Experience superior lightweight performance with the ROCKBROS Bike Inner Tube, crafted for road cyclists who prioritize speed and efficiency. This TPU inner tube combines ultra-low weight—only 24–35g—with excellent puncture resistance and long-lasting durability. Its 700x18/32C compatibility fits most road bikes, ensuring reliable air retention and consistent tire pressure on every ride. A smart choice for competitive riders and performance-focused cyclists seeking a lighter, faster, and more responsive ride.
NOTE: Do not inflate this inner tube outside the tire, as it may cause permanent damage. Before installation, add a small amount of air to check for leaks. When mounting, inflate just enough to shape the tube, ensuring it fits smoothly against the tire’s inner wall before pressing and adjusting it into place.
