Slime Self-Sealing Tube - 29 x 1.85 - 2.2 | 48mm Presta Valve

What Makes the Slime Self-Sealing Tube the Best Flat Defense?

The Slime Self-Sealing Tube takes the guesswork out of flat prevention by coming pre-loaded with Slime Sealant, which automatically seals punctures up to 1/8" the moment they occur. Sized for 29" x 1.85–2.2" tires, it fits a broad range of mountain bike and hybrid applications without any additional setup. The 48mm Presta valve is machined for smooth airflow and works with standard floor pumps and CO2 inflators. Once installed, the sealant actively coats the inside of the tube on every revolution, targeting weak spots before they become flats.

Slime's formula stays active for up to two years, delivering continuous protection through seasons of riding without any sealant top-ups or tube swaps. The tube is constructed from extra-thick butyl rubber for added durability and puncture resistance beyond what the sealant alone provides. It is compatible with standard 29er mountain, gravel, and hybrid tires and installs like any traditional tube. For riders who want to spend more time on the trail and less time fixing flats, this is a straightforward upgrade that pays for itself on the first ride.
