Must have for tubeless

I’ve used this in my tubeless road bike tires for years and always had good luck with it sealing up.This spring, I tried it on my lawnmower you’re that was leaking and it sealed right up and hasn’t leaked since. Highly recommend this!

The product description does not match what is written on the bottle. I used these on my road bike DT Swiss with conti gp5000 s tr based on the description that it could be used for road tires with 30mL and up to 120psi. However the bottle only says it works for up to 80psi. There may be some truth to this claim as one of my tires holds pressure around 80psi but the other typically loses pressure overnight if inflated to around 90. It looks like muc-off now makes a road and gravel specific sealant. I may try that next time, though I have a lot of sealant remaining from the liter bottle and not sure what to do with it! I have not had a puncture yet so not sure how well it will work, but the set up was easy.

I started off using Orange Seal, but Muc-Off definitely provides better performance. In testing it seems to outperform everything else with the exception of Silca, which will seal 7mm+ punctures, though at a higher cost. Here’s my advice: If you ride in an area that has plenty of cell phone coverage, you’ll rarely have a puncture that Muc-Off can’t handle. This is especially true for road riding. If, however, you are off road (gravel or MTB) in areas that don’t see that much traffic, and that have spotty or no cell coverage, spend the extra $$$ and go for the Silca. I’ve been doing just that on the gravel bike, so I’m switching to Silca for the gravel bike, but sticking with Muc-Off for the road bike and mountain bike (everywhere I ride on the MTB is local with good mobile coverage… The gravel bike though… That thing gets me to places where I’m unlikely to see another person in a 24 hour period if I were to just stop).

I've had at least two punctures that I know of since switching from tubes to Muc-Off Tubeless Sealant. First was a roofing tack that went straight into my tire. I pulled it out, sealant bubbled from the hole for about a second, and then it stopped. Didn't lose any tire pressure, and the seal held.Second was a small gash in the sidewall right near the rim. Now this one didn't seal up on its own, but the sealant did reduce the amount of air escape so I didn't have a sudden catastrophic loss of pressure. It took two bacon strips to plug the hole, and then it sealed and surprisingly held for several weeks before the bacon strips popped loose, and I just replaced the tire. To be fair, that's a tough situation for any sealant to deal with, so I'm impressed with how well Muc-Off performed.Other things I like: the bright pink color stands out and is easy to see if you're hunting for a leak, it remains liquid in the tire for a long time, it smells like a fruit smoothie, and it washes away with plain water.

This stuff is just awesome💯💯 works in just seconds after applying and filling the tire. If you used anything besides muc off tire sealant you must clean the old stuff out! On the other hand muc off was the only tire sealant I used.. so there was no cleaning. I rode about 5 months with no issues. And then bam tire was completely flat which was my fault.. 5 months with no issues.. I didn't do the routine check up that it explained on the bottle.. my fault.. but.. I followed the same instructions when I applied this the first time around the.. and bam! Sealed it up just like the first time.. this stuff is awesome 💯💯 it does get a bit messy so have some rags handy to wipe things off.
