SILCA Ultimate Tubeless Tire Sealant W/FIBERFOAM | Long Lasting, Fast Sealing Bike Tire Sealant | Tubeless Sealant for MTB, Road, Gravel Bicycle Tires | Tire Sealant Bicycle (8oz Sealant with Carbon)
- Puncture Protection | SILCA flat tire sealant makes punctures a thing of the past with the power of carbon fiber infused bike tire sealant. The recycled carbon fibers which come from bicycle, racecar, and aircraft components provide structure to seal the largest punctures while maintaining longevity of endurance specific bike sealant.
- The Perfect Sealant | The problem with most tubeless bike tire sealant has been that they work great but dry out quickly, or they can last for a season but don’t plug large holes. We have created a cycling sealant that can finally do both. With a full latex foam sealant combined with performance foam and Carbon Fibers we can finally have a tubeless sealant that lasts for 7-9 months and seals holes 6+mm in diameter.
- Compatible With All Tires | A proprietary bicycle tire sealant combined with 6, 9, and 12mm chopped carbon fibers leads to the best tubeless tire repair kit tool made for high pressure road tires and low pressure fat bike and mountain bike and all pressures in between.
- Application Process | Starting with a clean, tubeless tire, use the 'pour in' method when installing on a tubeless rim. The quick sealing power makes it impossible to use a syringe or through the valve stem. When we say we can seal a +6mm, we mean it. The key is the carbon fiber that rushes to a puncture or open source and creates a fiber dam coagulant for a extremely effect seal
- Manufactured In The USA | Silca ultimate bike tire sealant tubeless tires is manufactured in the USA and bottled and shipped from SILCA HQ in Indianapolis, IN.
