Odyssey Optis Tires Insert

WHAT IS OPTIS? OPTIS (Odyssey Pneumatic Tire Insert System) is a lightweight, highly tunable, high-efficiency, tubeless tire insert. Tire 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).
