Dynamic Barkeeper Sealant is a tubeless tyre sealant that seals punctures as you ride, without you needing to stop. It suits every tubeless setup, road through to mountain bike, and is the difference between a puncture ending your ride and you never noticing it. The latex-based formula carries sealing particles that plug holes up to around 6mm as air escapes, and it works across a wide temperature range so it stays effective through a New Zealand winter. It also seats new tyres reliably, which saves time and frustration on installation. Key features Seals punctures up to approximately 6mm on the move Works across a broad temperature range Suitable for road, gravel and mountain bike tubeless setups Available in 250ml and 1,000ml Also helps seat stubborn tubeless tyres Top up every 3 to 6 months; sealant dries out over time whether you puncture or not. The 1,000ml bottle is the sensible buy if you run tubeless on more than 1 bike. We can set your tubeless up in the workshop.
