Works up to 8 bar tyre pressure, doesn’t ball up and is compatible with CO2 cartridges.

Dynamic Barkeeper is a Hi-Tec fiber synthetic latex tubeless sealant that protects against punctures and keeps your tyre pressure at the desired level. Due to its unique formula, clings to the inside of tyre walls and seals tyre/rim connections perfectly. Barkeepers lasts longer than other tubeless sealants, does not ball up and can be topped up without removing the tyre. Works in tyres of road, gravel and MTB bikes with pressure between 1 and 8 bar, in temperatures between -20°C to +50°C and is compatible with CO2 cartridges. 100% safe to use, ammonia free, allergy free, non-corrosive, skin safe.

Application: Shake the Barkeeper before use to ensure an even distribution of the Hi-Tec Fiber particles. Mount your tyre onto rim and inflate initially without sealant. Deflate the tyre and remove the valve core. Inject the desired amount of sealant in the tyre. Re-insert the valve core and inflate the tyre. Go for a short ride to disperse the sealant around the inside of your tyre and rim. Have a nice ride!

Ultimate cornering grip on wet or dry roads. Reinforced puncture resistance. Smooth construction that lowers rolling resistance and makes rough asphalt feel like freshly laid asphalt. The Corsa PRO combines the convenience of a tubeless-ready clincher platform with the reputation of the world's most successful race tyre, proven in the thin air of France's highest mountain passes and the spirited finishes of the classics. This is the tyre also used by the riders of Team Visma | Lease a Bike.

Grand tours, monuments, one-day races, criteriums - the Corsa PRO TLR is the tyre of choice for the world's strongest riders in the most prestigious races.

Racing in rain, wind, and the kind of variable conditions where you pin your number on a gilet instead of a jersey? Rolling over sections of French pavé or chalky limestone gravel? Confronting rough chip seal or wet conditions – or a combination of both – that warrant letting a little air out of the tires on the start line? Those are the days our riders choose the Corsa PRO Control.

True to its name, the Control updates the Corsa PRO with additional grip for rain slicked tarmac, groomed gravel stretches, and treacherous cobblestones alike. The supple construction reduces rolling resistance, and increased puncture protection resists the occasional sharp gravel or cobble peak. Proven on the most grueling stones of Roubaix. Engineered for anything else the world can throw at it.
