Dynamic Bar Keeper Pro Tyre Sealant

Dynamic Bar Keeper Pro puncture sealant is designed for those using tubeless wheels on road, gravel or MTB bikes who want to seal punctures without stopping. It seals holes up to 8 mm and, according to the manufacturer, seals a 6 mm hole in less than 0,5 seconds at 4 bar and 30 km/h. The Hi-Fibre synthetic latex formula is ammonia-free and compatible with all tubeless rims and tyres.

Choose the 1000 ml pack if you want to keep a supply for several wheels over time. It is compatible with inflation using CO2 cartridges, useful when you need to inflate quickly. Remember that it is designed for tubeless wheels, so check that your rim and tyre are tubeless compatible.

Established in the 1980s within a German distributor, Dynamic is now based in The Hague, Netherlands. It offers cleaners, lubricants, waxes, greases and tools to care for your bike, from everyday rides to weekends on two wheels. It has operated independently since early 2020.
