I made the switch to tubeless a little over a year ago, but I always still carry this tube with me for an unexpected day when I blow a sidewall 10 miles from the car. 200 grams strapped to your frame with a Voile strap is worth avoiding the hike-a-bike of shame back to the trailhead. Happy Trails!
Great tube to carry on the trail for unexpected flats. I use a voile strap and keep one attached to my bike any time I'm doing a longer ride. They are also quite a bit cheaper than other alternatives and seem to be just as good.
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.
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.
Familiarity: I've used it once or twice and have initial impressions
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).
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.
