About Challenge
In 1990, Max Brauns was driven by a passion for hand-crafted performance tyres and moved to Thailand, where the World's best natural rubber (rather than artificially-produced petroleum-based rubber) could be sourced. In 2000, Challengetech was born.

High performance tubeless systems deserve high-performance tubeless sealants. The SMART Sealant was designed to work with both vulcanised and handmade TLR and Tubeless tyres. This non-allergenic, ammonia-free formula can seal up to 6mm cuts, remains liquid in the tyre for up to 6 months, doesn't coagulate with Co2 use, and doesn't damage rims or tyres 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.
