Portal 700×28 Tire 100% Puncture-Proof (Road)

Tannus tires are solid tires, but not rigid. The Aither compound is formed by millions of closed air micro bubbles, which allows us to establish a certain air pressure (simulating the inflation pressure), giving elasticity, better performance and comfort to the compound.

In the road models we have available 2 hardnesses (Hard and Regular) and you must choose according to the use and weight.

We recommend the Hard hardness (high inflation pressure) for users weighing more than 80kg or for those who want to obtain better performance - lower rolling resistance.

We recommend the Regular hardness (medium inflation pressure) for users weighing less than 80kg or for those users who want more comfort.

You can see the pressure equivalence in every Tannus model description.

Tannus tires have two main benefits over a traditional tire:

• 100% Puncture-proof
• No maintenance

All this thanks to the Aither compound:

• It does not suffer degradation over time.
• It does not suffer from cold contraction, heat expansion or is affected by UV rays.
• It can operate in a very wide range of temperatures: from -20º to 60º.
• The mixture of copolymers, united and put together in a single body, provides strength, stability, elasticity, grip, lightness and long life.
• Formed by closed air microcells, it allows us to define the equivalent inflation pressures on the wheels, REGULAR or HARD.
• It is estimated that the material can reach up to 10 years of useful life.

The Tannus tires are compatible with most rims on the market, including carbon or profiled rims, excluding tubular rims. It is necessary for the rim to be Clincher or Tubeless Ready, which incorporate the 'hook' that allows the pin to be secured.

The key aspect to check the compatibility is the inner rim width, there are 2 ways to check:

• Look on the rim (not the tire) the numbering called ETRTO. It is usually engraved or in a sticker on the side of the rim, 622- (inner width in mm)
• Measure the inside width of the rim with a caliper.

Each Tannus model has a range of compatibility.

Check the compatibility table to choose the right model.

All Tannus models thanks to the Aither compound guarantee a good grip both in dry and wet.

At first glance, by the appearance of the Tannus it may seem the opposite, since they have a light layer of lacquer that makes it shiny, however, when riding between the first 50 - 150 km it disappears and you can really see the texture provided by the great grip.

Professional users highlight the grip as the second strong point of the Tannus, followed by the anti-puncture aspect.

Thanks to the benefits of the Aither compound, 6,000 km of use are guaranteed in perfect conditions.

However, the useful life of the Tannus can exceed 10,000 km;

From those 6,000 or 8,000 km, the wear is only perceived because the surface is flattened, therefore it will not maintain an optimal shape for a good cornering at high speed, but it will be in very good condition, for example for a daily journey not focused on sports cycling.

The compound Aither has the following characteristics, among others:

• It does not suffer degradation over time.
• It does not crack.
• It can operate in a very wide range of temperatures: from -20º to 60º.
• It is estimated that the material can reach up to 10 years of useful life.

All Tannus references can support a weight of 150 Kg (75 Kg per wheel).

This aspect is really positive for cycle travelers and cargo bike trailers.

Tannus are a great roller option. The main advantages over other tires are the following:

• Avoid punctures and inner tubes blowouts

Remains that remain embedded in the tire when we pedal outside, cause a puncture due to the friction with the roller.

Tires tend to get very hot on the roller and by extension the inner tube, which leads to a blowout.

If the rim tape breaks, the tube is pinched with the hole of the spokes, causing a puncture.

With Tannus we avoid all these problems.

• Great durability, always ready and multipurpose

The Tannus have a great durability and useful life, we guarantee +6,000 km. In addition, another important factor is that your bike will always be ready to use on a roller and outdoors, you will not have to change tires for each use.

We recommend removing the Tannus from the roller once we finish using it, so it does not take any deformation while it cools down resting on the roller. In the event that it occurs, just by pedaling again on the roller for 5 min it gets fixed.

Each Tannus includes everything necessary for its assembly:

• 3 sizes of Pins.
• Assembly tool.
• Assembly instructions.

Tannus airless tires have been a great innovation for the cycling world, not only when it comes to efficiency against punctures but also for the long durability of its use and the reduction of waste that it entails.

«Using 1 Tannus tire is the equivalent of using 3 traditional tires and 8 inner tubes.»

The aspects that make Tannus ECO Friendly can be summarized in three main points:

• Minimization of tire and inner tube waste
• More efficient production process and less harmful materials: no need for textiles, filaments, steels, metals, such as the production of valves, rim bottoms, sealants...
• 100% Recyclable: (Second life in applications in the footwear industry and playgrounds)
