Bicycles get lighter, year by year. Steel gives way way to titanium, aluminum, carbon. But -- has this progress reached its limit? No, by no means!
You think air is light? Think again. The air in your bicycle's tires is compressed, mulitplying its weight as much as 800 percent. And it is Rotating Mass, which slows you twice as much as plain old moving-along mass! Worse, carbon dioxide from inflator cartridges weighs 152 percent as much as air. Carbon dioxide is a greenhouse gas, too!
Helium, on the other hand, weighs only 0.13 times as much as air!
Now, you can shed excess weight and avoid environmental impact, with the ShelBroCo Helium Inflation System. Subscribe to our service, and the ShelBroCo Helium Tank will delivered to your bicycle shop, team clubhouse or home workshop on a regular schedule, along with an ample supply of Shelbroco Helium Cartridges for on-road inflations.
No need for a clumsy pump or clunky compressor! the ShelBroCo Helium Tank is pre-pressurized! Each tank is good for dozens of inflations. For best results, use a new, uninflated inner tube, or purge before inflating.
(If running tubeless tires, inflate and then deflate to a low pressure several times before final inflation, to minimize the residue of heavy air in your tires. Have an extra tank on hand if you run tubeless!)
So, you're simply out of luck, because you exhausted your last ShelBroCo Helium Inflator Cartridge, miles from nowhere? No! Simply tap for help, with the ShelBroCo Helium Rescue App™ for iPhone or Android. With our Premium ShelBroCo Helium Road Service, you can even forget about the inflator cartridges (who doesn't?), or a pump, spare inner tube, patch kit, tire levers or (yecch) getting your hands dirty. ShelBroCo will exchange your wheel for a new one, already fully inflated with helium. Delivery is by truck or HeliumCopter. By special arrangement with Amazon.com, delivery by drone will be available soon!
Helium is light but the ShelBroCo Helium Tank is heavy. If the ShelBroCo Helium Tank falls on you, we told you so.
If overinflated, a ShelBroCo Helium-inflated tire may rupture or lift off the rim, resulting in an explosive release of helium, temporary alteration in speech patterns, hearing damage, and splatter with sealant and talcum powder.
Prolonged inhalation of helium may result in hypoxia, loss of consciousness, brain damage and death! Oxygen, not helium, may be used to revive exhausted cyclists. In case of emergency, we recommend that you also keep a tank of ShelBroCo Oxygen and a breathing mask on hand.
Available in your team colors!
ShelBroCo Oxygen, for emergency resuscitation (similar appearance) $ 199.95
Breathing mask $ 99.95

All that helium -- and I never thought of using it in tires!
Charles Goodyear
I could hardly have dreamed that my humble invention would have led to this astonishing development!
John B. Dunlop
Helium? Ja, das wäre gut, obwohl Wasserstoff noch leichter ist! (Helium? Yes, that would be good, though hydrogen is even lighter!)
Graf Ferdinand Adolf Heinrich August von Zeppelin
If you don't understand the advantages of helium inflation, I suggest that you return to this forum once you have acquired at the very least a bachelor's degree in physics or mechanical engineering.

Je n'ai qu'à penser à tout ça pour planer ! (I get high just thinking about this!)
