Tubolito CX/Gravel 700C x 32-50mm, 42mm / 60mm Presta Valve | Light, Strong & Compact | Rim & Disc Brake Compatibility

I've used Cyclami, RideNow, Aerothan and Tubolitos. So far, these have been most reliable. The Cyclami and RideNow are too light and fragile for training or commuting. My tires have been Continental GP5000 TR, both 28mm and 32mm. As for feel and rolling resistance, honestly, there's no difference between them. For me, it comes down the safety and reliability.

This is a heavier duty version Tubolito. I carry it on my gravel bike for flats. It weights less and takes up less space than a std inner tube. Installation looks pretty standard - to ease loading into the tire just add a bit more air so it forms into its shape. Costlier that a tube, but to me worth it.

First off, I’m not one to write off a product within the first week of light use. However, in this instance I’m going to unload. The sales pitch Tubolito pushes is these “2x” stronger than butyl tubes is misleading at best. I’ve experience 2 failures in one week. I have absolutely zero confidence in the hi priced (34.00) tubes. They where mounted w/new 35mm Panaracer gravelking slicks on a new carbon wheel set, new rim strip & mounted w/out issue, meaning a straight forward set up. Three days on the new setup, I suffered a slow loss of pressure like a small puncture on the front wheel. A pinch flat usually causes a catastrophic loss of tire pressure, meaning an immediate flat. Remounted a butyl tube to get home then checked the Tubolito. No puncture or pinch… Valve stem was leaking at the base?? Next failure was 2 days later on the surviving wheel. Same issue as earlier stated. Slow loss of pressure mid ride. Used a butyl tube to save me from calling for a lift saving me a ride of shame. Again, no puncture, no pinch, but a slow loss of air inside the valve stem this time. Now… Road conditions was flat, clear of debris w/absolutely zero road hazards. I truly wanted to believe these “hi priced” tube would live up to Tubolito’s hype but… it’s just that, hype. Waaay overpriced, waaay too fragile. I’m going to set up my semi gravel rig tubeless, which I should have done in the first place. Tubolito’s ?? Steer way clear. If you need to run tubes on your rig, go latex w/a squirt of sealant for piece of mind…

works as described and packs down extremely tight. I just wish a product that works so great as a spare tube to ride with also had a removable core to work on deeper wheels without needing a specific valve extender.

Nice and light for packing away.

Best tube on planet earth! Strong as steel, light as a feather...

I packed two for unbound gravel and ended up having to use both of them in the middle of the race and they held up perfectly

These tubes are super convenient. Love their low weight and low profile. What I don’t like so much is their durability. Mid-race at Unbound last year, I needed to put in one of these after getting a small sidewall puncture that the tubeless setup couldn’t hold and where a plug wouldn’t worked. Even with a bit of gorilla tape on the rip and this (brand new) tube in place, I got a leak in the tire 20 miles after the change. A similar issue happened at another race on a different set of tires and a different puncture with a screw. Changed to the tube, which held up for a bit, but noticed considerable deflation before the finish line. Both experiences have me wondering whether the value is there. Light? Yes. Compact? Yes. Reliable? Not so sure.

The best spare tube going and added value with this kit of 2 plus proper parches

Top, alles in Ordnung!

Hola, yo creo que esta cámara está defectuosa, no es normal que haya saludo ese bulto

These are my new emergency repair tubes for my road bike running 32mm wide tubeless tyres. I've not needed one yet (I run Schwalbes...) but if I did, I am confident that these little and light beauties would serve the job nicely. I am loving the fact that they are tiny! They are so small I can chuck 2 in my saddlebag. They seem nicely made and did I mention they are light?! Wish they were a bit cheaper but worth it, even if I never use them just because of the size and weight - I will be carrying them on every ride after all.

チューブの継ぎ目からエアが漏れる個体があるようです。三本買って二本がダメでした。
