Stan's No Tubes Race Sealant
Best flat prevention for competitive cyclists.
This is the heavy-duty insurance policy for competitive riders who can’t afford a mid-race flat. By packing in extra-large sealing crystals, it handles punctures that would leave standard formulas weeping. You sacrifice the convenience of injector-based maintenance for the peace of mind that comes with near-invincible tire protection.
