Continental MTB 29x1.75-2.5" / 47-622 -> 62-622 Inner Tubes - 42mm Presta Valve (Pack of 2 Tubes)

Good tubes from a reputable company. No complaints here.

This conti tubes are the only ones I can trust. After 5+ tubes that are heavy, and puncture easily, this is the only ones I can ride without overthinking where I am rolling. They stay full for very long periods of time and super thick, stopping any thorns. The stem design is really durable and easy to use. Great overall!

Work like they should

Compré este paquete de cámaras Continental para mi bicicleta de montaña 29” y han funcionado de maravilla. La instalación fue sencilla, el material se siente resistente y de buena calidad, y la válvula Presta de 42 mm tiene el largo adecuado para mis ruedas. Después de varias salidas, mantienen muy bien la presión y no he tenido ningún problema con pinchazos ni fugas. Además, recibir dos cámaras en el paquete ofrece una excelente relación calidad-precio. Definitivamente volvería a comprarlas y las recomiendo a cualquier ciclista que busque confiabilidad y durabilidad.

I have been using these tubes on my mountain bike for a while, it really frustrates me that some of them are really solid, and some of them are crap. Like the one I show here in the picture has the stem ripped off almost entirely. Make sure you test them before put them on.

I have been using these for a while and no issues. Quality if great and value also. It fits perfect every time. Just make sure when you install them just add a bit of air to the tube so it wont get twisted.

I’m extremely disappointed with the quality of the inter tubes from Continental. I took a half day off work—unpaid—just to get outside and enjoy a new park. About 15 minutes into my ride, I noticed the rear tire pressure dropping, even though I had checked PSI before starting. I stopped, aired it back up, and within 10 minutes it was low again. I replaced the tube with a spare and immediately saw the issue—the presta valve had separated from the tube itself. After installing a second tube, I got about 45 minutes of riding in before the exact same failure happened again. Once more, the presta valve had detached from the tube. At that point, I had gone through multiple tubes, all failing in the same way. What should have been a relaxing day outdoors turned into a complete waste of time, money, and effort—lost wages, fuel, and a ruined ride. This isn’t normal wear and tear—this is a clear quality issue. I expect better reliability, especially from a brand with Continental’s reputation.

Spare Continental 29”x2.40 Tube for bike rides!

Solid tube…. for the price, I would definitely recommend.
