The name Airstop says it all. Michelin's Airstop tubes use a proprietary butyl rubber so your tires keep their pressure longer. And, the reinforced valve stem seam is ultra sturdy, too.

Giant's inner tubes are made from high-quality, standard weight rubber so you can keep on rolling.

When building your featherweight dream bike, don't forget the tubes! MICHELIN's Aircomp Ultralight tubes are nearly weightless for minimum rolling resistance and maximum speed.

These Giant tubes include flat sealant for reduced roadside maintenance.

Giant's thorn tubes feature thicker rubber that prevents some punctures and flats.

Keep the rubber side down and fully inflated when you choose MICHELIN's Protek tires. A specially-cut tread pattern reduces rolling resistance, and MICHELIN's rubber compound makes for an excellent grip. Grooves at the shoulders help increase traction on wet and greasy surfaces. A 1mm-thick anti-puncture reinforcement will help ensure nothing bursts your bubble, so you can enjoy the ride.
