The Continental Race Road Tubes do what they're supposed to - hold air. However, I wish that the length of the Presta valves were longer (48mm or so) for better rim clearance.
After a 4 flat day, I updated some older tubes with these. Then put a lot tough New england pothole filled road miles on them. Very happy these are going strong!
They just work and work well
It was easy to install and is so far a durable tube.
What more can I say. I have trusted Continental tires and tubes for decades That's why I continue to ride Continental.
Like most of Continental's products this tube is well made and durable. I haver been very pleased with it so far. Easy to install and doesnt add any significant weight to the wheel.
great inner tube, very seldom a puncture!
good reliable tube. some of the cheaper tubes seem to get bit more easily and can take more care to install. these work well at 100-110 psi and seem to last and work well.
I use these tubes in my Conti GP4000S tires. IMO a winning combo. Provides a compliant ride with better than average durability.
Use them for training and club racing
I trust this tube to do its job more than competing ones. The valve stem is top notch and holds pressure longer than others. I like the removable valve core so I can use a valve extender. You can expect to pay a dollar more per tube than for competitor's tubes. And 60mm valve stem length is fully that. A competitor's 60mm did not extend through my 52mm rims enough to get a pump head on it.
Haven't had the need to use them as of this date.
I've been using the Continental brand for years...Normally nothing wrong with them... I usually only have problems with innertubes when there's a tire problem..ie puncture, something imbedded in the rubber or a hole in the tire that causes the innertube to protrude and pop. I have to use a 60 mm valve stem so the expense is more but I stock up when I catch them on sale.
These are good tubes. I've run them exclusively for the past two years. No blowouts. Precious few flats. When I first started using them I thought roughly 1 in 4 were defective since 25% had a very slow leak. What I figured out is the valve assembly is not always fully tightened into the stem. Check each one before you mount it with a small adjustable wrench. Do not over tighten.. Assuming it's tight, tube is great.
The Continental Race Road Tube has been my go to for years. They are a combination of durable and light weight. I guess it could change itself, but given that they last so long, that's not really an issue.
Not very reliable. I had two pop the stem out while pumping them up. Certainly wasn't over inflated . Not to mention, too thin and easily punctured.
Bought four of these, got two flats on two consecutive rides for no apparent reason. Valve misfunctioned on the third one when I replaced the second flat, so all of my CO2 went into space, leaving me in the middle of freaking nowhere and having to ride 10km home on the rim. NOT HAPPY. The fourth one is already in the trash can. You can bet I won't make this mistake again.
Performed better than expected.
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 like the valve stem and valve and the valve does not seem to bend.
