TLR Mountain and Gravel sealant was developed through extensive real-world testing and Factory Athlete input. The ecological formulation seals punctures up to 6mm in both mountain and gravel tires. Particulates stay mixed longer to maintain proper ratio during multiple fill-ups, and the sealant installs easily through valve stems with consistent puncture sealing performance. The sealant is ammonium-, protein-, and latex-free, so it poses no risk of allergic reactions and will not damage bike parts.
