Caffélatex is a truly innovative tyre sealant, successfully used on and off (mtb, cyclocross) road, for tubeless, tubular and inner-tube applications.
Improved formula (since January 2012): thanks to the addition of microscopic silicate particles, Caffélatex now moves more slowly through holes, allowing the sealing ingredient more time to heal the puncture. These particles are NOT the macro-size (e.g., glitter 150-300 microns) but rather microscopic particles less than 2 microns in diameter. Thus, Caffélatex flow characteristics change on a microscopic level without the headaches of valve-clogging glitter. Puncture repair speed is up to 5 times faster, an improvement especially noticeable with lightweight or thin-casing tires
Foaming action activated by wheel movement: the first advantage of Caffélatex over classic latex-based sealants comes from a foaming agent (Actifoam™), activated by wheel movement. Centrifugal force drives standard latex-based sealants against the outer circumference of the tyre. Caffélatex foaming action causes it to fill the tyre’s entire internal cavity , making it much more effective against sidewall punctures.
Puncture-repairing action: its fast sealing action makes Caffélatex ideal for MTB and road tubeless, tubular and standard tyres. Caffélatex repairs punctures up to 5 mm (mtb) and 3 mm (road).
Stable over time: thanks to its formula, Caffélatex is a very stable and durable sealant, but we know this is highly depending on kind of application and external conditions.
Using the recommended quantities for tyre size, the expected sealant lifespan is:
Tubular: 1-2 years
UST Tubeless tyre: 4-6 months
Tubeless-ready tyre: 2-4 months
Tube-type tyre: 2-3 months
Nevertheless, in the impossibility of knowing our customers’ specific application (kind of wheel/tyre set-up, tyre sidewall thickness and porosities, external temperature and humidity, bicycle storage conditions…), we recommend checking Caffélatex every 2 months, to make sure it’s liquid and therefore retains its ‘puncture preventive’ action. When dry, Caffélatex-sealed wheels are still air-tight, but Caffélatex won’t actively repair punctures.
Not corrosive: being completely ammonia-free, its 100% tyre and rim friendly. It’s also a favourite sealant for cyclocross/tubular applications, creating no harm to the sensitive latex innertubes.
Usage and storage temperatures: from very cold to very hot, exceeding by far those of first-generation latex sealants (usage: -20/+50°C ~ storage: -15/ +30°C).
Recommended quantities: 30 to 50 ml per wheel for road/cyclo-cross applications; 50 ml for mtb tyres up to 26x2.10/29x2.00; 60 to 100 ml for mtb tyres over 26x2.10/29x2.00.

Rated 5 out of 5 by Anonymous best for racing
will not seal as big a hole as it competitors but works far better. 360 protection the moment you start to move as opposed to gravity offerings. Pulled out a nail +-2mm diameter and watched it work today after the hearing click -click-click-click on the commute home. No need to add air and continued. Well impressed.

Got this stuff in 3 bikes, 2 mtb and 1 road. Does exactly what it says on the tin. Sealed punctures on Racing Ralph USTs and Noby NIC USTs in seconds with virtually not loss of pressure. You hear a hiss and you can see some temporary staining on the tyre and that is it.

Rated 1 out of 5 by Anonymous does not work.
do not buy this product as it is ineffective. within half an hour of first use got a very small common or garden thorn, so minor damage to face of tyre and tube, result was puncture with this gunck gushing everywhere. Re inflated x3 but still went down. tube removed and the minor pin prick was repaired with patch. followed the instructions to the letter, will be asking CRC for my money back as I forked out on the 1 letre version.totally useless.

Rated 2 out of 5 by Anonymous This stuff doesn't work
I've tried this with two different wheels. It doesn't work at all- even the smallest pinprick results in the tyre going flat and liquid sealant spraying or dribbling all over the place.
The manufacturer claims that there's a 'new formula' that addresses this, but from the number of recent and similar negative reviews floating around on the net about this product, I really doubt this is true.
I went back to Stans, and have been happy since.
2 stars, because at least it makes seating tubeless easy. 0 stars for actually doing what it is advertised for.

Rated 4 out of 5 by Anonymous A breeze to set up,so far the real deal has been that unlike most of other sealants it did not send my wheel off balance,wich is a big deal actually. Did not puncture my tyres yet anyway.

Rated 5 out of 5 by Anonymous Effective, easy to use
I have been running a tubeless setup for 3 years. I have tried sealants by Hutchinson, Geax and Effeto. The Caffe Latex (CL) is much more fluid than most sealants. This makes it very easy to inject into the tire. I use a syringe to squeeze about 100 ml through the valve stem without having to remove the valve core. In the last 6 months, I have had 3 punctures, 2 of which were sealed by CL. The one which didn't seal was a tear in my rear tire that I got while barreling down some rocky singletrack in the Alps (in hindsight, if I had waited a little longer, it might have sealed but I was impatient to get back on the trail). The other two smaller puncture sealed well but because the stuff is so fluid, when you get a puncture the air pressure tends to cause the sealant to spray out of the hole. In my experience, it may take a minute or two for it to seal and it helps if you rotate the tire so the hole is at the bottom. In fact, the volume of sealant that sprays out and the pressure lost in the tire is quite small but it is alarming when you are rolling along and you see a jet of white liquid coming out of your tire! After sealing, I have continued to use the punctured tires with no issues. In 6 months, the CL sealant has stayed fluid and is still effective unlike the Geax sealant, which worked well as a sealant but dried up after 6 months, and the Hutch product, which didn't work at all for me.
