Effetto Mariposa Caffelatex Tire Sealant -

Caffelatex Tire Sealant is different than other liquid latex sealants on the market -- it has a foaming agent that effectively creates a tire filling foam as your tire rolls down the road or trail. The advantage is that the Caffelatex foaming sealant can seal the rim/tire junction and sidewall punctures as you ride. For a sidewall puncture, other riders will have to stop and jiggle their tires to allow sealant to flow towards the damaged portion of the tire. But you'll ride right on by as Caffelatex does the job for you.

Caffelatex is a liquid, latex based tire sealant. It's ammonia-free, so it won't harm your tires and rims. It's available in a 1000ml bottle that, depending on your tire size and type, will allow you to install and seal at least ten tires. Caffelatex will seal punctures as big as 6mm in mountain and 3mm in road tires with high pressures.


  • 50ML (1.75 oz.) of CaffeLatex for Mtb tire sizes: 26 x 1.50-2.10, 29 x 1.50-2.00

I used to dread getting goathead thorns in my tires and needing to patch either 5+ holes, since I'd get 5+ goatheads embedded in my tire at a time, or replacing my tube. Thorn resistant tubes didn't work and even DH tubes didn't work. I was ready to convert to tubeless with Stan's, until I found this.
I pumped some of this with the Caffelatex injector into my tubes, which don't have removable valve cores. That's all it took. I've discovered some nice side effects too, such as tire pressures remaining constant despite not riding for days. I also am no longer afraid of going through certain parts of the trail, feeling more inclined to adventure through neglected overgrown trails. When riding to the trail, I ride in the dirt instead of trying to share the pavement with the cars that only give you an extra few inches of extra space when passing.
Now when I see goatheads embedded in my tires, I just smile.
It's not whether this is any better than Stan's or Slime, it's how good it is for certain needs and it seems to handle my needs perfectly. I also mix this stuff with Stan's for my tubeless tires, to help initial sidewall sealing, as I hate spending 10 minutes on the Stan's shake and lay flat on side procedure to create a seal. I rather just put sealant in, pump it up, and ride. I'd go full Caffelatex, but I still had some Stan's and I know Stan's works great at sealing relatively large punctures, while I'm not quite so certain how this stuff will work on any relatively big punctures and don't really want to find out in an inopportune time.

...do not talk about Flats. This is one of those products that I hesitate to give a review on, or even think about, out of a total sense of fear that acknowledging it's use in my wheels might result in an instant flat. That being said - so far, so good in my tubulars. I had two very distinct experiences in installing this sealant though - it absolutely would not move through a set of Topeak extenders that I was trying to use (the extenders eventually COMPLETELY fell apart as a result of having the liquid in them) - a total complete mess. But, I switched to a set of Conti extenders, and the stuff just squirted right in, no problem, as advertised. Good stuff - but I hope I never find out !

I used the Caffelatex Effetto Mariposa to set my sleds up ghetto tubeless and the foaming action helped to get a good seal quickly. So far it has continued to impress. A small puncture on a ride was quickly sealed and barely lost any pressure. No more pinch flats for me.

I race 2-3 times a week and use this sealant to keep me running in cross races. Ive had a few punctures and this stuff seals right up, keeps me going.

Better than stans in my opinion, doesn't ball up, seated super fast, and has held air so far.

This works as well as Stan's but is more of a pain to when it comes to cleaning up. I bought this as I was trying a tire that wasn't compatible with Stan's. The cafe latex sets up and dries much quicker which is good and bad but I wouldn't say it seals any better or worse. I got a large puncture in the tire I was using and the cafe latex sprayed all over my hub, chainstays and chain guide. This dried and was a pain to get off. Furthermore it got all over the back of my calf removing a large amount of hair. All things being equal, I'd choose Stan's which scrubs or wipes off easily as opposed to spending time peeling dried rubber out of nooks and crannies.

I have to remind myself to not drink the stuff. Works just as good as Stan's sealant but I wish it cam with a nozzle or even a small notch in the measuring cup that would help pour more accurately would be nice.
