Description

STAN'S RACE DAY anti-puncture tyre sealant (500 ml) is the extra-durable sealant from Stan's NoTubes, developed with elite athletes and their mechanics for racing and long-distance events.

Based on the Original formula, it contains 200% more sealing crystals, along with extra-large (XL) crystals capable of sealing punctures up to 8 mm. An advantage for downhill and enduro riding, where cuts and impacts are common.

This sealant must be poured directly into the tyre over the bead: it cannot be added through the valve or used with an injector. A visual check of the sealant level every 2 to 3 weeks is recommended, as it dries faster than the Original formula.
