Slime Self-Sealing Tube

This tube is specifically labeled for 26 x 1-3/8 inch tires. Please check the sidewall of your current tire to ensure it matches this exact ISO size before purchasing, as 26-inch tires come in several different widths and diameters.

The pre-filled sealant is engineered to automatically seal punctures up to 1/8 inch (3mm) in diameter. It works best on tread punctures caused by thorns, glass, or small nails while you are riding.

No, this tube uses a standard Schrader valve, which is the same type found on most car tires and standard bicycles. You can use any standard bicycle pump without needing special adapters.

The sealant formula is water-soluble and non-toxic, which makes cleanup significantly easier than traditional tire sealants. While it is still a liquid, it is designed to be manageable if you ever need to remove or replace the tube.

This tube weighs 258 grams. While the sealant does add some weight compared to a standard, non-filled tube, most riders find the trade-off for flat protection well worth the minor increase in rotating mass.
