🚲 Continental MTB Bicycle Tubes - 26, 27.5, 28, 29 (1.75-2.25) with Presta Valve 42mm - Value Bundle of 5 Bike Tubes Review

Completely defective. Within a week I used 3/5 of the tubes in the pack and all three were leaking at the seams. Extremely annoying how many times I had to swap tubes and the last mistake on a track was in the middle of nowhere (my mistake for believing that one of the 5 was legal). This is probably the worst Revain order I've ever placed.

It's all still in the box. In my opinion, this is where the tube should be. I had a streak of bad luck during the week and used up both of my spares that I carry in my backpack. So I had to get some more and these 5 packs fit the bill. Conti is a great brand, I'll write something more meaningful if I ever go through this pack and need a refill.

I was so happy to receive them in the mail. After installing new tires and tubes, I pumped them up to 35 pounds just to see how they would look. Both hoses I used had slow leaks that needed patching. I didn't even play around with them and just used the other two I got instead. These two worked well. The desire to give the last blunt in order in favor of the doubt still leaves me with 3/5 working pipes.

I bought these for a removable valve core so they can be used with Stans Sealant. So one star for the swap core. The reliability of the pipes is only average. What's not just average are the FUNNY long valve stems - actually 2 inches protruding from the rim. I've seen a description that says 42mm but it all depends on how it's measured as to what you can actually get. What I received was a SCREW BARREL. Incredibly long, making them prone to breaking while riding. Continental, why be so stupid…

on the rear of my Diamondback Foil 29er with Weinmann SL7 rims, Continental (Trail King 2.2) tires, Velox rim tape and Mr. Tuffy. I keep it around 35-40psi and they seem to be bursting at the seams. I tried higher pressure, which seemed to be an even bigger problem. I ride the relatively flat trails of Southern California; a mixture of gravel, usually dry mud, and sand. I have the same tube up front which doesn't break that often (although I did have a few spike punctures) so the issue must be…

These hoses would be good if it weren't for the fact that the valve cores unscrew too easily. If you are using a screw-on type portable pump (meaning the pump hose is screwed onto the valve), when you inflate the tire (after replacing the ruptured hose) and unscrew the pump hose from the valve stem, the valve core comes out and all the air comes out of the tube. This has happened with EVERY one of these tubes. I have never been with my regular Kenda (Q Tubes) from my LBS. I was stuck pumping…
