The Stan's NoTubes DART Tubeless Repair Refill is a crucial addition to any bike maintenance kit for those venturing out on rough terrain. It's a set of six DART plugs, all compatible with Stan's DART Tool models and designed to repair punctures beyond the capabilities of standard tubeless sealants. The laser-cut woven material adapts to the shape of the puncture, while its reactive treatment bonds with Stan's Original and Race Day sealants for a permanent repair. With the excess material naturally wearing away over time, your ride quality remains unaffected. Packaged in a resealable, biodegradable bag, these refills are always ready for action, helping to ensure uninterrupted cycling adventures.
