STR Tubeless Sealant

After riding for multiple seasons with tubeless set-ups on both our trail rigs and road bikes, we're pretty damn sure we'll never go back to a traditional clincher set-up, especially seeing Utah's trails and roads are littered with flat-causing goatheads and abrasive rocks. Gain the numerous benefits of a tubeless tire set-up with the STR Tubeless Sealant on your mountain, gravel, and road bikes.

This premium sealant features Web Tech, which quickly fills the gaps caused by sidewall slits and thorny punctures from stopping your ride short. Flow Motion enables longevity without drying up prematurely and requiring additional sealant inside your tires. This formula evenly seals from bead-to-bead for an optimal tubeless set-up. It's CO2-compatible, meaning you won't mess up the sealant if you use CO2 inflation cartridges to gain additional tire pressure.

  • Web Tech quickly seals up punctures and slits

Seems to work ok. Not sure if it's on the same level as Stan's or Orange Seal though. Was surprised to have some small punctures that didn't seal up.

Seems to work well

I've used it several times

Got a bottle of this to try out compared to the stuff we all use, you know what I'm talking about. It seems a little thicker in consistency, and doesn't have a bad ammonia smell. I've had a couple hundred miles on the tires I installed it in, and no flats so far. I did just remove one tire to check sealant levels and it is still nice and fluid, so all is working well so far. I will update the review later down the road, but all seems good so far!


Can this product get injected through a presta valve stem when using tire inserts like cushcore?
