This bundle includes two 27.5\" Optis Tubeless Tire Inserts, each equipped with a durable Presta valve and engineered for superior tubeless performance. Enhance your bikes handling and reduce rolling resistance with these innovative inserts, crafted from premium Nylon and Thermoplastic Polyurethane (TPU) for maximum durability and flexibility. The Optis system transforms your tire into a dual-chamber setup, allowing you to fine-tune tire grip and internal support independently, thanks to its unique dual-valve technology. This tunability enables lower tire pressures for increased traction and better shock absorption without sacrificing rim protection. Designed to fit rims with a maximum thickness of 18mm, each insert cinches securely against the tire bead, creating a bead lock that prevents burping, minimizes impact damage, and offers limited run-flat protection in puncture scenarios. Its lightweight design adds less than 90 grams per wheel, making it ideal for aggressive riding where every gram counts. The aluminum valve is removable for easy maintenance and durable performance.
