In tests, Barkeeper Pro seals a 6 mm puncture at 4 bar in a single wheel rotation at 30 km\/h, that is in \u003cstrong\u003eless than 0.5 seconds\u003c\/strong\u003e, and closes holes up to 8 mm.

It doesn't clump, doesn't dry out and can be topped up without removing the previous sealant. It works between 1 and 8 bar, from -20 to +50 °C, is CO2-compatible, carbon-safe, ammonia-free and non-corrosive.\u003c\/p\u003e\u003ch3\u003eFitting and quantity\u003c\/h3\u003e\u003cp\u003eShake the bottle to distribute the Hi-Tec fibres, fit the tyre and seat the bead without sealant. Then deflate, remove the valve core and inject the desired amount, refit the core and inflate to riding pressure. Amounts: 30-45 ml for road, 60-75 ml for gravel and 26-inch MTB, 100-140 ml for 29-inch. With new tyres, use the upper end of the range.\u003c\/p\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eType\u003c\/strong\u003e: racing tubeless sealant.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSealing speed\u003c\/strong\u003e: 6 mm at 4 bar in less than 0.5 s.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eHoles\u003c\/strong\u003e: up to 8 mm.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePressures\u003c\/strong\u003e: 1 to 8 bar.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eTemperatures\u003c\/strong\u003e: -20 to +50 °C.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDurability\u003c\/strong\u003e: doesn't dry out or clump.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFormula\u003c\/strong\u003e: ammonia-free, hypoallergenic, non-corrosive.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e: all tubeless wheels and tyres, CO2.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003ch4\u003eHow does it differ from standard Barkeeper?\u003c\/h4\u003e\u003cp\u003eThe Pro has a viscosity optimised to spread faster inside the tyre and seals holes up to 8 mm in record time; it is designed for racers who don't want to lose time.\u003c\/p\u003e\u003ch4\u003eWhy use the higher amount with new tyres?\u003c\/h4\u003e\u003cp\u003ePart of the sealant is used to seal the porosity of the new tyre.
