Upgrade your tubeless-ready mountain bike or e-bike wheels with the Operation Overlord Anaconda 3.0 Barbieri anti-puncture inserts. Engineered from ultra-durable, high-resilience foam, these inserts provide a robust safety barrier between your rim and tire, significantly reducing the risk of bead failure, rim damage, and dangerous pressure loss from punctures. Ideal for technical descents and long-distance rides, the Anaconda 3.0 inserts allow you to continue riding safely—even with a flat tire—by maintaining tire shape and preventing sudden pressure drops. Ride with lower pressures for enhanced traction and control without compromising safety.
