Tubes: All Sizes/Types

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.

Continental tubes are made of seamless butyl rubber and are individually tested for top quality.
