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.

FAQ

Why is this listed as a Sunlite tube and not a Tannus tube?

Because Sunlite is the brand that actually makes the tube. Tannus ships this Sunlite tube as the recommended pairing for their 24 x 3.0-4.0 Armour insert, but the product itself is made by Sunlite. Listing the actual brand keeps things clear for service, warranty, and customer expectations.

Why is a 2.75-3.00 tube the right size for a 3.0-4.0 fat tire?

Because the Tannus Armour insert occupies volume inside the tire. The tube is sized down from a standard 3.0-4.0 tube to leave room for the insert. A standard-size 3.0-4.0 tube installed with the Armour insert will pinch and fail. This 2.75-3.00 size is the correct geometry for the system.

Can I use this tube without a Tannus Armour insert?

Yes, in a 24 inch tire that is between 2.75 and 3.00 wide. If your tire is wider than 3.00 and you are not running Armour, this tube will be undersized and overstretched, which shortens its life. For non-Armour 3.0-4.0 fat tires, use a standard 24 x 3.0-4.0 fat tube instead.

What does the removable valve core do?

A removable Schrader valve core means you can unscrew the core itself for full-airflow deflation, easier sealant install if you ever convert to a sealant-injected setup, or core replacement if it ever fails. It is a useful service feature on a tube you plan to keep around.

Best For

Cargo bike, fat bike, and 24 inch e-bike riders installing Tannus Armour on 24 x 3.0-4.0 wheels, and any rider running a 24 inch tire between 2.75 and 3.00 wide who needs a quality butyl replacement tube with a Schrader valve.
