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

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.

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.

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!

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!!

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.

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

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.

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.
