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 Thorn Resistant Tube is thicker on the road side for puncture protection and thinner on the rim side for weight savings.

Protect yourself from flats with Bontrager's Self-Sealing tubes that instantly seal small hole punctures. And, for added flat protection, the 0.9mm wall thickness keeps punctures at bay.
