Nutrak Tubeless Tyres Sealant Hi Fibre 1L is engineered for serious cyclists seeking reliable puncture protection across varied terrains. This synthetic latex-based sealant is optimized for racing, seamlessly adaptable to both high- and low-pressure tubeless tyre systems. Whether you're tackling smooth road surfaces, rugged gravel paths, or challenging mountain trails, this sealant provides robust and consistent performance.
Featuring Nutrak's advanced formula, it effectively seals punctures up to 7mm and uniquely coats tyre sidewalls, offering enhanced protection where it's needed most. The inclusion of extra puncture sealing fibres gives riders peace of mind to push their limits—whether descending technical downhill runs at low pressure or powering up steep mountain roads at high pressure. Its free-flowing consistency ensures easy setup by thoroughly filling all gaps between bead and rim, including those with rim inserts.
Designed for durability, Nutrak Tubeless Sealant Hi Fibre lasts approximately six months under typical UK atmospheric conditions without separating or forming lumps inside the tyre. The synthetic latex composition is wheel, tyre, and CO2 friendly, containing no ammonia, making it an excellent choice for Tubeless Ready and UST setups. For optimal use, adjust the quantity based on tyre size: Road Racing requires 30-50ml, 26" MTB 60-80ml, 27.5"/650B 80-100ml, and 29" MTB 100-120ml.
