Tannus Tubeless Rim Protector for tubeless tire (MTB/Gravel)

29″x 2.1″ - 2.6″ (PRO) weighs only 155 grams

27.5″x 2.1″ - 2.6″ (PRO) weighs only 140 grams

700 x 33-47 (CLASSIC) weighs only 70 grams

700x(33-45C) & 29"x(1.95 - 2.10) (LITE) weights only 50 grams

27.5”x (1.95 - 2.10) (LITE) weights only 50 grams

700 x (28 - 32C) (LITE) weights only 45 grams

To give you an idea, an inner tube weighs between 160 and 190 grams, so it is lighter than most inner tubes.

Additionally, the Aither compound of the Tannus Tubeless does NOT absorb sealant so the lightness of the insert is always maintained.

Protects your RIM from impacts and dampens ground vibrations.

It is Ultralight and improves your PERFORMANCE. Thanks to its design, it reduces rolling resistance by 3%.*

Improves TRACTION in corners thanks to its sidewall support.

NO sealant absorption thanks to its Aither material, maintaining the lightness of the insert and eliminating future maintenance.

RIDE FLAT capability: Allows you to ride at (10 km/h) while protecting the tire in case of a puncture.

MODULAR design: The perfect balance between rim protection, lightness and comfort.

*Validated in laboratory tests and by our professional team

Tannus Tubeless stands out from the rest of the tire inserts thanks to: 

• Material

• Thanks to the Aither technology, our insert is VERY STRONG while ULTRALIGHT and DOES NOT ABSORB SEALANT.

• Design and Features

• The PRO and LITE designs are engineered to IMPROVE performance, such as cornering traction, rolling resistance and ride feel.

• Modularity

• Most inserts offer only a single solution for many riding styles / disciplines.

• The modular system has been designed so that you can choose the level of protection you want to match your type of riding and needs.

• On smooth rides or in races, you can reduce the weight to get the best performance while keeping rim protection and on the most extreme rides and disciplines (DH, Enduro), combine the Tannus LITE & PRO thanks to their rib design for maximum protection.

Tannus Tubeless is made from a patent material called Aither. It is a high-quality foam-like polymer that offers vibration damping, a smoother ride and resistance to punctures.

Compound enhancements for Tannus Tubeless:

• STRONGER (20mm protection)
• LIGHTER (50% + than the Armour for inner tubes)
• DOES NOT ABSORB SEALANT LIQUID

Thanks to the shape of the Tannus Tubeless, it has been possible to improve rolling resistance.

When using it, it goes 3% faster than without using a mousse / insert.

As the tire is compressed while pedaling, the tire has a rebound property. This bouncing property 'propels' the bike forward.

The Tannus Tubeless adds an additional rebound element that adds to the propulsion of a standard tire, making pedaling even faster.

The sealant must be "Tubeless Specific".

The recommended amount of sealant for proper operation is between 118 ml and 177 ml per tire.

Recomendations:

• If you've made some sealant in your garage, we can't guarantee anything, but props to you for trying.
• Also, don't use any "tube" sealants IE Slime, Flat Attack etc.

It is to allow the sealant reach the outside of the tire, as we don't want the sealant to stay “stuck” on one side of the tire.

We want the sealant to flow inside of the tire when is spinning around. The holes are there to let it flow.

This way there will always be enough sealant to seal punctures.

It does not affect the mounting, however one of the mounting techniques is that if you are going to place the sealant after installing the Tannus Tubeless and tire, it is to try to align one of the holes where the valve is to apply it directly to the rim.

Nope! Any tubeless valve will get the job done.

This is made possible by the flexible wings that create two chambers within the system. You can put the sealant in, and the holes in the insert allow the sealant to pass through without getting stuck on one side of the insert.

Most mousse come with a specific valve, they allow air to enter sideways since the mousse itself covers the upper part of the valve. With Tannus Tubeless they are not necessary and you can use of your current valves.

When we combine LITE & PRO to form the FUSION, the sealant can continue flowing through the rib design of Tannus

To install the Tannus Tubeless it is only necessary that the rim is Tubeless.

Make sure that you tape them well, a poorly taped tubeless system has more flat issues than anything else out there.
