Odyssey OPTIS Tubeless Tire Insert

The OPTIS is designed for standard tubeless systems using Presta valves. As long as your rim thickness at the valve hole does not exceed 18mm, it should be compatible with most modern tubeless-ready mountain and gravel wheels.

The insert physically presses the tire bead against the rim wall. This creates a more secure seal that prevents air from escaping during hard cornering or high-impact maneuvers, even when you are running lower tire pressures.

Not at all. The installation process is very similar to fitting a standard inner tube. Because the insert helps hold the tire bead in place, many riders actually find it makes seating the tire easier than a standard tubeless setup.

Yes, it provides temporary run-flat capability. In the event of a puncture or sidewall tear, the insert acts as a buffer between your rim and the ground, allowing you to ride slowly to a safe spot without damaging your expensive carbon or alloy rims.

The OPTIS is engineered to be exceptionally lightweight compared to many other foam inserts on the market. While it does add a small amount of rotational weight, the performance benefits of increased grip and rim protection usually outweigh the minimal mass.

You will likely notice improved stability and better rolling efficiency over rough, technical terrain. By allowing you to safely run lower tire pressures, the insert helps the tire conform to the ground better, providing more traction and a smoother ride quality.
