Although Iβd prefer a threaded adapter to minimize product leakage while squeezing into fitting, it worked great! Iβve repeatedly gone over a week w/o needing any air added. NOTE: If your climate is HOT, when not riding, keep the bike in the home, especially if your wheels are hookless! In the heat, and not rolling, the prior sealant I had settled to the bottom of the tire, and found myself with a flat. After close examination, no puncture anywhere. Added the Muc-Off, filled the tire, discovered from 6β of white color of the Muc-Off leakage along the tire bead, that the air loss was due to the prior sealer failure. Since in-home storage, almost zero air loss per each week. Great!!

haven’t had a puncture yet but while adding it to a new tire / wheelset I could see that this stuff congeals much quicker than Stans giving me confidence that it will solve punctures and leaks faster. Also worth noting that the new tubeless tire install went smooth as can be with no leaks. Cant say absolutely for sure but perhaps this Muck Off Sealant helped with that. Recommended.

I used all Muc-Off products (besides rims and tires obviously) for my tubeless setup and am very happy!This sealant has held up well and maintained a perfect seal, will definitely continue using this product for years to come!Been using on my commuter with Vittoria Torreno Dry 2.0 700c33c tires.

use it for mtb tyres, ~140cc once every 6mo. the sealant does seal all the many thorns stack into the tyre. the sealant in the bottle stays fresh even after 3 years. doesn’t seal well a bad tubeless sealing tape when air escape from the rim’s spike hole.

The real question is, “Does this product seal punctures?” The answer is, “Yes, with reservations.” During the last couple of months, It has sealed four punctures for me and my riding buddies. All punctures were caused by “wire whiskers” (apparently from worn out automobile steel-belted tires), and thorns (“goat heads”/”puncture weeds”). BUT, it failed to seal a 1/8″ glass cut. Could the cut have been 1/4″? Possibly. In any case, it failed to seal, and after running out of gas cartridges, there is no way to fix the hole (short of inserting a tube), because the sealant requires some pressure to force it into the puncture. Also, the first time you use this product, it isn’t as mess-free as advertised. The learning curve is short, though, and subsequent times are much better. Good news is that spilled sealant cleans up easily with a damp/wet cloth. Incidentally, I now put in 60 ml. of sealant every two months, i.e., twice as often as recommended. I do not bother to remove the sealant still in the tire when I add new fluid. This doesn’t seem to make a difference, and it saves a lot of work.
