ContinentalCyclocross/Gravel Tube(Return to Product Page)

The tube developed leak at the seam several miles into new ride. Checked the item, it has a leak at the seam where the radial and axial seams meet. Even though I realize that problems happen, this seems to be a design issue and might happen fairly often. I used the tune less than an hour. Is there any type of warranty? This is disappointing. I might go back to my old Tufo's.

Using these on my daily driver to commute. Only flat has been on a huge patch of glass that no tire/tube would've made it through. Gets beat up, but has held up well for me. Knock on wood.

I use them on my cross bike for winter training and on local trails. They aren't super light, but you don't really want thin tubes when they are designed to take abuse.

Conti generally makes tough products, if not always the lightest. This tube follows in that mold, as it's thicker than a regular tube, but I've also been able to get away with considerable abuse, running as low as 25 psi on some courses without damage.

Tighten up the valve before inflating or it will unscrew if your using a Lezyne pump. Otherwise nice tube, saves a few grams)

I have used these on a gravel bike for 3+ years with 0 flats. They hold air for a week+ without need to check pressure. Top notch.

It's difficult to get too excited about a bike tube but this tube is nicely constructed and has an extended threaded stem. It works perfectly with my fatty Gatorskins and I'm pretty confident the only time I'll see them again is when my tires wear out.

They've been pumped up in those brand new Contis for about a month now. Seem to be holding air great!

put these in my crossbike wheels for tarmac use since I woreout the stock tubeless tires that came with the Ridley-no issues whatsoever

Same as the tires... These tubes are well made and reliable for a smooth ride. They stay well inflated without significant air loss compared to other brands.

I have very deep rims and needed tubes with removeable core to add extension. Why don't the tube company make wider tubes with 80mm stems?

Holding air great, runs smooth

Just OK. I'd save your $$ for something better/lighter, or just buy cheap tubes and put your money into your wheels where it matters.

No issues after a season of running these tubes. Not one flat and I'm running my cross tires around 50psi off road. They have taken hard hits and keep on trucking.

These are thick and very well made ... the quality shows. I got these specifically for the removable valve core so I can add Stan's sealant. So far they have worked very well for cyclocross racing - no flats from thornsgoatheads or pinch flats. The advantage of the removable valve cores to add sealant provides added protection that's worth the extra cost.
