What Makes the Sunlite 24 x 2.75-3.00 Schrader Tube the Right Tube for Your 24 Inch Cargo or Fat Bike?

The Sunlite Tube in 24 x 2.75-3.00 (ISO 507) is a standard-fit butyl inner tube from Sunlite, a long-running US bike parts brand, built for 24 inch fat and oversized tires on cargo bikes, kids' fat bikes, and 24-inch utility e-bikes. The 32mm Schrader valve has a removable valve core for easy maintenance and works with every standard floor pump, hand pump, and gas station air pump. Quality butyl construction with good air retention is what you want when you need a replacement tube that just works without thinking about it.

Sunlite is the tube brand that Tannus ships as the recommended companion for the 24 x 3.0-4.0 Tannus Armour insert. If you are installing Armour on a 24 inch cargo or fat-tire bike, this is the correctly sized tube to use with the insert. The 2.75-3.00 size is intentionally smaller than the 3.0-4.0 tire it goes into, because the Armour insert occupies volume inside the tire and the tube needs that room to seat correctly without pinching.
