Ride Prepared

  • Familiarity: I've put it through the wringer

Riding tubeless still leaves you vulnerable to the occasional flat, I always carry this tube encase of emergency.

I would recommend this tube for anyone mountain biking with a 29 inch wheel.

great back up for tubeless rides

  • Familiarity: I've used it several times

Love continental tubes.. I use them as my back up on my tubeless rides. Easy to stuff in my pack and easy to depend on if things go awry. Great tube for a pretty good price!

security when running tubeless

  • Familiarity: I've put it through the wringer

Solid tubes with a removable valve core. The 48mm stems work well with most carbon MTB wheels. Inexpensive peace of mind if you're running tubeless.

Always buy Conti

  • Familiarity: I've put it through the wringer

Bought these in other sizes so figured the 29er should be no different.

Love Conti Tubes

  • Familiarity: I've put it through the wringer

I have been using Conti tubes for many years, and these 29er tubes are great to pack around and keep as spares in my gear bag. While they have a removable core, I have never had to use them, but they always do their job and get me out when I have flatted.

These tubes seem to be a slightly above average thickness, so they hold up really well. They have 48mm valve stems with removable valve cores. The price is right too. Buy two, or three, or eight.

Right price, removable core--bingo

    I'm 100% tubeless on all bikes. But--gotta have spare tubes just in case. Needed to get my on-bike repair kit refitted with a tube as I used the last one when I slashed a side wall bombing through a rock garden. And although that tube survived the rest of the ride, I wasn't willing to deal with the slime on the outside of the tube to re-store it in my pack. Order a hand ful of these conti tubes. I was pleasantly surprised that they have removable cores (useful if you want to dose the tube with sealant or if you ruin/lose a valve core on a tubeless valve). Otherwise, they are a commodity product in my mind. Just like any other decent tube.

    Grab a couple

    If you haven't joined the tubeless train, it's time we get you set up on that front. Reach out to me directly and I can help you convert your current setup or a new setup to tubeless!

    Now that plug is over - these tubes seem solid. I have only had to use one briefly, but it held up, kept air in it and got me down the mountain. All you can ask for when having a tube for when your tubeless set up blows up on you (avoid sharp rocks at high aggressive speeds.. they aren't too forgiving).

      Tubes for when you need them

      • Familiarity: I've put it through the wringer

      Running tubeless means you keep tubes for emergencies. You don't want to use them, but when you need them, they're there. Continental is a mainstay in the tube/tire world and they do a great job. These aren't ultra light tubes, but they do the job and do it well.

        Better than a Tube Top

        • Familiarity: I've put it through the wringer

        Are you tired of walking your bike after missing that tranny on your favorite jump? How about after those darn rattlesnakes take a bite out of your current tube?

        Do you suffer from flat tires due to gnarlyness, shredfests, or send offs?

        Or perhaps you burped out all your tubeless sealant while scraping elbows on that berm?

        Regardless of the why, the solution is now here! Get your spare tube now!

        (Fine Print: Prices subject to change. I am not responsible for picking you up after tearing your spare tire so please don't message me to do so. No tube is indestructible. If you keep shredding your tubes, please go tubeless or run higher pressures.. If that doesn't work, then you're probably destroying your rims as well and have other issues. Please remember to spay or neuter your pets.

        Gravel Guts!

          Here in Kansas we ride lots of gravel. The flint hills are notorious for eating tires and tubes. Just did a 67 mile ride and not one problem. Sand burs are another pain on the road , no worries. Continental 29er tubes fit my Trek Fuel EX 7 - 2.0 gravel tires great. I will be buying a second set for my 2.30 dirt tires and see how they hold up to our rocky terrain on the trails this winter. I have recommended them to all my friends.

          can't go wrong with Conti!

          • Familiarity: I've put it through the wringer

          I use conti tubes on all of my bikes so I recommended this for a friend and bought it for him for a present.

          Long Stems for big rims.

          • Familiarity: I've used it once or twice and have initial impressions

          Lots of the current super-wide rims (think Enve M60, Ibis 941, and Industry Nine Torch) are also pretty deep. Most people riding them are running sealant rather than tubes, but these are the ticket for spares since they have 45mm valve stems. Tubes with shorter 35mm valve stems don't leave enough valve to get a pump or co2 inflator on.

          Always carry a spare

            I have switched my mountain bikes to tubeless, but always carry a spare one of these just in case I get a puncture that doesnt seal. A couple of other things you may want to consider purchasing are:


            Fine tubes

            • Familiarity: I've put it through the wringer

            I've been riding Park City trails a lot lately, and just barely swapped over my wheels to a tubeless setup, so I've been relying on good tire/tube setups for the past three months. The trails here are pretty rocky, and I do every so often get snakebite flats from hitting jagged boogers straight on. These tubes have been a life saver on a few occasions when I'm 15-miles out from home. I've flatted two (2) tubes that came with the bike, and one (1) of these after barreling down a rock garden at ~25 mph.

            Nothing fancy about them, but they work as good as the others. I'm not a tube geek, so don't ask me about weight.
