Dynamic Barkeeper Tubeless Sealant 100ml Bottle

Dynamic Barkeeper Tubeless Sealant delivers rapid, reliable puncture protection for road and off-road cyclists. Its advanced synthetic latex formula, reinforced with Hi-Tec fibres, adheres to the tyre and rim for swift, lasting seals—even on larger punctures. Barkeeper remains effective longer than standard sealants, resists balling, and can be topped up without removing the old product. Suitable for pressures from 1 to 8 bar, it performs in temperatures from -20°C to +50°C and is fully compatible with CO2 cartridges. The ammonia-free, hypoallergenic, non-corrosive formula is safe for skin and environmentally considerate.
