Wtb TCS Tubeless Tire Sealant

What Our Gearhead® Experts Are Saying:"I’ve tried most tubeless sealants out there, and this one just works. It seals bigger punctures fast, even in freezing temps, and doesn’t dry up as quick as others. It’s been my go-to for both trail bikes and gravel builds."When a puncture strikes mid-ride, we don’t want to think—we want to roll. That’s why we reach for WTB’s TCS Tubeless Tire Sealant. This 16oz bottle delivers enough sealant for multiple setups and offers peace of mind on everything from singletrack laps to gravel grinds. With a formula that’s been refined through five versions, WTB’s sealant works instantly to plug punctures up to 6mm in size using mica-based particles and synthetic latex without relying on ammonia-based evaporation. Unlike some sealants that only work in perfect conditions, this stuff stays fluid and effective in temps as low as 15°F. It’s safe for carbon rims, compatible with all tubeless systems, and comes with clear measuring gradients so you know exactly how much you’re using.
