Continental Contitube MTB 26 Tube

I had an issue with the Presta valve stem and contacted Continental, asking for a replacement valve stem. Instead, they sent me a whole new inner tube! More than I had asked for. Not sure yet about durability on this one, but in the past they have been good.

There were a few negative reviews of these tubes but I have found them to work fine. I do recommend you tighten the valve stem as I did have it back out when I removed the presta to schrader adapter but that isn't indicative of just this mfg. The tubes I purchased from my LBS had the same issue. Simply tighten the valve with a small adjustable wrench before installing and they work fine.

Keep in mind that this tube has a Presta valve, which is the long, pointy kind that racing bikes tend to have. The kind that most consumer bikes (at least in the US, not sure about elsewhere) have by default is a Schrader valve. If you do not have the correct pump you will need either a schrader adapter and cap or a Presta pump to fill it up. That said, it works fine on any bike (assuming you buy the correct size for your tire).You are probably already well aware of these matters, but whe I bought my first tires I was unaware of these matters and bought the wrong kind of tube. I hope that there are others like me who will benefit from this information.

Good tube but i don't like the strange to me valve to air it up

I felt like there are a lot of bad reviews up here on this product, so I wanted to chime in and say how well they have done for me. I just bought my fourth and fifth of this brand tube because they have worked so well. I ride my bike to work every day (6 miles each way) and take 26 mile rides along the strand in LA about once a month. I have 26" Schwalbe Kojak tires on a road bike, and these are some of the few tubes I have found with long enough presta valves to work for my rims/tires. Great tubes, last a while, I have popped two due to metal debris on the concrete, not faulty craftsmanship. Maybe others got a bad batch? Not sure, but take it from a daily biker when I say these tubes rock.

I’m sure the tubes will work fine but it took a week to get. Not sure why they sat at a facility for three days while in transit

It's a bike tube folks. It is rubber, round & holds in air. What sort of review are you expecting?Continental are the higher end manufacturer of tire products, so it should work much better than the cheap knock off brand from China, mine does (been there, done that).I did not get paid, reimbursed, of given anything for free (never do as I am not important enough online!) so you are getting my own unbiased, honest opinion & nothing but that. :-)

The tubes are fine so far. I will update in case they have any issue. What i will say is that not everybody know the difference between valve set types. I bought the wrong one, my bad, but the good thing is that my pum has both types, that’s why I didn’t care too much.
