The Sunlite 700c Road Thorn Resistant Schrader Tube fits narrow 700c and compatible 27 inch road tires in the 700 x 20–25 range. The 4.3mm thorn-resistant wall adds extra puncture protection compared to a standard tube.
Both variants use smooth Schrader valves with removable cores. Choose the 32mm or 48mm valve length based on rim depth and valve access.
