Review: The Holy Grail of Tubeless Sealant — SILCA Nailed It - I’ve tried pretty much every tubeless sealant out there; Stan’s, Orange Seal, Muc-Off, you name it. But SILCA Ultimate Tubeless Sealant? This stuff is on another level. It’s basically liquid armor for your tires. I ride about 200 miles a week on my Specialized S-Works Venge, and I’ve yet to have a single ride-ending flat since switching to this. You can feel the difference in how fast it seals and how well it holds up over time. It’s thicker than most, which means it actually fills punctures instead of just spraying them all over your downtube like some caffeinated sprinkler system. Just a heads-up, it’s not the friendliest with injectors, but that’s only because it’s loaded with those little carbon fibers that actually make it work. Translation: it clogs cheap injectors because it’s doing its job too well. Do not waste your time or sealant trying to inject it through the valve stem, it just needs to be poured directly into the tire. If you’re serious about your rides and don’t want to pull over to patch flats every other weekend, stop experimenting and get SILCA. It’s slightly more expensive than its competitor brands, but so is losing watts to bad luck.
Review: My new go to sealant - I am comparing this with muck off. This sealant coats the inside of your tire and creates an inner tube. A very thin inner tube. As a result, when you get a puncture it seals very fast. I used it to seal holes that muck off wouldn’t seal. This is very effective. My experience is that for road tires you don’t need the version with the carbon fiber gunk, as it clumps and results in wheel balance issues. But for a mountain bike or gravel bike you do need the carbon fiber because most likely you will get bigger holes. Let’s face it. If you get a large enough hole that the sealant will not fix on a road bike, just use a tube. I don’t trust plugs on a road bike. The tires are too small for them and if you het such a large hole that you need a plug, you probably need a boot. It’s great for thorns, nails, screws, clips. I used 40 ml for road tires and it lasts 6 months. It does tend to clog my valves, and I have to replace them every couple of months. I use 50-60 ml for gravel and mountain tires.

## Features

- Material: SILCA Ultimate Tubeless Sealant uses the power of a foaming latex formula combined with chopped carbon fibers to boost sealing power even at higher pressures.
- Unique Formula: Ultimate Tubeless Sealant contains 5% by volume, 6, 9, and 12mm chopped carbon fibers that have been reclaimed from recycled bicycles, carbon wheels, racecars, and aircraft components.
- Reinforcement: After the puncture is sealed, that area of the tire is left with a zone of carbon fiber-reinforced latex bridging the top and bottom of the hole, helping to reduce the likelihood of future punctures in that area.
- Long Lasting: This superior sealing ability and hole reinforcing ability of the carbon fiber also allows for a higher concentration of anti-freeze agents in the sealant which means more effective sealing.
- Notice: CO2, condensation from compressors, and talc powder can lead to hardening of the sealant. These should be avoided when installing the sealant.

### ⭐⭐⭐⭐⭐ absolutely PAINLESS
*by Y***S on January 6, 2026*

made sure my rim tape was bubble free, secured my valve just finger tight, so as not to hurt my carbon rim, sealant took care of the rest! pumped up 40mm Maxxis Re-Fuse tires with a standard floor pump, no compression tools. second time I set up tubeless with Silca sealant; always works first try. Highly recommended!
