ContinentalCyclocross/Gravel Tube(Return to Product Page)

This holds air very well.

I've been using for years and really like how well they last.

I like to keep my life simple, and these tubes do that perfectly. Fit both my road wheels w/ 32mm Conti 5000 and gravel wheels w/ 40mm Conti Terra Trail. Long enough stem to work on my friends' rims, though mine are shallow. Nice mid-weight with decent puncture resistance but not thorn tube weight. Recommended.

These tubes are heavier than the standard Michelin tubes I'd been using on my Jamis Supernova with Clement Xplor Ush tires, but they don't feel as heavy or 'weighty' as the Kenda Thornproofs I used for a while on my Miyata 610 with Gatorskins. The Kendas felt like they were partially filled with sand, but these Continentals roll just fine. Glad for the upgrade at a reasonable price. One star withheld because the tubes're new and who knows how they will hold up over time.

This tube works great for cross or adventure bikes with wide tires 32-42 mm. The tube is supple enough but it also thicker rubber than a road tube as it should be. I have been running these on 2 cross bikes and have not had any issues.

wanted to match continental cyclocross/gravel tube with continental gravel tire expecting top performance from these products. i have been pleased with performance.

Worlds sickest tubes! Let's do this

Always happy with Continental- used for years

the tube itself is a little on the heavy side but considering I make it heavier by squirting an oz of stans in it i feel i shouldn't complain. being able to remove the valve core and add sealant was the my whole reason for getting this tube and it has held up well. no flats yet and that with running through a goat head patch.

I'm usually not a Conti guy, but I use these on my CXcommuter and am pleased. Strong, nice roll, seems like minimal air loss compared to others.

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.

Good tubes, a little spendy.

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

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!

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.

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