State Bicycle Co. SuperGravel TPU Tube

The primary difference is material. TPU (thermoplastic polyurethane) is significantly lighter and more elastic than traditional butyl rubber, which helps reduce rotational weight and improves your bike's handling. It also offers better puncture resistance and holds air pressure longer.

This tube is designed for 700c tires with a width between 35mm and 43mm. It is specifically optimized for gravel cycling setups within that range.

Yes, you can use this tube with tubeless-ready rims. While it is not pre-filled with sealant, the TPU material is durable enough to handle the varied terrain typical of gravel riding.

No, the valve core on the SuperGravel TPU tube is not removable. It features a 40mm Presta valve, which is standard for most gravel rim depths.

Reducing rotational weight—the mass at the outer edge of your wheel—makes it easier to accelerate and climb. Even a small reduction in weight at the tire level can make your bike feel more responsive and agile on technical gravel sections.

Installation is similar to a standard rubber tube, but you should be careful not to over-inflate the tube outside of the tire, as it can stretch and deform. Always ensure the tube is seated properly inside the tire casing before inflating to your desired pressure.
