Lightweight inner tubes

happytramp

I always thought inner tubes were all pretty much equal, however while browsing Chainreaction I found these.

Anyone have any experience with these? How do they compare to regular tubes strenght/weight/rolling resistance wise?

Well depends how light you want to go.. you can even go to 50euro per tube light: http://www.eclipse.ch/new/Tubes.html

Edit: The lightest tube i 've used was a specialized Ultralight Road something something weighting at around 70gr. A normal tube should be around 115-125gr. I honestly didn't feel any difference, I 've used all kind of tubes and could not tell anything different. I wish we had that good roads that we would notice that

I use the continentals on my good wheels.
to be honest, I can't tell the difference.
They're inclined to stick to the tyres, I put a bit of talcum powder on them.
They don't hold pressure that well. I have them at about 140psi, and I find,
that the pressure drops by about 20psi overnight.
There is a weight saving of about 50g per wheel, so I suppose, there has to be
some advantage.
I reckon, that a lot of it is in the head.
