Continental R28 Training Presta Long Valve Inner Tube - Black, 700C x 25-32 C/60 mm

My tires are getting chewed up by debris, but the tube isn't. A lot lighter than the puncture resistant tubes I had on previously so it works for me and the battle of rolling resistance.

I got a Pure Fix bicycle for Christmas. Unfortunately, one of the tire tubes blew out as I accidentally over pumped it. The colored rims on the bike look neat but they're also very deep meaning you need a long valve so it can protrude from the rim and you're able to get a bike pump on it to get air into the tube.This tire tube is the only one that I found on Amazon that fit the specifications and it's worked like a dream since I've had it installed. Highly recommended.

Inner tubes are boring and often completely overlooked, until you flat. There are many companies that sell competent inner tubes, and I've tried them all, but none are as consistent in quality as Continental. With that said, even Continental occasionally ships a dud, it's just much more rare than any other company in my experience. Very rarely are you going to have a Continental tube with a weak spot, a valve issue, and Race inner tubes are light but not fragile. To be sure, Schwalbe and Michelin, to name a few, are very good as well, I just find Continental to be just a little better.As far as these specific inner tubes, this is the 60mm version for 25-32mm tires. 60mm valves are best for rim depths between 30-40mm and these are really only necessary for 28-32mm tires, but they won't hurt to be used on narrower tires as well; even then, you can often get away with 25mm inner tubes on a 28mm tire, it's just not ideal for lifespan of the inner tube.All in all, I find Continental inner tubes to be a solid value, even though they tend to be more expensive than other big brands and I absolutely would recommend them to anyone.

I had flat less than 5 times in the last 10 years, riding on Continental tires and tubes, with around 3,500-4,000 miles a year. I know a good tire (in this case, Continental) with proper pressure has a lot to do with preventing flats, but so far I have pretty good luck with them. It's the best tubes you can get. I only bought them when they went on sale.The only thing you have to remember with these Continental tubes is they have removable valve core. I guess so you can replace them when the valve goes bad or to put some kind of sealant inside the tube to plug the leak (I never put sealant into the tubes, however). So when after you install the tube, use a valve core tool or a pair of plier to tighten it to prevent leak from the valve.

Not much to evaluate here. It is what it is. Its on the bike, and its holding air.

I use these on several bikes and have never experienced a factory defect failure. They may cost a buck or two more than some other tubes, but that is OK - When there is a tube failure I know that "I" caused it and that it mostly likely is not an issue with the tube manufacturing!

I have tire liners, saves me from a large number of flats I would get otherwise. Great tire, came in the box and it feels like a great fit in the tire itself. I will be using these as my primary tube of choice from now on!

Let me start by saying that I’m very familiar with bikes, bike repair, tubes, flat repair etc...Unfortunately I bought two of these tubes but the return process isn’t worth the hassle. The first tube I installed wouldn’t stop leaking from the valve stem even when completely tightened. The second tube I began to install and as always I gave it two pumps with the bike pump just enough to give it shape as I installed it. I noticed a dime sized dimple but continued with the install. Everything seemed fine but 3 miles later BOOM and I was left stranded, calling my son to come pick me up. If I had pinched the tube the pop would’ve been immediate. I purchased these to replace a tube and have a spare. I know it was unwise to ride without a replacement tube but I wanted to get back on the road. I would not recommend these tubes.
