This Conti tube has nice thick material and fits my wide, 52 mm carbon wheels with plenty of stem to pump them up. I like the removable valve core that cheaper tubes don't have. I like them better than Conti's big M competitor's tubes.
I put these on my single speed bike that I ride to work 3 days a week, it is 20 miles there and back. Its a mixture of bike paths and bike lanes on pretty busy streets. Have not got a flat since I put them on 3 weeks ago. Before I had bontrager tubes from the local bike shop before with a few flats every so often, guess I have had better luck with these.
Have been using them for 2000 miles, 1 flat, excellent tubes.
So far so good. Would buy again.
no complaints, works as advertised and lasts much longer than the REI brand tubes
I paired these tubes with the Conti Grand Prix 4 Season tire and like them.
I don't really like presta valves but these function better than the other
brands I have had.
Nice lightweight tube. Great for the price!
These tubes fit great and hold up to punishment in my gatorskin tires. Definitely a must have.
Conti seems to make the most dependable tube on the market. I have never had a bad one (which I cannot say for some of the competition). In addition to its durability, it is relatively light with a solid stem.
Road bike. Excellent quality.
I have been using these tubes for the last few years and seldom had a flat unless the tires were well worn.
High quality, fairly low weight, long lasting, what is not to love about these Conti tubes????
My only complaint is that the valve stem is threaded, but that's fairly minor. It's a good tube which holds air for several days easily before needing to be pumped up.
Im an avid cyclist and rely on products like this to get me thru my rides day in and out.
Great quality tube. They do have replaceable valve cores. Just be care to check occasionally they are tight.
I had to switch to Continental from another brand of tube, Continental seems to have removable presta valves in the stems. Neither brand advertises a removable valve. What I do not like as much is that this tube has a shaft that is threaded, and the other was smooth. The smooth stem makes it much easier to fill the tube, which if you have 120 lbs tires you know you have to air up weekly. The other down side is that these tubes appear to be thinner. I put a new tube in and was airing it up and it exploded. I have to put slime in my tires because of the goat head thorns and even with a plastic tube guard the tubes still gets punctured. What I had to do is add slime to the tube, install it then air it SLOWLY, rotating the tube to allow the slime to disperse around the tire. Then I was fine. You have to squeeze the tire to make sure that the air is dispersing. If the tire does not feel the same all around you have to rotate it and allow the slime to flow down.
Continental road tubes have served me well year after year. Consistent quality at a reasonable price.
It's hard to get too excited about an inner tube. This one has a presta valve with a method of screwing it down to the rim, which I like. It makes inflation more stable. If you use a pump that screws to the valve, you have to be careful not to over tighten it, as you will unscrew the valve as well as the pump when disconnecting. Then you can start all over again! I imagine that would happen with any brand inner tube. Not extravagantly overpriced, It's always good to have a spare tube or two with you on a ride. I have confidence that Continental is not selling any duds to us dudes.
I put these on and haven't had a single flat....yet !! Seriously they were easy to put on and they have held up very well. They loose very little air.I haven't had to put air in the tubes in months.And most importantly to me like I said, I haven't had one flat since I put them on!!
Quick ship, good price!
