Bought for a set of 30mm deep wheels. The tube is ok but the stems are not 50mm. If you measure the rubber of the tube to the top of the plastic cap you get close to 50, but measured from the metal base (the part that counts) to the top of the valve you get 38mm. So if you dont need 50mm they are ok, but if you need a true 50 look elsewhere.

The fixed valve is a great feature of this tube. Many pumps that we use to fix a flat while on the road take the valve out when you release it from pumping the tube.
The other option is of course CO2.
I like to keep all my options open. Recently I went to use my CO2 but had by mistake left the valve open.
Poof, my Co2 was gone in a second.
My back up option worked.
I use these because they have removable valve cores and i stick my Enve valve extenders on them. I like that they come coated with a light powder right out of the box (vs. powdering them manually) and this lets them breathe while inside of the tire which helps mounting and prevents pinches.
They are not as supple as some other butyl or latex tubes i've used (Vittoria latex tubes are like butter) but they're durable and easy to mount and I don't notice any negative rolling effects.
These tubes are great value for the money. I've used these for several years, and the quality has always been very good. They are better than the Continentals that are pretty good quality but are thicker (and heavier), and the prices reflect that.
Valves failed on 3 out of the 4 I bought. If you look at the valve stem (even in the photo here on the product page) you'll see it looks like it was soldered in a back alley. Maybe it was, because the valve core jammed on two of mine, and the third failed tube wouldn't hold air from the start.
I hate valve extenders. They are difficult to get to seal properly, even with plumbers tape, and they can be a nightmare to remove if you get a partial flat tire. These are a great alternative
Have read other reviews of this product and can only say my experience has been quite different.
Installed one to replace a tempermental stock piece that came with the bike. Vredstien tires too.
Was surprised by the length of the stem, and the fact that there was no presta nut. After that though all was good. Powdered by something, they fit in easily to the race tires. Presta pump locked up solid to the nipple, no problem getting in air, no seepage during the chore.
Best of all it performed like a champ during my competitive event. Nice tube IMO.
I bought 8 of these tubes about a year ago (four for me and four for my daughter and son-in-law) and every one failed! They may have been old or a bad batch but they all failed on a seam or at the valve stem attachment location. I have run Vredestein Fortezza TriComp tires on my road bikes and always been very happy with the performance and longevity - I'll not buy Vredestein tubes again! You depend on your tires to be safe and stand up to what the roads dish out and when they do fail, the last thing you need is to find out your spare tubes are not any good!!

I often buy same brand new tubes with the same brand tires. This time I got burned on the tubes, because the presta valves were faulty and leaked air out of my tires after a short day ride of 60 miles. This is not acceptable to me and I cannot recommend this product.
Thanks for your review! Sorry to hear these tubes didn't work out for you. Please get in touch with our customer service department at [email protected] if you haven't already -- we'd love to make things right for you.
Apparently all but 50mm length comes with a removable valve core.
Be warned - for some reason Vred measures size including the needle, so they run short.
They are pre-dusted with something like talc which is nice - i've been having problems with tubes bonding with tires otherwise.
I've only purchased two of these tubes, so my experience is limited. The first one died when i locked up my brakes and my rear tire flatted while making an emergency stop going downhill fast. Not the tubes' fault. The valve on the second one is having trouble seating properly. I finished my first ride with it and the tire was quite low. Investigation showed the tube leaked around the valve stem. It would hold air until i screwed down the nut, then it would leak. After refilling the tire and pressing the nut repeatedly, it seemed to hold pressure ok. Not sure what the problem iswas. I'll check to see if it's holding air before my next ride.
bought 2 of these. They both leaked around cruddy glue job near valve stem before even getting them fully installed. Junk. Love the tires, hate the tubes.
Thanks for your review. I'm sorry you had trouble with these tubes! Please don't hesitate to get in touch with our customer service department at [email protected] so we can help you out with replacements for your defective tubes.
Have tried some of the other brands such as Sunlite and have gone back to Verdestein which seem to not only keep air better but also seem to have less issues with flats. A very reliable tube that I use in my Zipp 404 wheels without requiring me to use a stem adapter.
