Product Information
Full details
The BBB CoreCaps Valve Caps are designed for cyclists looking to simplify their tubeless tire setup and maintenance. They offer a massive airflow design that allows easy tire seating with a standard pump, eliminating the need for an air compressor. A key benefit is the prevention of sealant clogs, ensuring consistent pressure. However, users should be aware that these are Presta-specific and require a Presta-compatible pump head if not using the Schrader conversion feature.

FAQs
Do I need an air compressor to use these?
No, the primary benefit of the BBB CoreCaps is their ability to seat tubeless tires with a standard floor pump, eliminating the need for an air compressor due to their massive airflow design.
Can I use my regular Presta floor pump with these?
Yes, while the CoreCap converts to Schrader compatibility, it remains fully functional with your existing Presta floor pumps.
Will sealant clog these valves?
The oversized opening and robust design are specifically engineered to prevent tubeless sealant from gunking up the valves, ensuring a clear air path.
Are these compatible with Schrader valves?
No, the CoreCaps are designed to replace the Presta valve core. They are compatible with Schrader pump heads for inflation but require a Presta valve base in the rim.
How do I clean the valves?
You can rinse the valves with water to remove any dried sealant. Avoid harsh chemicals. Periodically check for debris.
What are they made of?
The CoreCaps are constructed from high-grade anodized aluminum, providing a durable and rugged system.
Can I adjust tire pressure quickly with these?
Yes, the system is always open for airflow but sealed against the elements, allowing for faster and more convenient mid-ride adjustments without needing to unscrew small nuts.
Troubleshooting
Tire will not inflate or seat
Ensure the CoreCap is tightened securely to the rim. Check that the tire bead is properly seated on the rim. Try a different floor pump to confirm pump functionality.
Air is leaking around the valve base
Remove the CoreCap and reapply rim tape if necessary. Ensure the CoreCap is screwed in straight and tightened firmly by hand. Check the rim tape for any damage or holes.
Sealant is blocking airflow
Remove the CoreCap and flush it with warm water to clear any dried sealant. Ensure sealant is added correctly after valve installation.
Valve stem feels loose
Hand-tighten the base of the valve stem into the rim. If it continues to feel loose, the rim tape may need replacement.
Pros and Cons
Pros
- Effortlessly seats tubeless tires with a standard floor pump.
- Prevents sealant clogs for consistent performance.
- Dual compatibility with Presta and Schrader pump heads.
- Durable construction withstands heavy use.
- Simplifies tire pressure adjustments.
Cons
- Requires a floor pump for initial tire seating (though no compressor needed).
- Oversized opening might be less ideal for those preferring extremely fine air adjustments with very sensitive gauges.
- Presta valve base required; not compatible with Schrader valves directly.
Setup, Compatibility & Care
Setup:
- Ensure your wheel is set up for tubeless use with rim tape and a tubeless-ready tire.
- Insert the BBB CoreCap valve into the valve hole in your rim, similar to a standard Presta valve.
- Tighten the base of the valve securely by hand.
- Add your preferred tubeless sealant through the valve opening.
- Mount your tire and inflate using a floor pump. The massive airflow should help seat the bead.
Compatibility:
- Valve Type: Designed for Presta valves. The CoreCap itself replaces the traditional removable Presta valve core.
- Pump Heads: Compatible with both Presta and Schrader (car-style) pump heads due to the integrated conversion feature.
- Tire Systems: Suitable for all tubeless-ready bicycle tires and rims.
Care:
- Occasionally, rinse the valve with water to remove any dried sealant residue.
- Inspect the valve for any physical damage before each ride.
- Avoid using harsh solvents that could degrade the aluminum or seals.
