Lower rolling resistance, more comfort, no flats. No matter if you ride on- or off-road, the key to the optimal experience is the right sealant. You want to seal punctures quickly and prevent pressure loss. This is why we developed Barkeeper, providing the optimal tubeless experience for all cyclists.

Why Barkeeper?

Barkeeper lasts longer than other sealants, it does not ball up or dry out. It can be topped up without removing the old sealant. 

It is engineered for use on- and off-road, with pressures between 1 and 8 bar. Barkeeper works between -20°C to +50°C and is compatible with CO₂ cartridges. 

The use of Hi-tec fibers in the sealant, ensures larger punctures are sealed fast and permanently.

The formula is ammonia free, hypoallergenic, skin safe and non-corrosive.
