High-performance tubeless systems deserve high-performance tubeless sealant. The SMART Sealant was designed to work with both vulcanized and handmade TLR and Tubeless tires. This non-allergenic, ammonia-free formula can seal up to 6mm cuts, remains liquid in the tire for up to 6 months, doesn't coagulate with CO2 use, and doesn't damage rims or tires with extended use. Installation is straightforward using the application tip and there is no need to shake the bottle. Available in a 250ml/8.5oz bottle.

The Challenge threaded inline valve extenders add 41.5mm length so that your valves will protrude thru deeper dish rims allowing you to attach a pump. They are compatible with inner tubes and tubular tires that include removable valve core Presta valves. They also include rubber gaskets for an air-tight fit. The kit includes two alloy extenders and a plastic tool.
