Optis Tubeless Tire Insert - 27.5" x 28-40mm Insert w/ Standard Presta Valve
MPN: ODT-500-271 · UPC: 630950941315
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. OPTIS separates the function of the bikeʼs grip from its suspension and stability by turning the tire into a two-chamber system. This allows for lower tire pressures while the insert is inflated to a higher pressure than the tire, keeping the tire supported while allowing the main volume to be at a lower pressure that provides optimum grip.
- ✓ Riders can separately tune the tire's grip and internal support through a dual-valve design, allowing for lower tire pressures and ride characteristics that would not be possible with a traditional tubeless or foam insert set-up
- ✓ Instead of forming to the internal tire casing like an ordinary inner tube, OPTIS cinches down against the tire bead and hugs the rim when inflated. This creates a bead lock that prevents burping, protects the rim from impacts and offers a limited amount of run-flat protection when the tire is damaged or punctured
- ✓ OPTIS reduces rolling resistance by facilitating the use of lower pressures and lighter tires. Rolling efficiency is greatly improved on rough surfaces without the hysteresis losses often associated with foam inserts
- ✓ OPTIS is lightweight, adding less than 90g per wheel to an ordinary tubeless set-up and provides greater protection than traditional inserts that are much heavier
- ✓ Valve is constructed from Aluminum, Insert is made from Nylon and TPU (Thermoplastic Polyurethane)
- ✓ Standard Presta Valve w/ Insert
- ✓ The maximum allowable rim thickness at the valve hole is 18mm or 0.70”
