X-Grip durable foam insert designed for 18" tubeless tires. Improves control, absorbs impacts, and supports ultra-low pressure riding. Mousse Application Guide The X-Grip V2 Blow Mousse is specifically engineered for 18" tubeless system tires and is 100% made in Austria. Designed to support extreme off-road conditions, it provides critical protection when tire pressure drops-or even disappears entirely. Whether you&';re navigating rock gardens, tree roots, or hard enduro terrain, this mousse acts as your backup plan by protecting both the rim and high-pressure tube inside your tubeless setup. Its fit and volume are fine-tuned for better sidewall support and control, especially at ultra-low pressures. Even when running 0.0 bar, the mousse keeps the tire stable and rideable. The material&&';;s built-in damping effect helps absorb hits, resulting in smoother handling and increased traction. It also minimizes the risk of pressure loss and internal damage to the tire, making it a reliable solution for finishing your ride or race without interruption. For best results and longer lifespan, maintain a minimum of 0.15 bar air pressure during use.
