Dynamic Barkeeper Tubeless Sealant 1L Bottle

Dynamic Barkeeper Tubeless Sealant delivers reliable puncture protection for road and off-road cyclists seeking a lightweight, high-performance solution. Its advanced synthetic latex formula, reinforced with Hi-Tec fibres, seals holes rapidly and remains effective longer than standard sealants. Barkeeper adheres to the tyre and rim, preventing balling and allowing easy top-ups without removing old sealant. 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, skin-safe, and non-corrosive composition ensures safe handling and environmental responsibility.
