Continentalstandard bicycle tube - 26 x 1.4 - 1.75, 40mm Schrader valve

This is a quality product… worth every penny paid.There’s no sense to buy a lesser quality tube.

It worked great

You actually get the product exactly as described by the words,….and not like the picture which incorrectly shows a Presta valve inner tube !!!

Description gives width of 1.25"/1.75"The width is actually 1.4"/1.75" as stated on the box, not the description on Amazon.Probably doesn't matter to most people but I have a specific application for it and needed the width to be 1.25" and expand to 1.75"

I had trouble mounting it snugged to the rim with the nut because the base of the valve stem is too wide. I had to back the nut off, mount the tire, and try to snug the nut up. The base of the stem base now presses on the inside of the tire beads--meaning that the valve is not snug to the rim--resulting in very little stem making it through my double-wall touring rim. I have just enough room to connect the pump with the lock nut installed. That's very solid and has held for a week. We'll see if the tube gets stressed in some odd way and blows out due to it not resting on the rim.

My initial review is that this seems to be very good quality, but I have not ridden it more than a couple of hours so far. It installed easily (Continental Ride Tour City/Trekking Bicycle Tire, 26x1.75), the valve stem seems to be good quality and very long, all metal, not rubber like some tubes. I installed it with the new tires on my old 1980s Fisher Mt. Tam, and was surprised at how smooth and quiet the wheels were. No wobble at all after many years, and a lot of very rocky riding in my younger days in Marin County's many fire roads.

I never thought a tube would make such a difference in the riding experience of a bicycle but these tubes are superb. The moment I started to ride after installing them I immediately noticed a huge difference in the way the bike felt on the road... it felt much more responsive and the feedback I felt from how the ground felt beneath the tires was superb. I was absolutely floored by the difference between what I had to what I have now...i used to just purchase a cheap off the shelf tube that fit... never again. I can't say just yet how they'll perform over time but the immediate difference was so obvious I can't ignore it and will be replacing the tubes in my other bike immediately even though it doesn't need it. It gave my bike a completely different and a much upgraded riding experience... I'm a very satisfied customer for now.

During this COVID Situation, its hard to find inner tube. So This presta valved inner tube was my only chance to fix my tire. I have a 26” mountain bike, which I never rode on the mountain, and originally equipped with scharader(standart) valve. First I doubt this wouldn’t be fitting in my tire, however, it did fit very well. Also, its made by Continental, which is a well-known company for its quality products. Many pumps come with presta valve adapter, but If you don’t have a Presta Valve adapter, I would suggest you to watch videos on YouTube too see how people makes their own adapter.

A diferencia de la cámara que traía la bicicleta (trek 4300) o de las cámaras sencillas, esta cámara se siente diferente, no se siente "dura", se siente como "espuma de pelota" lo que da una mejor sensación al rodar, no creí que hubiera mucha diferencia con las cámaras sencillas pero si la hay. La recomiendo!

excelentes cámaras, muy buen rendimiento y ligereza, muy difíciles de conseguir, pero valen la pena por la espera muy recomendables

Leggera è leggera, non c'è dubbio, pesata sono 136grammi con valvola e tappo. Però solidità zero, è necessario porre tantissima attenzione nel montaggio, basta pizzicarla un minimo ed è da buttare. L'ho usata con gomme antiforatura per circa 500km, e infatti non ho mai forato, è scoppiata la prima volta che ho sgonfiato la ruota per mettere il cerchio sul centraruote.Sconsiglio il prodotto, eccellete prezzo per il peso, ma davvero troppo inaffidabile.

Ho acquistato questo prodotto in tre unità, allettato dal prezzo, per la sostituzione di camere d'aria di bici per uso in località mare per raggiungere la spiaggia o per brevi tratti (insomma niente di performante). Ne ho già utilizzate 2.La prima ha la valvola che non si stringe e non perde aria solo grazie al tappetto in dotazione.La seconda si chiude bene ma perde aria lentamente.La terza non mi aspetto cose ottime.Nel complesso per l'utilizzo che ne devo e ne ho fatto non mi posso lamentare visto il prezzo. Se cercate qualche cosa di più affidabile io eviterei

Purtroppo l’ho resa perché ho sbagliato io modello comunque ottima qualità
