What Makes SILCA Ultimate Tubeless Sealant Better Than Standard Latex?

SILCA Ultimate Tubeless Sealant does what standard latex sealants can't: it seals holes up to 7.5mm, roughly 25% larger than conventional alternatives. The formula combines a unique foaming latex base with chopped recycled carbon fiber (6mm, 9mm, and 12mm strands reclaimed from bicycle frames, carbon wheels, racecars, and aircraft components) suspended evenly throughout the liquid. When a puncture occurs, the sealant flow carries carbon fiber directly to the hole, where thousands of micro-bubbles collapse and deposit fibers over the gap, forming a carbon dam that seals larger cuts that latex alone cannot handle.

Works at higher pressures than conventional sealants and seals more reliably on larger cuts. 16oz bottle. Compatible with all tubeless-ready tires and rims. Made in the USA.
