DYNAMIC – BARKEEPER TUBELESS SEALANT
High-performance tubeless sealant for road, gravel, and MTB.
Dynamic Barkeeper is a super-lightweight, high-performance tubeless sealant developed to deliver fast sealing, long service life, and minimal rolling resistance. Formulated with Hi-Tec fibres and synthetic latex, it clings to the inside of the tyre and rim, allowing punctures to seal faster and more reliably than conventional sealants.
Designed by Dynamic, Barkeeper does not ball up or dry out over time and can be topped up without removing existing sealant. It performs across a wide pressure range and extreme temperatures, making it suitable for both on- and off-road use.
