Teravail Thorn Resistant Tube

This tube is constructed with a thicker butyl rubber wall specifically designed to resist punctures from thorns, glass, and other sharp road debris. While it is heavier than a standard tube, it offers significantly higher reliability for riders who frequently encounter rough terrain or urban hazards.

Yes. Because this tube features a removable valve core, you can easily inject your preferred tire sealant to provide an extra layer of protection against small punctures.

This tube is labeled for 12-1/2 x 1.75 – 2.125 tires, which corresponds to an ISO diameter of 203mm and a width range of 47mm to 62mm. Please check the sidewall of your current tire to ensure these numbers match before purchasing.

This tube uses a standard Schrader valve, which is the same type commonly found on automotive tires and most kids' or hybrid bikes. It is compatible with standard bicycle pumps.

You may notice a slight difference in acceleration or rotational weight compared to a lightweight racing tube, but for most commuters and recreational riders, the trade-off is negligible. The benefit of avoiding mid-ride flat repairs usually outweighs the minor increase in mass.
