They're just basic tubes, always nice to have some spares handy. They're around 85g for the ones I weighed, so very mid range. The valve core isn't removable, so if you need a valve extender this won't be compatible with the good ones. There's also glitter on the tubes for some reason?
I'd like to reiterate Scott's question below. To clarify, I run HED Belgium Plus clinchers (interior: 20.5mm, exterior: 25mm). I'd like to run a 25mm Rubino or Open Pave. Will a 23mm tube work? Do I need to size up to a 25-28 tube? Pack in my Luddite ways and get latex?
I've seen 25mm tires swell to 27+ on the Ardenne or Belgium Plus rims. Thanks for any help you can provide.
I like the tube. It shows up without holes in it. I put holes in it. Unlike the lucky gentleman, Matheus, I rode only 100 miles on mine before getting two flats in a week. sucks for me. THe first was a blowout as evidenced by the abrated sidewall of my rear tire. The second is still a frustrating mystery as it stranded me last night (as of this writing) on the side of the road with a crap hand pump. THumbing for a ride in front of a grocery store would SEEM easy, right? in the dark, wearing a bib, no problem! I'm lucky i bought three of these, but i am wishing i'd picked up about 8 more. As long as my route has construction and a graded (read:being repaved) road, i'm probably going to experience this joy a few more times in the coming weeks.
Installed these tubes in both wheels along with new tires and new rim tapes. 500+ miles now and they are holding up very well with no flats and no significant leakage. I used my bike for both daily commutes and long road trips.
I got some of these and the cores don't seem removable to me. I'm I missing something? Not twisting hard enough? (normally tubes w/ removable valve corse have flat sides on the threading, which these don't appear to have).
The Vittoria Ultralite Tube comes in two models; a 42mm Presta threaded non-removable core (85 grams) or a 51mm Presta smooth valve removable valve core (90 grams). With the 51mm removable core, there should be a flat side on the threading for easy removal of the core, though for the first removal can be a little troublesome.
These bad boys are a reasonable price and hold up well if you know what you are doing. At one point I was ridding about 60-80 miles per week and a single tube inflated and installed properly lasted well over a month! Make sure you get tires that can hold a higher PSI because these bad boys run perfectly at 125 psi!
I've had a cutter bones with Fyxation Session Dual Compound Tires for 3 years now and have only used these tubes to support my ride. They are all you need in a tube. Great price, durable, and light. They are easy to install and fill. Recommended for anyone looking for a reliable commuter/bar bike.
I have these in my mavic ksyrium equipe wheelset, running mavic tires over them with about 1,800 miles on the set currently. I run them at 110-116psi. Have hit some gargantuan potholes, ran over glass, etc, in the time I've had these on and never had a flat. Within a day or two of pumping them up they tend to "leak" down to about 85psi and stay there. I check tire pressure and inflate before every ride as a habit, so I dont mind that. after having bontrager tires blow out for no apparent reason on me, I'm a fan of these.
