SILCAUltimate Tubeless

I've ben running with Stan's in my tires for a while now, and I've been dealing with chronic leaks. Simply put, Stan's regular cannot handle the pressure of road tires. I've got latex all over my bike frame from the futile spewing of sealant as the wheel spins. Stans racing might be better but doesn't last; it's more of a race-day thing.The leaks Stan's couldn't fix are not massive punctures, but I'm on a road bike and I need my tires to hold up to 80 psi.The first time I put the Silca into the rear tire of my commuter bike and pressurized the tire, two leaks immediately popped. Small holes that Stans had never been able to seal at 80 psi. I spun the tire and the leaks were sealed. That was that. I've got miles on the tire now to prove that the leaks are sealed for good.When you pour the goop into your tire you see why you could never use an injector to push the sealant into your tire. There are lumps of bluish fibers are just waiting to clog something.Silca will clog any tool you use to inject the goo into your tires. The great part is that a dose of Silca can last for up to a year with periodic applications of the replenisher, which will work fine with an injector (the replenisher does not include the fibers). With that in mind, you may want to buy a smaller bottle of the sealant than you would other brands.

If you're using Silca Ultimate tire sealant, you have to get the replenisher. It extends changing out sealent up to a year plus and it works. Absolutely worth it..

Silca sealant is the only one I've found that reliably seals 28c road tires at 80 psi. This refill easily injects through the valve stem. The 4oz size is convenient for road and gravel tires, but you'd need 2 bottles for MTB tires. I wish Amazon had the 32oz refill size so I didn't need to throw away so many 4oz bottles and it would be more cost effective.

I ride in some pretty bad conditions and down Urban alleys with broken glass and stuff like that. I'm often amazed when I get home when I see a smear of sealant on the outside of my tire and realize that I got a big puncture and never knew it while I was riding.If I didn't see it myself, I wouldn't believe it

At first the claims seem great. It has strips of fiber that will seal larger punctures. It pours in fine.Then your tire starts leaking air and you are wondering what is the deal. This is what happened to me.I set up DT Swiss wheels with this stuff on a factory tape job that was immaculate. About four weeks later the spokes were leaking air. At first I just thought it was the tape job. When I popped the tire off it was terrible. All the sealant was a solid mass and left behind a ton of residue that I had to use alcohol to get off the rim. It took tons of alcohol and elbow grease. The tires are trash since I cannot get the seal needed for tubeless anymore even though I cleaned them with alcohol also. I have to run tubes now.TL:DR - If you want to change the sealant after a few weeks and love to clean up hunky messes, this is the sealant for you. This stuff is the worst.

I got out my syringe that I've used before with Stan's tubeless latex with no trouble.I tried to suck the fluid into the syringe from the bottle, but the carbon fibers immediately clogged the hose. So I back flushed the fluid back into the bottle until the syringe was empty.Since I couldn't suck it in, I opened the syringe and poured the liquid into it. When I started pushing the liquid into the tube the fibers again quickly accumulated at the outlet of the syringe and clogged it.I found that by repeatedly pulling the plunger out to clear the clog and then beginning to push again, I was able to get the fluid in over the course of about 10 minutes. (this should have taken about. a minute)Boy is it a pain in the butt to put in. But it's difficult because it seems to be effectively sealing a hole that is probably 3 mm across. (huge). I have no doubt that those pain in the butt carbon fibers will make this stuff seal very very well.

Just the ticket for hard to seal tubeless tires. Especially road bikes. Read the directions as this is too thick to force it through the valve stem even with the core removed. Best tire sealant I have found.

I've been running tubeless on my MTB bikes for over 8 years. Started running tubeless on my road bikes about 3 years ago. It's been a game changer. If you do have a puncture that's to large for the sealant I use a tire plug. Add a little air and you back riding in minutes. Most times I didn't know I had a puncture, until I saw some over spray from the sealant on my bike frame.Water soluble, washes right off. My sealant lasts all Spring and most of Summer before I need a refresh. Which is super easy to do.

Works perfect for plugging holes

This tire sealant is the best I've used so far! It provides consistently reliable performance and is incredibly easy to apply—I’d recommend pouring it directly inside the tire instead of through the valve for the best results. It ages well and doesn’t deteriorate quickly, which is a huge plus. Delivery was outstanding, arriving ahead of schedule—couldn’t ask for better! I’ll definitely be returning to this seller soon for a larger bottle. Thank you!

Bloody annoying, is only made to top up step one. Not obvious

Ich habe bereits mehrere Marken von Dichtungs-Flüssigkeiten getestet und keine ist so gut wie die von Silca. In diesem Fall lohnt sich total ein bisschen tiefer in der Tasche zu greifen für dieses Produkt. Löcher werden dank der kurzen Trocknungszeit schnell wieder zugedichtet, daher ist sie sehr ausgiebig und riecht angenehm.

El mejor sellante del mercado sin duda alguna
