The Continental Road Race tubes are a high quality product for road cycling both training and racing. I use them with my Continental Grand Prix 4000 S II tires. One of the best things about the tubes is that they come in a variety of stem lengths. I have two sets of deep rim carbon fiber wheels on my road bikes and being able to get the longer stem is a key feature of this product. The tubes are long lasting and are great when paired with almost any wheel tire combination you have. Highly recommended.
Dunno if its the new Conti GPs or these Conti tubes I bought in conjuction but wow, my rides a lot more supple than it used to be. Yeah, its probably the tires but a fresh set of tubes cant be a bad idea either. I like em.
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.
Continental Race Road Tube is a excellent compromise between pliable weight and durability. Not too light and not too heavy.
Beware that these inner tubes have removable stem cores. If you find you have a very slow leak, check if the stem core is tight. You will need a 4.5mm open end wrench or a small vise-grip type tool to tighten the core.
Also, for vintage thin cross-section rimes, I wish the stem was shorter.
Can't say I have a lot to say about tubes. This one is completely fine. No issues. Happy to buy again. Only reason for 4 stars is I cannot come up with a reason to be in love with them, but have no complaints whatsoever.
I bought a couple of these tubes to use in an old school single walled 27 wheel. I liked the stem size. At 42mm instead of 48mm (too long) or 32mm (too short), these were the goldilocks size, just right.
But what impressed me most is that they held air pressure better than most any other light weight tube I've used. So I tried them in my 26er and had the same results. Before I knew it was was switching my 700C wheels as well.
I know many will say a tube is a tube and only as good as the tire that surrounds it. But for me, the light weight, perfect stem size and proven less air lose makes this my choice for tubes going forward.
Ive been running continental tires for years and love them. Just got a new bike that requires valve stem extensions. To use extensions, the core needs to be removed. These tubes have removable valve cores. Now I need to fall in love with these tubes.
These are nice tubes. Heavier than what I would consider racing tubes but I'm not a racer just a casual rider wanting durability and not necessarily light weight. I like the length of the valve stems. Perfect tube for me and will be ordering more for the future.
