Caffélatex Tubeless Conversion Kit
To take full advantage of Caffélatex sealant, Effetto Mariposa created the Tubeless Conversion kits, to convert standard bike wheels into tubeless ones.
List of the items in the kit:
- 1 bottle of Caffélatex sealant, 250 ml
- 2 Presta Caffélatex Tubeless Valves with Removable Valve Cores (RVC) (44mm length)
- 1 roll of Caffélatex Tubeless Tape (tape size depends on kit)
- Instruction leaflet
- 1 Portatutto tool bottle
Kit sizes:
EM012 - “S” Kit for rims with external section between 20 and 24 mm
EM013 - “M” Kit for rims with external section between 25 and 29 mm
EM014 - “L” Kit for rims with external section between 30 and 34 mm
The Caffelatex Tubeless Kits have been developed for Tubeless, Tubeless-Ready and TNT (Tube No Tube) and tubeless bike tires, manufactured according to UST standards.
Tire & Wheel Compatibility
Compatible Tire Types
The Caffélatex Tubeless Kit has been developed for Tubeless, Tubeless-Ready, TNT (Tube No Tube) and 2Bliss mountain bike tires, manufactured according to the UST fitting diameter.
Notice: the use of a Caffélatex Tubeless Kit with standard tube-type tires is done under the user's sole responsibility.
External Width of the Rim Section determines Tape Width
Caffelatex Race Tape is for rims with an external section from 22 to 25mm (for example: MavicXC717, XM719, American Classic 350, DT4,1, DT4,2, Notubes Olympic, ZTR355, Arch, FRMXMD333, etc...)
Caffelatex Heavy-Duty Tape is for rims with and external section from 25 to28mm (for example: Mavic EX721, Notubes Flow, etc...)
Kit requires the Rims to be Drilled for Presta Valves
In order to use the kit successfully the wheels / rims must be PRESTA-DRILLED (1/4" valve hole). NO SCHRADER VALVE HOLES (21/64" valve hole).
Tire Size determines Amount of Caffelatex to Use
It depends upon your tire size and brand. We suggest the following amounts of Caffelatex:
| Bike Type | Tire Size | Amount of Caffélatex |
| Road Bikes | all | 25 ml -> 50 ml |
| MTB | 26 x 1.50 through 2.10 | 50 ml |
| MTB | 26 x 2.10 + | 100 ml |
| MTB snow tire | 26 x 3.7 + | 150 ml |
| MTB | 29 x 1.50 through 2.00 | 50 ml |
| MTB | 29 x 2.00 + | 100 ml |
The above figures are some good starting points. Not all tire sizes across all tire brands are created equal. You will need to do some experimentation to find the best amount to use.

Tips for Use
Using the Caffelatex Injector with RVC Presta Valves
Using a RVC (Removable Valve Core) Presta valve is highly recommended. Remove the entire metal fitting from the end of the injector tube. Remove the valve core from the Presta valve. Next slide the tube from the Caffelatex injector directly onto the Presta valve.
Using the Caffelatex Injector with non-RVC Presta Valves
If using a non-RVC (non removable valve core) Presta valve simply attach the metal fitting on the end of the caffelatex injector tube onto the Presta valve.
If you are not removing the valve core mechanism, it is recommended to immediately inflate the tire with a pump after injecting the sealant through the valve. This cleans the valve internals.
Using the Caffelatex Injector with Schrader Valves
This injector also works with Schrader valves. Remove the Presta valve adapter portion of the metal fitting (the first metal piece on the end of the injector tube). Then attach the metal fitting at the end of the Caffelatex injector tube on to the Schrader valve.
It is recommended to immediately inflate the tire with a pump after injecting the sealant through the Schrader valve. This cleans the valve internals.
