Specialized Inner Tube

Yes, this tube is designed for 700c wheels with an ISO diameter of 622, which is the standard size for most modern road, hybrid, and commuter bikes.

The tube features a reinforced outer wall designed to deflect thorns and sharp road debris, while the inner wall remains thinner to keep the total weight reasonable. This balance provides extra durability where you need it most without adding excessive rotational mass.

A 40mm valve is standard for most traditional box-section rims. If you are using deep-section aerodynamic wheels, you will likely need a longer valve or a valve extender to reach the pump head.

Yes, you will feel a slight difference in weight compared to a race-focused, ultra-light tube. However, the trade-off is significantly better puncture resistance, which is usually a better priority for daily commuting or long-distance touring.

No inner tube is completely flat-proof. While the reinforced construction significantly reduces the likelihood of flats caused by thorns and small debris, you should still maintain proper tire pressure and check your tires regularly for embedded glass or sharp objects.
