Its advanced formula lasts up to 6 months, providing strong, eco-friendly tubeless tyre protection for year-round cycling. ## Description SILCA Ultimate Tubeless Tyre Sealant offers cutting-edge FiberFoam technology that uses recycled carbon fibers to deliver superior sealing performance for tubeless setups. This advanced formula seals punctures up to 7.5mm, outperforming other tyre sealants on the market. With the ability to function effectively in temperatures as low as -12 degrees Celcius, this sealant is perfect for year-round riders seeking reliable protection. The FiberFoam technology in our tubeless sealant evenly disperses carbon fibers through a foaming latex formula, creating a strong, lasting seal that prevents air loss, even under high pressure. Tested to be 25 percent more effective at sealing large punctures than conventional technologies, our formula ensures a robust repair on the trail or road. Additionally, our Silca sealant includes antifreeze agents to maintain performance in low temperatures, sealing 6mm holes at -7 degrees Celsius. To ensure longevity, the sealant lasts up to 6 months, with replenishment recommended every 90-120 days for best results. The replenisher is especially useful for sealing porous tires or rejuvenating the existing silca bike tyre sealant sealant. Unlike other products SILCA's formulation utilises sustainable carbon fibers reclaimed from recycled sources like bicycles and race cars. This results in a sealant that is not only effective but eco-friendly . For optimal results, avoid CO2 and talc powder during installation to prevent sealant hardening.
