TubolitoCX/Gravel Tubo Lightweight Bike Inner Tube | Light, Strong, Compact, Durable, Puncture and Pinch Flat Protection | for Cyclocross, Gravel, Hybrid Bicycle | Presta Valve, for 700c

Tiny when packed. Easily cuts the space in half vs a traditional tube. Almost as fast as latex but without the chronic air loss

Judging from reviews all over the internet for the various Tubolito products, people find the tubes to either work perfectly or be utter trash. I ordered two of the gravel/cx tubes to replace Schwalbe SV17 tubes I was running on my CX bike. This saved around 100g of weight per wheel.The tubes are used with 35c Schwalbe G-One Allround tyres and fit, inflate, and hold pressure (45/50 psi front/rear) just fine. I have not had to re-inflate the tyre since first installing the tubes about 2 weeks ago, riding 25–40 km per day, 15% road 85% mixed gravel (light gravel / packed dirt).All-in-all a good purchase for my personal use.

I have a small Silca dabble bag and wanted the tightly wound spare inter tube pictured. That’s why I paid the high price. I use tubeless tires but it’s nice to have a backup. I hat I got (pictured) is maybe hardly smaller then a standard inter tube.

This is one of those products that are hard to review simply because I haven't needed to use it yet. This would be my last resort when the tire plugs failed and all the sealant from my tubeless tire leaked out. It is much lighter than a standard tube that I would use on a gravel bike.

First ride on this tube and i got a flat

Ever since I first heard about Tubolito's polyurethane tubes, I was intrigued by the idea of a tube that is both lighter, more compact to pack, and supposedly more puncture resistant than butyl tubes. Given the price, I did some research. I found just enough poor reviews in forums like Amazon to concern me, so I waited. Recently I finally decided to take the plunge and try it. I got 3 tubes which I run on my gravel bike in 40 mm tires. I got 2 flats on my first ride. I patched the holes with Tubolito's specially designed patches. They held for a while, including the next few rides. But, within about 5-6 rides I now have holes in all 3 of the tubes I bought. It's more flats than I've had on that bike in years. So, I'm giving up and going back to butyl tubes. It was unfortunately an expensive experiment.I will add two observations. One is that the tubes hold air between rides better than butyl tubes. It's not a critical feature, but a nice one to have if the tube were more durable. The second is that polyurethane seems a lot less stretchy than butyl. This particular model is marketed as fitting tires from 30 to 40 mm in width. That's a pretty wide range even for a butyl tube. With polyurethane, it takes a good deal of pressure to get the tube to completely fill a 40 mm tire, and the tube looks as if it's under a lot more stress when it is expanded to 40 mm. It's possible that the material would perform much better if it weren't stretched so much, and wouldn't be nearly as prone to flats on a 30 mm tire. Maybe the real problem with this product is that Tubolito needs to be selling these in a much bigger array of sizes. In any case, I just don't think I can recommend this product, and I hope that Tubolito is able to resolve the problems that some of us are seeing.

Despite horror stories of new tubes having leaks around the valve stem I tried it and was one of the lucky ones. I only bought 1 (for now). I don't expect I will have any luck patching it, but requires 3x more force to puncture, so there is the trade off. The weight is an incredible 56g on my scales. A cheap (vavert) 700x32c inner tube came in at 155g and the excellent schwalbe lightweight SV18 tube was 100g. The tubolito pressure needs a top up every week-10 days, which is reasonable as it's not flat, just a tiny bit soft. The Schwalbe sv18 is more like once a month/6weeks, but it is the gold standard for air retention.I was going to keep the tubolito tube as a spare because it is so small, but costs so much it'd be a shame not to use it. Rides great. Saving grams from the turning bits really does help acceleration. I'm probably not rich enough to justify such cost for inner tubes, let alone ones that are almost impossible to patch permanently, but will make a great gift for the cyclist who has everything.

2 crevaisons au lendemain de la poseFuite au niveau de la valve!!!!!

Sembra un accessorio ben fatto e ben presentato. Due sole osservazioni: troppo costosa e durata nel tempo. Credo che, se si diffonderà, il prezzo si abbasserà e allora diventerà davvero interessante. 5 stelle, per il momento.

⬆️ Ideal para llevar como repuesto por su bajo peso y el poco espacio que ocupa.⬇️ Precio

per la resistenza non saprei valutarla... e spero di non valutarla mai.comunque pesa poco, e insieme ai ricambi ci sta comoda.bene!
