Tubolito: Black is the New Orange

Sure, here is the translated text while retaining the tags and line breaks:```The performance-oriented Tubolito tubes from the eponymous Vienna-based company have stood for the following five characteristics since their invention: ultra-light, extremely compact, twice as robust as classic butyl tubes, fast rolling - and orange. Because of their novelty and innovative nature, the pioneers in the field of TPU bicycle tubes* wanted to visually distinguish their "Tubolitos" from standard butyl rubber products. The choice for the tube and valve stem fell on a bright orange at that time.

However, it happened that style enthusiasts like our 6.8_NoGravel and power posers like NoPain repeatedly had color coordination issues with their frames, jerseys, and helmets, which is why Tubolitos are now alternatively offered to all stylish roadies and gravel bikers with a black valve stem.

* TPU stands for thermoplastic polyurethane; in English: thermoplastic plastic; in Austrian: just made of plastic.

Apart from the new valve stem color variant, there are further changes: From now on, in all road bike/gravel models, the valve cores are permanently glued in place, and Tubolitos with an 80 mm long Presta valve feature one-piece plastic shafts (orange or black) instead of the previously used screwed-on valve extension.

Technical Data: Road/Gravel

* S-Tubo-Road and S-Tubo-CX tubes are only approved for disc brakes
** The two gravel tubes Tubo-CX and S-Tubo-CX are suitable for 700C and 650B

In the coming weeks and months, we will be converting a total of five bikes to the new Road, Gravel, and MTB Tubolitos. These include a road bike each from 6.8_NoGravel and NoPain, as well as NoPain's gravel bike, NoSane's Mondraker MTB, and MOtoman's e-MTB.

(1) S-Tubos are only approved for road bikes with disc brakes and not for rim brakes.
(2) The amount of pressure that can be pumped into Tubolitos depends on the tire being used.
(3) Inflate Tubolitos outside the tire to no more than 0.5 bar, as they can deform and become defective!
(4) Due to the glued-in valve cores, no sealant can be used. Residues of tubeless sealant do not harm Tubolito products.
(5) If a puncture occurs, you can easily patch the tube with the specially developed Tubo-Patch Kit. Note: Puncture repair kits for butyl rubber tubes are not suitable for TPU tubes.
(6) As long as the tire dimensions (wheel diameter and tire width) are the same, Tubolitos can be easily removed and reinstalled in another wheel.

Note: If you carry a Tubolito with SV valve as a spare tube, check in advance whether the valve core is compatible with your CO2 adapter or pump. Occasionally, pump heads with a clamping mechanism do not find an optimal fit.

Sure, here is the translated text while keeping the tags and line breaks intact:```To simplify the lives of mountain bikers - especially mullet riders (29er front, 27.5" rear) - all MTB Tubolitos (Tubo-MTB, S-Tubo-MTB, Tubo-MTB-Plus) received a new medium size and are now suitable for both 29" and 27.5" wheels. This simplifies storage as well as installation, and you always have a spare tube in the right dimension with you.

Additionally, the Austrians gave their lightweight S-Tubo-MTB tubes a firmly glued valve stem, which is supposed to have some practical advantages. However, the fact that the valve stem can no longer be unscrewed also has one or two disadvantages. We have summarized the pros and cons for you.

S-Tubes with fixed valve stem

We handed over two of our MTB-plus tubes to "our neighbor," Mr. EIT, who subjected them to an extensive test over several weeks.
