Dynamic Barkeeper Tubeless Sealant

Lower rolling resistance, more comfort, and never get a flat again. Whether you ride on the road or off-road, the key to an optimal tubeless experience is the right sealant that seals holes quickly and prevents pressure loss.

Dynamic's Barkeeper delivers. The unique formula adheres to the inside of the tire and the rim, sealing holes faster than ever. Barkeeper lasts longer than other sealants, does not clump, and does not dry out. It can be topped up without removing the old sealant.

The formula is developed for on-road and off-road use with tire pressures between 1 and 8 bar. Barkeeper works between -20°C and +50°C and can be used with CO₂ cartridges. The Hi-Tec fibers ensure that a puncture is sealed quickly and permanently. Barkeeper is ammonia-free, hypoallergenic, safe for the skin, non-corrosive, and safe for carbon.
