This tube is designed for 27.5-inch wheels with a tire width between 2.0 and 3.0 inches. Please check your tire sidewall to confirm your current wheel diameter and width match these specifications before purchasing.

Yes. The tube features a removable valve core, which makes it straightforward to inject your preferred sealant to help prevent or seal small punctures while riding.

The 0.9mm thickness strikes a balance between durability and weight. It is thicker than ultralight racing tubes, offering better puncture resistance for trail riding without adding excessive rotational weight to your wheels.

This tube uses a Presta valve, which is the standard thin valve found on most modern mountain bikes. You will need a pump compatible with Presta valves.

The valve length is 48mm. This is generally sufficient for standard mountain bike rims, but if you are using deep-section rims, you may need a valve extender.
