for 2.5-3.0 inch tires.
