Odyssey OPTIS Tubeless Tire Insert

Unlike foam inserts that rely on density to absorb impact, the OPTIS system uses air pressure. This allows you to fine-tune the feel of the insert independently of your tire pressure, offering a more tunable ride quality and a lighter overall weight.

The OPTIS is designed for 27.5-inch wheels and is compatible with standard tubeless-ready setups. Because it uses a Presta valve, ensure your rim profile is compatible with standard tubeless valves before installation.

Yes. The insert helps push the tire beads outward against the rim walls, which makes seating the tire significantly easier, especially if you are struggling to get the bead to pop into place with a standard floor pump.

By locking the tire bead securely against the rim, the insert creates a more stable interface. This prevents the tire sidewall from folding or shifting during hard cornering, which is the primary cause of air loss or 'burping' in tubeless systems.

The insert provides temporary run-flat capabilities. If you puncture your tire, the inflated insert acts as a cushion between the rim and the ground, allowing you to ride slowly to a safe spot without damaging your rim.
