Lightweight innertubes

[TimmS]

Discussed for road widths widths, but what are the best lightweight innertubes for 35-45mm width tires?

I found Schwalbe SV18 at 105gr, but can't seem to find any latex tubes for example..
Any ideas?

Challenge makes a nice latex tube, I have been running them for years, I also find that some Effetto Mariposa Caffelatex Tire Sealant works great as a preventative for smaller holes that would normally cause
a flat tire.

Have you found something interesting?

I would love something like Conti Supersonic, but for 35C tyre.

Nope, unfortunately.
For now I stick with the Schwalbe sv18 for now and maybe try to go tubeless once.

I'd like to second the Challenge Latex tube. Unfortunately they are hard to get in NL at the moment. :/

I've used the Challenge tubes, and wasn't impressed. They were flat-prone (happened on various occasions, on and off-road, including once while warming up on pavement, before States). They tended to develop leaks around the valve hole.
