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.

Roadbike 30 – 45 ml

MTB 29” 100 – 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!

Easy to use

Eas to use. Tires are solid tight and directly usable.

Not good to see how much is use and/or still in the bottle.

Pure Sorcery!!!

I don't know what the guys put in this stuff but its magic!

it's the only sealant that keeps the paper-thin thunder burt evo liteskins sealed and inflated - it cleans up real easy and it actually smells quite nice!!

Eerste maal tubeless

Ik volg een cursus fietshersteller. Leerkracht had mij overtuigd om mijn gravelbanden even tubeless te maken. Product doet wat het moet doen. Eerst zorgen dat het tubeless velglint er goed op zit. Dan banden oppompen dat ze klikken op de velgen. Dan de lucht eruit en ventieltje eraf. De Barkeeper schudden en product in het ventiel spuiten. Band terug op druk en wat laten ronddraaien en klein testritje maken. (Zodat de melk overal in de band zit) Klaar is kees. Heel tevreden. Enige minpunt is dat ik persoonlijk niet goed kan aflezen aan de fles hoeveel product er reeds in de band zit. Er zit een soort van meetlat in de fles maar door het schudden en goed product vrij dik is, is het erg moeilijk aflezen van de fles.
Heel tevreden! Gelijk heeft mijn leerkracht, tubeless rijden is nog zoveel comfortabeler. Nu kan ik de bandendruk eindelijk laten zakken zonder dat ik bang hoef te zijn op stootlek te rijden.
