Maxxis Welter Weight Tube

This tube is designed for 700c tires with a width between 33mm and 50mm. If your tires fall within that range, it will be a compatible fit.

A removable valve core allows you to inject tire sealant directly into the tube for added puncture protection. It also makes it easier to use valve extenders if you are running deep-section rims.

The 0.9mm thickness is a middle-ground specification. It offers better puncture resistance than ultra-lightweight race tubes while remaining lighter and more supple than heavy-duty, thick-walled commuter tubes.

While it is compatible with 700c wheels, the 33mm minimum width requirement means it is optimized for gravel, cyclocross, or wider road tires. It will be too wide for standard 23mm or 25mm road tires.

This tube features a 60mm Presta valve. It is long enough for most standard rims, but if you have deep-profile aero wheels, you may need a valve extender.
