SilcaUltimate Sealant, 500ml(Return to Product Page)

I've had good luck with the Silca sealants, it's very sticky and seals up almost anything even on a road tire for me. I like that this is injectable now, I don't have to break the bead of the tire to do the pour in method. Just go slow with the injector and it won't clog up with fiber bits.

I haven't had this long enough to test the 6 month claim, but if it lasts that long, this is a game changer. I can do a spring/fall switchout and be good for the year.

Would love to tell you about its sealing ability, but after several tough rides, I haven't had a puncture. I like that it isn't a neon color, unlike some brands, and is thicker, making setup and dismounting tires less messy.

Does a fantastic job of sealing tubeless road bike tires. No leaks from minor cuts in tire. Also helps with normal time leakage of air when bikes sits for 3-4 days

I had two small punctures that took a long time to seal. A day or two later on my next ride they reopened. After this happened a couple times I ended up plugging both the holes. One the plugged holes started leaking a week or so later. Going back to Orange Sealant which worked well last year but has a short refresh period.
