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.


- Shake the bottle
- Deflate tyres and add Barkeeper
- Inflate and go for a ride!

Inject the following amount of sealant in the tyre:

Roadbike 30 – 45 ml
MTB 26” 60 – 75 ml
Cross/ Gravel 60 – 75 ml
MTB 29” 100 – 140 ml
Downhill MTB 120 – 140 ml

Super lightweight tubeless sealant with Hi-Tec fibers.

Dynamic Barkeeper is a Hi-Tec fiber, synthetic latex, tubeless sealant. The unique formula clings to the inside of the tyre and rim and therefore seals holes quicker than any other sealant. 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.

Have a nice ride!

Great - the best

Tried other sealant brands for roadbike. But this barkeeper is so so so awesome. Like big.
Hard to see on bottle how many ml. you are adding.

The bartender kit is a fantastic and easy to install kit. The difference to the “standard” is enormous. Quieter and firmer, but above all comfortable. Compare it to walking on clogs or slippers😉And the certainty that small holes do not disturb your trip.

Ik ben overgestapt vorig jaar op Barkeeper en heel blij mee.
Zowel voor racefiets, MTB en strandbike.
Laatste 2 wel eens lek gereden in verleden en toenmalige sealant werkte niet optimaal.
Afgelopen seizoen nergens last van gehad. Ongetwijfeld met strandbike lek gereden….maar niks van gemerkt 🙌🏼
Dus top Sealant

Good product

The sealant does it job, easy to insert, good job
