{"title":"Tubeless Sealant \u0026 Tyre Inserts","description":"\u003cp\u003eTubeless setups are the single biggest upgrade you can make to how a bike handles Indian roads and trails — fewer punctures, better grip, lower pressure.

The NAC Instant Seal Tyre Sealant uses a micro-bead formula that rushes to the puncture site and seals holes up to 3mm instantly — thorns, glass shards, and trail debris are plugged before you even notice the pressure loss.

The moment a puncture occurs, micro-beads in the formula rush to the hole, build up, and seal it — all while you keep riding.
