SILCA Ultimate Tubeless Tire Sealant W/FIBERFOAM | Long Lasting, Fast Sealing Bike Tire Sealant | Tubeless Sealant for MTB, Road, CX and Gravel Bicycle Tires | Tire Sealant Bicycle (32oz Sealant)

Great product and excellent reviews elsewhere. Great price at black friday

I've been riding tubeless tires for over a decade on my mountain bikes and about 5 years or so on road and gravel. I've tried all the major brands from Stan's to Orange Seal, etc. While those sealants work well too, I've found myself purchasing this Silca offering exclusively in the last few years because it simply delivers and tends to stay in it's liquid form longer than most. Sealant works very well, especially on tubeless gravel and road tires. Because of the particles in the sealant, this has to be poured into the tire rather than "injected" through the valve stem, otherwise it will likely clog the injector or the valve stem. Because it's Silca, you know the quality is there. The product works very well and would recommend highly.

Produit hors d'usage avec particules solides dans la bouteille. Certainement périmé. NE PAS ACHETER.

Excellent sealant - application is a bit flawed as the new version can be injected, but this stuff definitely works, saved me from a lot of flats on our awful UK roads!

I have been reading reviews on line about this sealant and that proof the be correct. I have put the sealant to my continental 5000 tyres and I have covered more that 7000 km with out any puncture. I would recommend Silca to anyone.
