Eclipse Inner Tubes - The World's Lightest Bicycle Tube!

Manufactured from completely new materials, Eclipse inner tubes are not only lighter than anything else on the market (a road tube is just 29grams!) but they also offer massively improved puncture resistance over conventional tubes too. Weight savings can be as much as ⅓ lb off a pair of conventional road bike inner tubes, ½ lb+ on XC and AM rigs, and as much as 1½ lbs off your DH sled. These new tubes are a fraction of the weight of everything else out there, and most importantly, it's rotating weight that you are shedding so the weight savings will be immediately apparent. A rotating mass is a heavier mass, so by saving just a few grams of rotational weight in a set of tyres or wheels will earn you significant dividends out on the road or trail. That translates into faster acceleration and quicker handling without the risk of 'burping' that you sometimes encounter whilst running low pressures on tubeless setups. The word 'light' doesn't even do them justice.
