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.
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.
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.
Installed a new tire and Vredestein tube at the same time. Forty-eight hours later, the tire was flat with no apparent puncture. Replaced the tube with a second Vredestein tube. Saved the first tube to search for the leak but couldn't locate it. Another forty-eight hours and the second tube was flat. I have been refilling it for the past ten days. Works fine except the air is consistently gone within forty-eight hours. I suspect the stems are faulty. Is this a common problem with these tubes or did I just get a bad batch?
Terrible purchased 2 both had flats within a week, both slow leaks from stem!
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.
It's pretty much what everyone else has been saying about these tires. I've never been one to notice the subtleties in tires, but these are noticeably grippy. AND, no flats yet!
I can't sayfind anything phenomenal about this tube, but it seems to get the job done at the right price, so let's give it 4 stars...for 5 it really needs to stand out in some way.
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!!
