Found: World’s Lightest Bicycle Tubes from Eclipse
Ask most riders what the single greatest upgrade to your bicycle is and 9 times outta 10 they’ll tell you it’s new wheels. Slap on a pair of stiff wheels, drop some rotational weight, and that sucker will feel revitalized.
Budget’s not quite big enough for a set of new wheels? A new pair of tires and some extra light tubes is a great way to start dropping the pounds. These ultra-light tubes are lighter than a (non-ghetto) tubeless setup and might just be what your bike needs for extra e-cred on the Weight Weenie forums…
As with most things, weight savings don’t come cheap. The 26″, 27.5″ and 29er tubes come in at 49.00 CHF (Swiss Francs). A 700c road tube is 59.00 CHF. (about $68 USD) They also don’t come without limitations – they’re not to be used with carbon clinchers stopped by rim brakes as the heat created can cause the tubes to burst.
The upside? Beyond the ludicrously low weights, they are reportedly very puncture resistant and can be easily repaired with their own special repair kit.
