Slime Smart Tube

This tube is designed for 26-inch wheels with a width range of 1.75 to 2.125 inches. Before purchasing, check the sidewall of your current tire to ensure the ISO diameter and width match these specifications.

The tube comes pre-filled with a liquid sealant that coats the inside. If you run over a thorn or sharp object, the air pressure forces the sealant into the hole, creating a plug that seals punctures up to 3mm in diameter automatically.

Yes, it is significantly heavier than a standard tube, weighing in at 589 grams. The added weight comes from the thicker 3.6mm butyl walls and the pre-installed sealant, which are designed for durability rather than lightweight performance.

Yes, this tube features a standard Schrader valve, which is the same type found on most car tires and standard bicycles. It is compatible with almost all standard bicycle pumps.

A removable valve core allows you to easily add more sealant if needed or replace the core if it becomes clogged or damaged. It makes long-term maintenance much simpler than with a fixed-core valve.

The sealant formula is non-toxic and water-soluble, making it safe for the environment. While it is contained inside the tube, it is easy to wash off with water if you happen to get any on your hands or bike frame during a repair.
