Why We Love It
When a puncture threatens to end your ride, SILCA Ultimate Tubeless Sealant is designed to keep you rolling. Developed for tubeless tyres demanding maximum puncture protection without compromising performance, this premium tubeless sealant combines fast sealing action with exceptional durability. SILCA's tubeless tyre sealant helps maintain tyre pressure after punctures, giving you the confidence to ride further with less down-time dealing with flats.
Talk Nerdy To Me
SILCA Ultimate Tubeless Sealant uses a unique foaming natural and synthetic latex formula combined with chopped carbon fibre strands to create a highly effective sealing system. As air escapes through a puncture, the sealant foams and carries carbon fibres directly to the hole, forming a reinforced plug that seals larger punctures more efficiently than traditional latex-only formulas. The ammonia-free formula is engineered for extended longevity inside the tyre, reducing the frequency of top-ups while maintaining reliable sealing performance. SILCA Ultimate Tubeless Sealant can seal punctures up to 6mm and remains effective across a wide range of riding conditions and tyre pressures.
