Since we're talking latex inners and as some of us often receive questions about which ones to buy and so on, I thought maybe this would be a good place to list what's still around.
If you know other brands that still can be bought or know for certain that brand/model x, y or z is still being produced, let us know.Current production:Challenge
Valve stem lenghts: ?
Red pigmented latex inner tube looking similar to Vittoria old production, possibly same manufacturer?Vredestein
Valve stem lengths: 36-50-60mm
Weight(s): 55g (36mm)
Probably the only unpigmented latex inner tube still available today. This is what the inner tube inside the best tubulars looks like.
Not sure if this is curent production or NOS. If anyone can confirm?Michelin
Sizes: 18-20 and 22-23mm
Valve stem lengths: 36 (18-20 and 22-23) , 42 and 30mm (22-23mm only)
Weight(s): 70-80-82g respectively (this can't be correct)
The most commonly found (at least in Europe) latex inner tube. Green colour. Not sure if this is curent production or NOS. If anyone can confirm?NOS (New Old Stock)Vittoria
Valve stem lengths: 42-51mm
Weight(s): ca. 70g for 51mm stem
Red colour. Used to be available in various quality levels among which one being called Gold.
Occosionally I come across inner tubes from other brands such as Continental and Schwalbe. Not sure where or who made them but the Conti looked like a Vittoria and Schwalbe was as black as butyl, the latter could be NOS from when they'd bought Swallow in Thailand.
I am not including rebadged ones as being offered by some bike brands as these are no different AFAIK.
If you know of any other (true) brands or missing data, let me know and I'll update this post.
