About NomOusse

Tubeless off-road solution

System composed of a small tire and its tube, which are fitted on the rim, inside the off-road tire. NomOusse fulfils three functions:

  • 1-Sealing: The outside of the nomOusse, inflated at 4 to 6 bar, seals against the inside of the off-road tire, generating an air chamber for the off-road. This chamber is watertight to the rim and can be inflated to the pressure that the user requires.
  • 2-Locks: The inner nomOusse tire, inflated between 4 to 6 bar, produces a force of 1500 kg against the inside of the off-road tire and locks it to the rim, avoiding any displacement.
  • 3 –Protection: NomOusse, in addition, exceeds by 3 cm the rim diameter. It is the only tubeless system on the market that provides an efficient rim protection against impacts and acts as emergency rolling support, even in flat conditions.

What is Tubeless for enduro?

Literally without a tube, tire without inner bladder.

In the past, all wheels were made of spokes and all tires had a tube. Later arrived the solid sheet metal rims and the tubeless tires.

These have a smooth edge that seals against the rim, with the help of mounting paste. Its use has been adopted for its simplified assembly and being safer. On off-road motorcycles, the use of tubeless tires collides with two drawbacks:

1-The impacts against stones and the sport usage require the use of light and very resistant wheels. This is only provided by spoke rims.

2-Tire locking. To ensure grip, one needs tire pressures between 0.8 and 0.3 that do not ensure the tire is locked to the rim.

Both issues 1) and 2) enforce the use of tubes and rim locks as the usual option.

ASSEMBLY

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

SIMPLY & ROBUST DESIGN

Engineered with simple and stiff elements.

HOW IT WORKS

When inflating nomOusse to 60 to 90 psi -4 to 6 bar-, it presses against the off-road tire inner edge in a 10mm wide surface, with a force equivalent to 3,300 lbs -1500 kg-. This produces the sealing between both and a firm fastening locking of the off-road tire to the rim. And it acts as a barrier against rim impacts and as emergency rolling support.

SAFER 
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 rim lock has been removed, being this the weakest point of other systems. In 2,000 miles, the wheel spins around 1 million times and the chances of hitting the rim lock and breaking it are higher.

THE LIGHTEST 
0.55 lbs. weight reduction compared to a reinforced tube + rim lock, 0.31 lbs. if the tube is standard. Compared to Mousse + rim lock, 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.  

MORE FLEXIBLE 
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. 

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

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

NO RIM LOCK
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 -60 to 90 psi -4 to 6 bar is recommended-. As a reference, trail motorbikes run at 1.7 bar without rim lock, 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.

NO NEED TO DRILL THE RIM
Rim lock 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.

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

RIM PROTECTION
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 aluminium powder). In addition, nomOusse protrudes 1,2 in – 3 cm- over the rim edges all around, thanks to the absence of a rim lock, 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

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.

ASSEMBLY OF THE NOMOUSSE (FOR OFFROAD USE ONLY) A CORRECT ASSEMBLY IS SATISFACTION GUARANTEE, STEPS:

It must be clean and without any internal projection that could puncture the tube. The rim must have the spoke protection tape in good condition to protect the tube. A tape 28mm wide and 0.8mm thick is fine. Mount it so that it fits well without being too tight. The system does not need a tire lock.

The system has two valves, one for the inner tube and the other for the offroad. Each one should come out through a hole in the rim. Put the camera of the nomOusse inside the nomOusse, partially and a little air to the camera so that it takes off. Put the valves in the holes in the rim and secure with a few turns of the cap. Put the rest of the camera into the nomOusse tire. Lubricate the edges of the nomOusse with mounting paste and insert the entire nomOusse and its tube at the same time into the rim, by hand, advancing from the valves, without crushing the tube and without pulling the valves. The part of the nomOusse that goes into the rim should be moved to the central part of the throat, with a smaller diameter, to facilitate mounting. If necessary, help with a flat lever, spoon type. Inflate slightly -1 Bar- and check that the nomOusse and its valves fit well on the rim. Lubricate the entire blue tire well, including both sides. This facilitates assembly and sealing.

The tire must be clean. Check the internal flanks well and remove any foreign element that could make it difficult to seal.

The rim with the nomOusse mounted, inflated to 1 Bar, must be placed inside the offroad tire. Lubricate well the inner sides and edges of the tire. Press against the ground so that the offroad remains oval by opening the tire. On very hard tires, such as Desert, it may be useful to use a sling, on one side. Press the rim against the tire to place it inside, better helping with a lever on the other hand. Release the pressure from the nomOusse. Put the tire on the rim on one side and then on the other, STARTING FROM THE OPPOSITE PART OF THE VALVES, WITH THE HELP OF A PRESSION LEVER, AND FINISHING, AVOIDING ALL SIDE PRESSURE ON THE VALVES SO AS NOT TO DAMAGE THEM. The valves must be in a natural position, without forcing.

 

As everything is well lubricated, everything must be in place, otherwise, move slightly until the valve of the nomOusse tube is in position. Tighten the valve nut by hand, lubricating the thread so it does not seize. Inflate the nomOusse up to 4 Bar. With 2 Bar in the nomOusse it is enough to bead the offroad tire and hold it firmly around the entire contour of the rim. Check the beading and that the position of the pipe valve is correct. The ring that forms the “nomOusse” should center naturally with the one formed by the offroad and the rim. If after inflating the nomOusse and heel the offroad it is appreciated that the rubberized valve is not well positioned towards the outside, deflate by removing the valve core and make the wheel bounce against the ground, with the valves up and without breaking the offroad bead. Inflate again. The recommended pressures are between 4 and 6 Bar for normal or extreme use respectively. Remember that the sealing is done by pressure. If we put more pressure on the offroad, we must keep a minimum difference with the nomOusse of 3.5 bar.

Before inflating the offroad, remove the inner part of the valve and put 150 cc of water-based anti-puncture gel – so that it can be cleaned – even bath gel is a good substitute. This gel is used to cover any pores, avoid wear of the nomOusse and damage from dry impacts against the offroad. As long as pressure is maintained on the nomOuse, the offroad tire will be firmly attached to the rim and sealing its edge. Even if it loses all its pressure, it can still roll reasonably well, without the typical jumps that occur with the tire lock that only holds at one point. The offroad use pressure depends on the type of tire and the user’s preference. Even with medium / soft tires, it is frequently used between 0.4 and 0.5 bar, reaching down to 0.2 bar, sometimes and always with gel inside the offroad.

1st Remove the core from the nomOusse tube, remove the valve nut by hand, without forcing it so as not to cut the throat, and push both valves inside so that they remain loose. Break the bead on the opposite side to the valves, without pressing on them. Apply assembly lubricant all over the edge of the offroad and ONLY remove the tire starting with the valve area, without taking the nomOusse out, it remains on the rim. 4th Repeat the same on the other side. Press both -rim with nomOusse- to the bottom of the offroad tire and remove by pulling the rim from the side. Clean everything well, lubricate . The assembly will be done in reverse order.

A.- CARE OF THE NOMOUSSE PRO: You do not need any except those already mentioned, disassemble carefully so as not to damage it, make a clean and well lubricated assembly. Keep the pressure between 4 Bar and 6 Bar. This way it can be reused many times.

B.- THE NOMOUSSE LOSES PRESSURE: It could be the valve core lose or the tube. If the tube, it must be disassembled and replaced, checking that there is no skewer or protrusion on the rim or nomOusse. You can  try before with anti-puncture gel. Below 4 Bar its operation is not guaranteed.

C.- THE OFFROAD TIRE HAS A LIGHT LEAK: If the mounting guidelines have been followed, the pressure loss in one week will be less than 0.2 Bar. If it is higher, it may be due to a slight puncture or a defective seal. Take into account that the length to be sealed is 3 meters and the internal surface of the offroad is usually not smooth. Check by putting the wheel in water in sections.

If the air comes out through the spokes, or the contour of the valves, there is a leak between the offroad and the nomOusse due to dirt, foreign body or lack of gel. It should be disassembled, cleaned and assembled according to the instructions. Check that the conduit and its valve have no leaks.

If a puncture is found, remove the puncture, deflate and seal by inserting cyanoacrylate into the hole or repair with tubless type puncture kit repair.

D.- THICK PUNCTURE IN OFFROAD TIRE: You can drive without pressure, with caution. Repair with a kit for tubeless wick type punctures. If it was too thick it might need a patch on the inside of the offroad.

E.- TIRE + NOMOUSSE PUNCTURE: It is difficult but in the field everything is possible. When we puncture the nomOusse we lose the tire lock, the tire does not hold on the rim, it turns and can come off. With 5 m of 4 mm polyamide rope -60 gr in weight-, wrapping the tire and rim tightly, every three spokes, we can move slowly. In any case, this rope is a very useful safety element in enduro.
