Mountain and gravel riders running tubeless who want a reliable, locally made sealant for set-ups and top-ups.
Shred Ultraseal is a tubeless tyre sealant from Australian brand Shred, made and owned here. It is formulated to seal a range of puncture sizes and hold air pressure, so a thorn or sharp rock doesn't end your ride.
It works with all off-road tubeless tyre systems and can also be used in tubes. The 250 ml bottle has a squeeze top that makes it easy to add sealant straight through a valve with the core removed.
Sealant dries out over time, especially in warm Australian summers, so topping up every few months keeps your tyres protected.

Shake well before use. How much you need depends on tyre size; wider mountain bike tyres take more than gravel tyres.
Top up regularly
Check sealant every two to three months, sooner in hot weather. Pull the valve core and dip a zip tie in to see if there's still liquid inside.
Spin it round
After adding sealant, reinflate and spin and tilt the wheel so it coats the whole tyre and bead before you ride.
