SCHWALBESchlauch SV19A Extra leich 28x1.50-2.40' 40/62-622/635 SV40mm

Excellent, fast, light weight road bike tires. Good for pavement roads. Only lasts a season but gives you a smooth ride and solid puncture resistance. Very happy. Got a second set.

Quality, lightweight tubes. Despite the thin walls, these hold air very well compared with various standard tubes I ran before. I'm using these in 29x2.5 tires.

These are great light tubes that fit a very wide range of tire widths. I've used them on my touring bike for several thousand miles of self supported solo touring in the US and Canada in 700x32 Gator Skins and 700x42 Travel Contacts. I had a couple of flats and discovered that these tubes have some kind of white power in them that both slows the leaks down and marks where they occur on both the tire and tube! I never needed to fix a flat on the road because the leaks were slowed down enough that I could just pump up the tire every hour or so, and it was always trivial to find the hole and, if it was still in the tire. the object that caused the hole. Brilliant!, as Brits would say.These tubes, used in the Gator Skin tire on my front wheel, also made for a very comfortable ride. The fact hat they have replaceable presta valve stems is also important to me. I have had to replace tubes because I damaged the stem when pumping tires up on the road.Note added in late May:I 've kept these tubes as spares and when I first used one, it leaked down overnight. When I removed it for the tire and tested it, I found that that leak was in the valve. I ordered some replacement valve cores and replaced the core in this one. The leak is gone. They are great tubes, but I'll test them in the future before I use them!

Seriously, my favorite tubes. And the light one is spectacular!

This fit perfect for my German hybrid (bike that is)! I get a little lost trying to convert sizes or in case size ranges. This did the trick and with a reasonable price. My bike is back to functioning and ready to hit the pavement.

I got what I needed at a great price and in great time. The picture did not indicate what I ordered on the picture of the item, but it showed up as the correct item when I received it. 2 Thumbs Up!!

These are a lightweight tube listed on schwalbe's site as the SV 19A. High quality tubes from what I see, only reason I took off one start is the stated weight of 140g isn't exactly accurate, I weighed 6 of them and they varied from 146g up to about 160g. Still a high quality lightweight tube for a 29er mtb, I just wish manufacturer's were a bit more honest with weight ratings.

Been riding on this tube for over a week now. For some reason I tried a lot of different tube brands and they kept failing after couple days of riding, this time I tried shwalbe tube and bought a new tire from Walmart. Been working and holding up pretty good so far, the rubber felt a bit thin though and I had very hard time installing it. But I’m happy so far , holding 60psi and riding through town with a bad pavements.

Ravi de cette chambre à air qui peut servir de chambre à air de secours pour plusieurs vélos! Que ce soit pour mon VTT (28" *2,2") ou le gravel de mon fils (700*35C), la fourchette acceptable dans les tailles de pneus est très appréciable. J'ai malheureusement déjà du la monter sur mon VTT. Elle fait bien son office!Et en plus elle est légère, un petite avantage pour les reprises...La longueur de valve de 42mm est très bien comparée à nombres de valves de 68mm qui dénotent sur une jante classique.

No pesa nada 140 gramos y no abulta

Hmmh, Fahrradschlauch halt .. passt und hält die Luft. Presta-Ventil Standardqualität, nichts zu bemängeln. Dieser Schlauchtyp war auch schon in meinem neu gekauften KTM E-Bike eingezogen. Deshalb habe ich ihn wieder als Ersatz bestellt. Ober er besonders leicht ist, .... na ja, glaube kaum dass das bei einem E-Bike auffällt. Unkaputtbar ist er natürlich nicht. Sehr günstig, momentan hier zumindest, schon.

Bardzo się zawiodłem, ponieważ marka produktu świadczyła o dobrej jakości. No niestety nie wyszło. Po napompowaniu do 4 dętka strzeliła, efekt na zdjeciach. Nie polecam.

Arrivata in tempi rapidissimi, è leggera (pesata a 148g qualche grammo in più del dichiarato, ma non è certo un problema) e occupa poco spazio nel borsello sottosella. Probabilmente il suo uso principale è di camera d'aria d'emergenza per il rientro a casa, ma io l'ho montata sulla ruota anteriore con il nastro in kevlar della Vittoria. Direi che fa il suo lavoro a un prezzo onesto da un produttore che è una garanzia di qualità.
