Because it's hard to know when you're going to get a flat, it's always good to have extra tubes on hand. Specialized's Turbo Ultralight Road Tube w/Talc is lightweight to save rotational weight. The Talc lets the tube move easier inside the tire for a better ride with fewer flats.

- ISO Diameter: 406 / 20" BMX - Tube Compound: Butyl - Wall Thickness: 0.9mm - Valve: Presta - Valve Shaft: Threaded - Valve Core: Removable

Giant's inner tubes are made from high-quality, standard weight rubber so you can keep on rolling. These tubes feature threadless valve stems and removable valve cores.

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. - 98g - 52mm valve length

- Size: 700c x 23 – 25 - ISO Diameter: 622 / road / 29" - ISO Width: 23mm, 24mm, 25mm - Tube Compound: Butyl - Valve: Presta - Valve Core: Removable - Valve Shaft: Threaded - Weight: 125g (32mm), 126g (48 & 60mm), 128g (80mm)

These are no ordinary bicycle tubes! These extra strong inner tubes stop flats for 2 years because there is Slime inside. - No more flats for 2 years! - Extra strong with Slime sealant inside - Instantly seals tread area punctures up to 1/8" (3mm) in size - Seals multiple punctures repeatedly - Non-toxic and non-flammable - Cleans up with water

Nothing in the cycling world is more infuriating than flat tires. We get it, because we get them just like you. But with our Desert Protection Schrader Valve Tubes, you can minimize, if not eliminate, flats at the terrible hands of debris, thorns, or whatever else is halting your rides. Starting at the basis of the construction, we designed the tube to be thicker at the outer side, the part against the tire, in order to stop pesky bits from puncturing all the way through the tube. We then make the inner side, the part against the rim, thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection. We didn't stop there, however, as these tubes also feature our Airlock sealant that coats the tube for permanent protection against punctures. Not only this, but the sealant is designed to work continuously in order to prevent slow leaks from occurring, so erring complete catastrophe, you won't have to worry about flatting when you're riding over debris. We even addressed the common issue of sealant pooling with a completely homogenous design, so the tire/tube combo will always roll smooth and even. - Thicker construction on the outer side (against the tire) enhances puncture protection. - Thinner construction on the inner side (against the rim) maximizes weight savings. - Sealant coats the tube for permanent protection against punctures. - Non-toxic, non-separating formula will last the life of your tube. - Designed to work continuously in order to prevent slow leaks. - Homogenous design prevents puddles with no need to shake. - Will not dry out like the many other sealants.

- High-quality, ultra-low weight tube that retains air just as well as conventional butyl tubes - Possesses the same resistance to punctures - 40mm valve length

We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, there's no better way to ruin a beautiful ride than with a thorn in the tube. No need to worry, though, because we designed our Thorn-Resistant Presta Valve Tubes to combat pesky pricks of all shapes and sizes. Starting at the basis of the construction, we designed the tube to be thicker at the outer side (the part against the tire) in order to stop pesky bits from puncturing all the way through the tube. Then, at the inner side (the part against the rim), it's actually thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection. - Thicker construction on the outer side (against the tire) enhances puncture protection. - Thinner construction on the inner side (against the rim) maximizes weight savings.

Giant's inner tubes are made from high-quality, standard weight rubber so you can keep on rolling. - Valve length: 48mm

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

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.

- Designed to improve rotational stability by decreasing rotational mass at the valve body - Lightweight aluminum Presta-valve body - Removable valve core - Extenders are available and sold separately

Schwalbe tubes retain air pressure considerably longer than standard tubes. The quality and purity of the rubber mixture directly affects the quality of the tube.
