Odyssey OPTIS Tubeless Tyre Insert

OPTIS (Odyssey Pneumatic Tyre Insert System) is a lightweight, highly tunable, high-efficiency, tubeless tyre insert. Tyre assemblies are one of the most important performance factors for any bike. They provide all the grip to the ground, they serve as a critical first element of the bike’s suspension and they provide essential support to the cornering forces that the bike encounters. Pressure choice is always a compromise to balance these requirements.

Available in 27.5" or 29" sizes with a standard length OPTIS valve or a longer OPTIS valve (ETA TBD) for taller carbon rims. Replacement inserts also available separately (OPTIS valve needed).

Why use OPTIS?

OPTIS prevents tyre burping. By pressing the tyre against the rim and preventing gaps from opening, burping becomes almost impossible.

OPTIS allows for lower tyre pressures. The insert is inflated to a higher pressure than the tyre, keeping the tyre supported while allowing the main volume to be at a lower pressure that provides optimum grip.

OPTIS protects the rim and tyre against impacts. The insert’s higher pressure provides protection against impacts, reducing the chances of tyre pinching and rim damage.

OPTIS locks the tyre bead and provides a temporary run-flat period if the tyre is damaged. OPTIS will securely hold the tyre to the rim for a short period of time if the tire is ever critically damaged and loses its air. This can allow for a brief run-flat period that gives the rider more control than they would otherwise have, providing the time needed to stop the bicycle.

OPTIS is lightweight. Wheel assemblies using OPTIS are significantly lighter than most of the alternative tubeless insert set-ups, while also providing greater protection. The OPTIS insert’s bead locking feature and tyre support can also allow for lighter than typical tyre and rim choices, resulting in overall weight savings.

OPTIS installation is easy and helps to seat tyres. Unlike foam inserts, OPTIS installs as easily as a traditional inner tube, and inflation starts the process of pushing the tyre beads outward to ease tire inflation.

OPTIS allows for low rolling resistance. By facilitating the use of lower pressures and lighter tyres, rolling efficiency on rough surfaces is greatly improved.
