Our new TLR Sealant was custom-designed in partnership with a leading laboratory for tire sealants, and it also underwent extensive real-world testing with our Factory Athletes. What we developed is an innovative, ecological formulation thats the answer to the requirements that riders like youve been demanding. It will immediately seal punctures up to 6mm, whether it be on a road or mountain tire, as well as across global temperatures [-20° to 70°C]. Natural, micro holes in the sidewalls will seal well, and the system is safe for use with latex inner tubes, even inside tubulars. Please note that this sealant is ammonium-, protein-, and latex-free, so it holds no potential for allergic reactions, and theres no risk of it creating damage to bike parts.
