It is injectable through your valve, seals a 6mm+ puncture, and lasts up to 6 months. It is the perfect sealant for those looking for the ultimate sealing power, longevity, and ease of use.SPECIFICATION Seals 6mm+ punctures Injectable through the valve Lasts 6+ months Proprietary Natural and Synthetic Latex blend Optimized carbon fiber strands Advanced Foaming agents to carry carbon strands to a puncture Available in 1L, 500ml, and 65mlThe original sealant formulation, released 2.5 yearsago, was designed primarily for effective puncturesealing by maximising the surface area of the liquidlatex for enhanced performance. Pro racers valued itsconvenience, as they frequently changed tyres based onrace conditions and could easily pour in fresh sealantwithout needing to inject it through the valve. However,we heard two main concerns from more casual cyclistsitdried out quickly when not in use, and its composition ofthe longer strand carbon fibre made injection difficult andproblematic, leading to a potentially messy installation ifnot handled carefully.Lastly, the old Natural Latex formula needed a two-stepprocess to stay liquid longer. That has been eliminatedwith our new blend of natural and synthetic latex.
