TUBE ODY OPTIS TBLS INSERT 29 28-40mm INSERT & VALVE SV YL

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

Dual valve mechanism allows inflating the insert, and surrounding tire to two different pressures where the higher pressure insert supports the tire, and the lower pressure zone improves grip and performance

If tire pressure is suddenly lost due to a puncture, the interior higher pressure OPTIS allows the rider time to stop without losing control

Optis pressure the tire into the bead, preventing burping as well as helping to seat the bead and easing tire installation and seal
