Frequently Asked Questions
Q: Is this 44mm tubeless valve stem compatible with both MTB and road bike rims?
A: Yes! This tubeless valve stem is designed to work with tubeless-ready MTB and road bike rims. The tapered rubber collar creates an airtight seal across a range of standard rim profiles. We recommend verifying your rim's valve hole diameter (typically 6mm) before purchasing.
Q: Can I add tire sealant through this valve stem?
A: Absolutely. The valve core is fully removable, allowing you to inject liquid tire sealant directly through the valve without removing the tire. Simply unscrew the valve core, add your sealant, and reinstall — quick and clean.
Q: What makes 7075 aluminum better for a valve stem?
A: 7075 aviation-grade aluminum offers a superior strength-to-weight ratio compared to standard aluminum alloys. It resists bending and damage from trail impacts while keeping the valve stem extremely lightweight — ideal for performance-focused riders who want reliability without added grams.
