Caffélatex Tire Sealant

I just added some Caffelatex to the 27.5x3 Rocket Ron on the back of my Salsa Mukluk. That tire has between 2,500 and 3,000 miles of dirt two-track in New Mexico. Just for fun I counted the obvious punctures in the tire - 258! 253 of them sealed with Cafelatex (98.8%) while only three required plugging with a Dynaplug. Caffelatex works! Goatheads, Russian Olive thorns, Mesquite spikes and cholla spines - no problem!

A conversion with Caffelatex has always been successful even when we were ready to give up with Stans. Duration over the time is superior with Effetto Mariposa even if much depends on temperatures original porosity etc. but it further increases the economic advantage of its choice.

EFFETTO MARIPOSA CAFFELATEX faces the king STAN’S NOTUBES 4 vs 3 stars Let’s find out the reasons (there are more than one) of such a surprising result The American Stan’s NoTubes deserves credit for having promoted and spread among riders the practice of converting to tubeless tires which were not originally designed in this way. This was possible thanks to a liquid poured inside the tire to automatically seal any possible air losses from punctures or between the rim and the tire bead. However success in converting a standard tire into a tubeless one depends on several factors and excluding rim design this is not guaranteed. For this reason today many different products exist in the market but only Effetto Mariposa with Caffelatex is offering something different from many different aspects. We’ll try and highlight these aspects through a direct comparison. The first one is on price which Effetto Mariposa wins for having its 1000ml product at 1990€ against Stan’s 946ml at € 2990. Characteristics: Stan’s NoTubes has evolved over the years but not as much as Caffelatex with its latest formula from 2012 characterized by added microscopic silicate particles that reduce the outflow from a puncture guaranteeing a repair speed up to 5 times faster and thereby decreasing significantly tire pressure losses. Although most of the rim and tire manufacturers turned a blind eye on the use of a relatively corrosive substance some of them did not approve it but Effetto Mariposa sorted the problem out with its ammonia-free product. This is not the only difference as one of the Caffelatex key features is that it undergoes a deep change when riding. It shifts from a very liquid state to a foam an aspect that on one hand allows it to be easily injected through non-removable valves cores and on the other hand it is far more effective on the sides of the tire. To sum up its original formula allowed the cyclist to keep the cost down and extend the duration over the time (all the sealants tend to dry up progressively) but at the same time it took longer to repair possible punctures compared to NoTubes leadership. Field Testing: Up to now tests were based in laboratories with artificial punctures made in the tires in order to check and compare the sealing time. This procedure did not take into consideration the different nature of Caffelatex which works best when it reaches the foam state meaning when you are really riding the bicycle. Therefore our test was carried out on a usual testing trail puncturing the tire with a punch when stopping and repeating the operation with tools having different diameters from 1 up to 3mm. During this test we repeated the procedure using different standard and tubeless ready tires but always with a certain degree of approximation in the results being impossible to have tires exactly alike and constant casing thickness all along the circumference of the same tire. In the end we can affirm that Caffelatex repairs punctures in the same time as Stan’s but is more effective in the conversion of non-tubeless ready tires even the toughest ones. A conversion [with Caffelatex] has always been successful even when we were ready to give up with Stan’s. Duration over the time is superior with Effetto Mariposa even if much depends on temperatures original porosity etc. but it further increases the economic advantage of its choice. On top of this and considering the non-aggressive Caffelatex formula we are ready to award it winner of this direct comparison despite the absolute Stan’s reliability with tubeless-ready tires.
