Paragon Valve Cores – Presta
What It Is
Paragon Presta Valve Cores are small replaceable internal components that screw into the inside of a Presta tubeless valve stem.
They control airflow through the valve and are commonly used in MTB, gravel, and road tubeless setups—especially where sealant is used inside the tyre.
Think of them as the “working gate” inside your valve.
How It Works
- The valve core screws into the Presta valve body
- It opens and closes to allow air in or out of the tyre
- When tightened, it seals the system airtight
- When loosened or removed, it allows:
- faster inflation
- easier sealant injection
- cleaning of blocked valves
In tubeless systems, sealant can sometimes clog the core—so it is designed to be serviceable and replaceable.
What It’s Useful For
- Replacing clogged or damaged valve cores
- Improving air flow during inflation
- Easier tubeless sealant injection
- Maintenance of tubeless MTB/gravel/road systems
- Fixing slow leaks caused by faulty cores
- Keeping tubeless valves working properly
Key Features
- Standard Presta compatibility → fits most tubeless valves
- Removable design → easy maintenance and replacement
- Precision threading → ensures airtight seal
- Sealant-resistant design → handles latex exposure better than basic cores
- Improves airflow when clean or new
- Compatible with most tubeless valve stems (including Veyga, Muc-Off, etc.)
What It Does NOT Do
- Does NOT seal punctures in tyres
- Does NOT replace a tubeless valve stem
- Does NOT fix rim tape leaks
- Does NOT inflate tyres by itself
- Not a standalone component—it only works inside a valve
Where It Fits in Your Cycling Setup
This is part of your tubeless maintenance system, not a riding component:
- Inside your tubeless valve (e.g., Veyga Presta valve)
- Works alongside:
- tubeless sealant (like Goat’s Milk)
- rim tape
- tubeless tyres
- Used during:
- tyre inflation
- sealant top-ups
- routine maintenance
Think of it as:
“the internal air control valve in your tubeless system”
Who It Is Suitable For
- MTB riders using tubeless tyres
- Gravel riders doing long-distance rides
- Road cyclists with tubeless setups
- Mechanics and home bike builders
- Riders maintaining their own bikes
- Anyone experiencing slow valve leaks or blockage
