I built myself a wheel with a hub dynamo for wintertraining useing a bontrager rim. It turned out that the combo of the rim and my Conti Grand Prix 24 was an awful one to mount. I bought a dozen Conti extralight innertubes a while ago as they fold up way smaller than the regular ones. Problem is that they don't hold their shape as nice as the heavy ones and are a lot more prone to get pinched between the rim and the tire.
If you have a flat with deep frozen hands the last thing you need is a spare tube that's finicky to mount.
Does anybody have a favourite tube that is very robust and easy to install? The standard Conti one is pretty good, but maybe someone has other ideas.
