Your inner-tubes are one of the most critical components on your bike. Bontrager's are premium quality, standard weight tubes that keep you rolling. Get one more than you think you'll need—you can always use a spare.

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 Airlock Self-Sealing Tube seals small punctures so you can keep riding.

Specialized's Desert Protection Tube defends against flats in the harshest environments. It's thicker on the road side for puncture protection and thinner on the rim side for weight savings, while the Airlock self-sealing solution fixes most flats on the spot and prevents slow leaks.

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

Continental Light Tubes are made of a lightweight seamless butyl rubber and are individually tested for top quality. These tubes are nearly 30% lighter than standard tubes to make tires more supple and accelerate even faster.
