Product Information
Full details
The BBB Tubeless Valves are an essential upgrade for mountain and road cyclists looking to ensure a reliable, airtight tubeless tire setup. Designed for enthusiasts and professionals alike, these valves feature a robust brass construction and a specialized rubber squared base for superior sealing. While they provide excellent durability and ease of maintenance with their removable cores, users should ensure the 80mm length is compatible with their specific rim depth to avoid excessive valve protrusion.

FAQs
Are these valves compatible with all rim types?
They are compatible with most tubeless-ready rims, but ensure the valve hole diameter is standard and the 80mm length suits your rim depth.
Can I use these for mountain bikes?
Yes, they are designed to perform reliably in both MTB and Road tubeless applications.
How do I add sealant through these valves?
Simply unscrew the removable valve core using a core tool, inject the sealant, and screw the core back in.
What is the benefit of the squared base?
The squared base design is engineered to sit more securely against the rim bed compared to round bases, creating a tighter, more leak-resistant seal.
Do I need special tools for installation?
No, they can be installed by hand, though a valve core tool is recommended for removing and tightening the valve core.
Troubleshooting
Air leaking around the base of the valve
Ensure the locking nut is tight and the rim tape is not wrinkled or damaged near the valve hole.
Difficulty inflating tire
Check that the valve core is fully tightened; if clogged with dry sealant, remove and clean or replace the core.
Pros and Cons
Pros
- Robust brass material for long-term durability
- Squared base provides a more reliable seal than standard conical bases
- Removable core makes adding tire sealant hassle-free
- Compatible with both MTB and Road tubeless systems
Cons
- 80mm length may be unnecessarily long for shallow rims
- Requires proper tightening to prevent base movement
- Does not include a valve core tool in every pack
Setup, Compatibility & Care
To install, push the valve through the rim hole and tighten the locking nut firmly by hand to secure the base. Do not overtighten with pliers, as this can damage the rubber seal or the rim tape. When maintaining, ensure the valve core is tightened correctly before inflation. For regular care, clean the threads occasionally and replace the valve core if you notice sealant buildup affecting airflow. Always verify that your rim depth is appropriate for the 80mm valve length to avoid interference.
