## Description

Product description

Review: Great inner tubes - The thickness of the tire inner tubes were amazing
Review: No flats, great ride. - Seem to be holding up pretty well. Have almost a thousand miles on the tire at this time. No flates, and seem to wean really well. Look great on the bike and installation was no harder than any other tire i have put on the bike. Living in Florida there are lots of sand spurs that cause a lot of trouble for off pavement riding. I ride almost everyday pavement and trails. If i have had a punchure, the self-sealing is working great.

## Features

- Easy To USE ：The Self Sealing Bike Inner Tube is a self-repair for some small holes or very fine cracks. For example, after a long time, some places will leak air quietly,accidentally hit nails and other problems, which are easy to repair.

- Safe Bike Tubes：Pre-installed with Sealant to provide maximum puncture protection and prevent flat tires on your bike.The self-repairing inner tube is a thicker design, which is more durable than the normal inner tube.The puncture repair fluid circulates through the inner tube, automatically sealing the punctures.After testing, the leak can be repaired within 5~8 seconds under normal conditions.
- Excellent shock absorption ability ：The heavy, strong, highly durable butyl rubber made from these inner tubes is a perfect shock absorber to reduce vibration and eliminate the shock caused by bumps and rough surfaces on the road or pavement.

- Please note： Because the Self Sealing fluid is flowing, in order to prevent the liquid from flowing out during operation, please do not concentrate the center of gravity or the liquid near the air nozzle when pumping up
- Installation：26x4.0/4.50 bicycle replacement inner tube for easy installation and removal. Check the valve position to ensure that the installation direction is correct
- Tip：Before installing the inner tube, please put the inner tube into the water for inspection, if there are bubbles, it means that it has been damaged, you can contact us.
