Continental - Inner Tube Tour All 28" Presta 42mm SV - Set of 4

Not a bad buy. Have actually started patching tubes, so hope I don't have to buy as many, but these seem like good tubes for my Pirelli 700x35 Cenurati tires.

Got the tubes for durability and longevity. I got annoyed at pumping tires every day due to thin tubes (stock on bike). Don't care about the increased weight of a couple grams lol. Went from filling air every day to twice a week. Then, added some Stan's sealant into the tube. Now only fill once a week! Also, haven't had any punctures yet. 4 tubes is a the right amount - two on bike, one spare in seat bag. Can take both spares on longer trips. Would recommend for durability and less leakage UPDATE: June, 2023 Tubes still going strong. Put a little more sealant in. Might replace tubes later this year just to have fresh ones in and get all the tire sealant out. Works real well, haven't had any leaks or blowouts in the past several years. Tire exterior is beat up (cuts, couple small punctures, etc) but tube still works! FINAL UPDATE: Checked tube again when rotating tires. Found a large (>0.5 in) clump of old sealant in each tube, so did replace the tubes. The old sealant was still liquid with small chunks in it, but had the large clumps in it.

Quality name brand tubes do make a difference. While quality tubes don't reduce flats (quality tires do), they are much easier to get a good patch job on. I had a Continental Tube with 7 patches on it that was close to 10 years old. Some cheap tubes I had bought were long thrown away. These tubes are more uniform in thickness and molding than inexpensive tubes. The rubber takes a rubber cement and a patch better. While they may cost more than a cheap tube the investment far and away pays back, you will be buying far less tubes. Unless your one of those people who throw a tube away when it gets a puncture.

Would not recommend these tubes in tires inflated above 100 PSI. One of these just exploded in my rear tire this morning after pumping it to 110 PSI. I'm glad it didn't explode while I was riding it!

Durable. Easy to install. Easy to fill with air. Lasts a while. These lasted me a year.

I have a bit of an odd size tire since I ride a hybrid bike, and finding quality inner tubes inexpensively seemed difficult for the particular size I needed. Despite other reviews saying that their tubes popped right away, I have had no such issue. I kept two of these in my bag whenever I rode my bike 14 miles to work every day (then back again). One day, I ran over a metal wire that peirced my factory inner tube. I learned how to install an inner tube myself at work at 1AM using one of these, and it kept on going until the day I bought myself larger tires. I'm not an inner tube expert of any kind (I imagine not many people are...), but these seem thick and sturdy, just as I would expect from a good brand name. I didn't have issues with the valve stem either. All in all, I would buy this again. Although I might not have to because I haven't had one fail on me yet.

Bicycle commuter, I use these tubes exclusively. Others have given me problems with leaks and punctures, these tubes are thick, resilient, and easy to work with. I keep spares at home, at the office and in my bag at all times. These might be a bit more costly than some others on Amazon, but they are worth every penny for the piece of mind alone.

High quality, very reliable, definitely worth the money vs cheaper unknown brands.

Muy buenos materiales, recomendado

Good buy

Although I'm slowly weaning away from tubes, these have always been my go-to replacements.
