Super lightweight tubeless sealant with hi-tech fibers and synthetic latex formula to protect against punctures up to 7 mm. Bar Keeper maintains tire pressure at the desired level, allowing you to keep riding. Durable formula developed and tested with professional teams. Effective at tire pressures of up to 8 bar and does not clump. Dynamic Barkeeper is a tubeless sealant made from synthetic latex with hi-tech fibers that protects against punctures and keeps tire pressure at the desired level. Thanks to its unique formula, it adheres to the inside of the tire walls and perfectly seals the connections between tire and rim. Barkeeper lasts longer than other tubeless sealants, does not clump, and can be applied without removing the tire. Works in tires for road, gravel, and MTB bikes, with a pressure range of 1 to 8 bar and temperatures between -20°C and +50°C. 100% safe to use, ammonia-free, allergy-free, non-corrosive, and skin-friendly. Application: Shake Barkeeper well before use to ensure even distribution of the hi-tech fiber particles. Mount the tire on the rim and inflate it initially without sealant. Next, release the air from the tire and remove the valve core. Fill the desired amount of sealant into the tire. Reinsert the valve core and inflate the tire. To distribute the sealant well inside the tire and rim, we recommend a short ride or rotating the tire. Safe travels!.
