Still using inner tube unable to lower pressure or mousse, unable to adjust hardness?
The best grip and high security in any situation​


*This new off-road “tubeless” system, has been designed by two engineers and enduro riders*

“The main problem we have in enduro is to pinch the inner tube, having to interrupt our day of fun. After testing every solution on the market, we were not satisfied. Thus, we decided to develop our own system. After several tests, we realized that we had found the perfect solution. ” NomOusse fastens the tire all over the rim. NomOusse acts as a barrier against rim impacts. Also, NomOusse acts as an emergency support when the main tire pinches and allows the rider to drive to a safe location.

About NomOusse

NomOusse, what is it? Tubeless offroad solution

What is NomOusse?
NomOusse, why use it? It´s a great tubeless offroad solution
It is a system composed of a small tire and its tube, which are fittted on the rim, inside the offroad tire.
NomOusse fulfills three functions:

  • 1- The outside of the nomOusse seals against the inside of the offroad, generating an air chamber for the operation of the offroad. This chamber is tight to the rim and can be inflated to the pressure that the user requires.
  • 2- The internal nomOusse tire is inflated at a pressure between 4 to 6 bar. This presses strongly against the inside of the offroad which produces the seal indicated in 1) and lock the offroad tire to the rim, avoiding any displacement.
  • 3 – NomOusse, in addition, so that it exceeds the diameter of the rim, is the only tubelization system on the market that provides an efficient rim protection against impacts and a emergency rolling support.

What is Tubeless for enduro? - Meaning

The literal translation is without a tube, which in the case of tires would be without inner bladder.

In the past, all wheels were made of spokes and all tires had a tube. Later on arrived the solid sheet metal or aluminum alloy wheels and consequently the tubeless tires. These have a smooth edge that fits and seals against the rim, with the help of mounting paste. They also carry, internally, a layer of non-porous rubber to retain air. Its use has been widespread in road vehicles by simplifying assembly and being safer. On off-road motorcycles, the use of tubeless tires collides with two drawbacks:
1) The impacts of the wheels against stones and the sports use itself, require the use of light and very resistant wheels. This is only provided by spoke rims.
2) The needs of the use, mainly the grip on the ground, force the use of tire pressures between 0.8 and 0.3 bar. These low pressures do not ensure the tire is fixed to the rim. This is done using screwed fitting systems that hold the tire and prevent its displacement. Both issues 1) and 2) make the rim not air tight and force the use of tubes as a usual option.

Off Road Tubeless System


nomOusse makes the difference. Why? It is all about advantages


We explain step by step how to install you nomOusse for you to enjoy it.


Engineered with simple and stiff elements.


When inflating nomOusse to 60 psi, it presses against the off-road tire inner edge in a 10mm wide surface, with a force equivalent to 3,300 lbs. This produces the sealing between both and a firm fastening of the off-road tire to the rim. And it acts as a barrier against rim impacts and as emergency rolling support.

This produces the sealing between both and a firm fastening of the off-road tire to the rim. And it acts as a barrier against rim impacts and as emergency rolling support.

Being tubeless, there is no chance for pinching the inner tube. This allows to ride with less pressure in the tire. Less pressure means more contact surface and less wear. A flat tire is easily repaired with a tubeless repair kit. The lock ring has been removed, being this the weakest point of other systems. In 2,200 miles, the wheel spins around 1 million times and the chances of hitting the lock ring and breaking it are higher.

0.55 lbs. weight reduction compared to a reinforced tube + lock ring, 0.31 lbs. if the tube is standard. Compared to Mousse + lock ring, weight reduction is around 1.9 lbs. in 18 ” wheels. Moreover, being this load reduction at end of the swingarm, it results in a considerable improvement of the suspension performance.  

Tire surface can easily bend to better adapt to the terrain. Maximum adaptation. The “touch” improves over the use of an inner tube, even higher when compared to Mousses.  


The lower pressure (1), lightness (2) and flexibility (3) result in a very remarkable increase in traction. Also in less rebounds and more ride comfort. Pressure is adjusted to your needs.

The nomOusse system is simple and its price is lower than Mousse or other systems. Is reusable many times without degradation, and it increases the lifespan of the tire.

Between rim and off-road tire there are no other elements than the nomOusse and its inner tube. Nothing hinders the perfect fit. The fastening of the tire to the rim is safe and tight all over the wheel, even from 29 psi pressure -50 to 58 psi is recommended-. As a reference, trail motorbikes run at 1.7 bar without lock ring, despite having much more weight and torque. Even with zero pressure in the off-road tire, rolling is continuous, nomOusse works as emergency rolling support. Typical bounces when a standard tire is pinched do not occur and the rim is not damaged.

Lock ring hole is used for the second valve. In addition, rim is kept clean and mud-free inside, thanks to the perfect sealing against the tire.

Wheel grips more and scratches less. nomOusse Reduces the amount of rubber, and it is Reusable and Recyclable -the three R’s of ecology-.

nomOusse firmly fastens the tire preventing it from displacing inside the rim, and thus preventing rim abrasion produced by dust or mud (with the typical color of aluminum powder). In addition, nomOusse protrudes 0.8 in over the rim edges all around, thanks to the absence of a lock ring, absorbing shocks against steps or sharp edges, protecting the rim and the inflation valve from being hit. Spokes nuts are kept fastened longer.


NomOusse Installation in 7 easy steps. Here you have the nomOusse Tubeless Installation Instructions document. We have even made a video tutorial for you. A proper installation is satisfaction guarantee.


It must be clean and without any inner embossment that can puncture the tube. Rim must wear ONLY the strip and it must be in good condition, if not, replace it with a new one. A tape of 1,1 in wide and 0.03 in thick is fine. Mount so that it fits well without being too tight (Fig. 1). The system does not use a rim lock. 

WE RECOMMEND PLACE THE DUCT NOMOUSSE SIDE ON THE BRAKE RIM SIDE, AS REFERENCE. System has two valves. Each one will exit trough a rim hole. Install the NoMousse inner tube inside NoMousse, partially (fig. 2), and some air just de wrap tube. RUBBER AND METAL RINGS GO INSIDE RIM AND INSIDE THE NOMOUSSE SO THAT THE EXTERNAL
EDGE OF THIS CAN SEAL AGAINST THE OFFROAD. OUT OF THE RIM ONLY BOTH NUTS AND THE BLUE SOCKET. Put valves through rim holes and secure it with a few nut turns (fig. 3). Put the all NoMousse tube inside his tire. Lightly lubricate NoMousse edges with tire mounting paste, then place into the rim, by hand, starting from valves, both NoMousse and his tube at once, without crushing the inner tube. While NoMousse is being placed inside the rim, make sure it gets allocated in the central part of the rim, also called throat, in order to ease assembly (fig. 4.1, 2 and 3). If necessary, use a tire lever, flat type, NOT FORZING tire edge. Inflate slightly -3 psi- and generously lubricate both sides of NoMousse (fig. 5) so it adapts well to the inner side of the off-road tire.

Tire must be clean. Check both internal sides and remove any foreign element, to not disturb sealing.

Rim with NoMousse previously mounted, inflated at 3 psi (fig.  6), must be put into off-road tire. Lubricate well internal flanks and tire edges (fig. 7). Press against the floor making the tire to open (fig. 8). Press the rim against the tire to place it inside (fig. 9), better helping with a tire lever from the other side. Release all the pressure in the NoMousse. Mount the tire on the rim on one side and then the other, LOOKING NOT TO PUSH INSIDE IN THE NOMOUSSE CONDUCT ZONE TO DONT FORCE IT. Valves must be in natural position, unforced. 

As everything is well lubricated, everything must be in place. If not, move it slightly until the NoMousse tube valve is in the correct position. Tighten both nuts by hand. Inflate the NoMousse to 50 psi. Already 30 psi is enough to bead the off-road tire and firmly hold the entire contour of the tire. Keeping NoMouse at 50 to 58 psi will give us enough safety margin. Verify that beading is perfect.

 Inflate off road to desired pressure ALWAYS GENTLY -if compressor is used-. AN INTERNAL PRESSURE IN THE CONDUCT, EXCEEDING THE PRESSURE AT NOMOUSSE TUBE – usually 58 psi – CAN uncouple the joints. While pressure is maintained in the NoMousse, off-road tire will always be firmly beaded to rim, making a perfect sealing. Rolling with offroad pressure below 5,8 / 7,2 psi, can wear it by continuous friction, if using soft body tire. 

Deflate NoMousse. Unbead without pressing at NoMousse ducting area, to don’t damage it. Be very careful to extract, ONLY, off-road tire from one side and then the other, without damaging NoMousse with tire levers. NOMOUSSE IS REINFORCED BUT CAN BE DAMAGED IF HOOKS WITH TIRE LEVERS WHEN REMOVING OFF-ROAD TIRE. Rim with NoMousse remain in between. Press both to the bottom of the off-road tire and remove them pulling the rim from the side. Clean everything well, lubricate and start at point 3. 

A.- NOMOUSSE CARE: None need except those mentioned above, dismantle carefully, make a clean and well lubricated assembly. Keep pressure above 50 psi without exceeding 73 psi. It can be reused many times. 
B.- NOMOUSSE LOSES PRESSURE: Remove it and replace NoMousse inner tube, checking that there is no spike in the rim or inside the NoMousse. You can also try before with anti-puncture foam. Below 40 psi operation is not guaranteed.
C.- OFF-ROAD TIRE SLIGHTLY LOSES PRESSURE: If you have followed the mounting guidelines pressure loss after one week will be less than 3 psi. If it is higher, may be due to slight puncture or a faulty installation. Take into account that the length to be sealed is 120 in and the internal surface of the offroad is not usually smooth. Check the wheel by putting it in water (by sections). 
If air comes out the spokes, or around valves, it means that there is leakage between the off-road tire and NoMousse due to dirt or lack of assembly paste. It would need to be disassembled, cleaned and assembled according to the instructions. If there is a puncture, remove the spike, deflate and seal introducing cyanoacrylate in the hole or repair using a tubeless repairing kit. You can also try to seal with 0,026 to 0,04 gal of thick waterbased gel -shower gel works-, inside off road, removing valve core (Fig 10). After some turns, gel tends to clog small leaks and also works as internal lubricant. It can be used preventively. Montaje NoMousse Rev. Dec/17 5
D.- THICK PUNCTURE IN OFF-ROAD TIRE: You can ride without pressure, with caution. Repair using a tubeless repairing kit. If it was too thick you may also need a patch inside offroad tire.
E.- PUNCTURE PREVENTION: You can use foam sold for this use. It will clog possible punctures. It must be water-based, without adhesive component, which would require replacing the NoMousse when replacing off-road tire. The use of gel with solid particles can obstruct the inflation duct -0,1 in diameter – if it is allowed to exit through the duct and solidify.
F.- PUNCTURE OF TIRE + NOMOUSSE: It’s extremely unlikely to happen but at off-road, everything is possible. By puncturing NoMousse, tire has no bead to rim, and it can get away. With a 200 in long & 0,12 in thick polyamide rope – 1,2 oz weight-, strongly rolled the tire and rim, every three spokes, we can drive slowly.
