It's simply the best butyl tube I can find. The ride quality isn't as good as latex but far better than a standard tube. They hold air much better than latex over time as well. If you cannot or won't run latex tubes I find this to be the very next best option. My 2nd favorite in use daily tube.
I use this with road bikes mostly 28mm tires (conti GP5000 and panaracer GravelKing)and one 1 1/4 tire (panaracer pasela). These tubes are super. Easy to install, great quality and good balance of weight and puncture resistance. Just did the Cino ride with no flats
I wanted new inner tubes with my new Grand Prix 5000 tires. The old inner tubes were still good, but had gotten a little heavy from repeated refresh doses of Stans tire sealant. Why not start with everything new for just a few dollars more? Thats what I did. The quality and ease of installation of these tubes was clearly superior to the no-name brand I used to buy. Continentals products do cost more, but everything they make is of the highest quality, durability and performance. It was true 40 years ago when I was a young racer and its still true today.
I've come to expect quality in Continental products, having run my Bianchi road bike with GP 4000s tires for many years now. This is the first time I've gone with Conti tubes as well, and I'm glad I did. A cycling tour in New Zealand exposed us to some rough roads and more than our share of gravel. Punctures were the order of the day. The Conti tubes held up. Yes, we had one flat, but their frequency was way down for our group of 10, part of a larger group of 110 riders.
Appears to have identical high-quality when comparing to Conti race tubes made in Germany from a decade ago - the butyl, valves, fit, seam, etc. Great fit with 25mm Conti tire and standard Wolber rim. The missing yellow caps add a few seconds though.
These Conti inner tubes are as reliable as any brand and are available in 60mm stem length. Not all 60mm stems are as long as these. For instance, I bought a 60mm OTC Bontrager inner tube at my LBS, but the stem was too short for my 52mm rim height wheels. So I was unable to get a tire pump on the stem to pump up the tire. Additionally, I am happy that the Conti has a removable core, which allows it to be removed and inserted in a stem extender. The Conti inner tubes seem to hold air well and need very little topping off after two days. But, they will flat just like any other inner tube.
