Eclipse Endurance inner tube review – 35g light and (so far) reliable

An Eclipse Endurance inner tube on the scales, with the scales reading 35g.

It’s difficult to subscribe too closely to weight saving on every element of a bike when you could reduce overall weight by losing more off yourself than any carbon seatpost or – in this case – mega-light bike inner tube could ever save on a bike-and-rider’s combined weight. A heavier, regularly ridden bike will always make a better rider than a never touched dream build.

Even so, we as cyclists are suckers for the latest fad, and here are some very light inner tubes. They’re so light, in fact, that they showed a lower weight on my scales than advertised by the brand: 35g vs 44g (but interestingly, 44g including the box). This way round rarely happens, most products I review are at least a little bit heavier than the manufacturer claims.
