Silca’s New Tubeless Sealant Lasts Longer and Seals Bigger Punctures
Silca updates its tubeless sealant with a longer-lasting formula, better puncture sealing, and easier application. Available now, starting at $6.
Silca’s tubeless sealant just got a major upgrade, addressing key concerns from casual riders while maintaining the high-performance sealing that pro racers need. The new formula blends natural and synthetic latex for improved longevity—lasting 6 to 12 months before needing a top-off. It also remains injectable through the valve without clogging, thanks to optimized carbon fiber strands and advanced foaming agents. Most impressively, Silca is so confident in its formula that it offers a $500 payout to sponsored athletes if a puncture fails to seal during a race.
Pricing is competitive with leading brands: $24 for 500ml (8oz) and $6 for 65ml (2.2oz). Available in 1L, 500ml, and 65ml sizes.
