Lezyne Valve Stem CNC TLR 80mm Black
What Is It?
The Lezyne CNC TLR 80mm Black is a tubeless Presta valve set designed for mountain, gravel, and road bikes with tubeless-ready rims. It replaces your standard valve and creates an airtight seal between the rim and tyre using a locknut and O-ring system. The 80mm length makes it ideal for deep-section rims or wheels with inserts where extra valve reach is needed.
Key Features
- CNC-machined aluminium construction for strength and low weight
- 80mm valve length for deep rims and aero wheelsets
- Integrated valve core tool built into the cap
- T25 Torx tip for tightening valve into rim
- O-ring + grooved locknut for airtight tubeless seal
- High airflow design for fast inflation and sealant flow
- Compatible with standard Presta pumps
- Designed for use with tubeless sealant systems

Pros
✔ Excellent for deep rims (aero MTB/gravel/road setups)
✔ Strong CNC aluminium build quality
✔ Built-in tools (valve core + T25) for trail-side adjustments
✔ Reliable airtight seal with O-ring system
✔ Good airflow for fast tubeless inflation and sealant transfer
✔ Clean, premium look on modern wheels
Cons
✖ More expensive than basic rubber tubeless valves
✖ Overkill for shallow rims (60mm or 44mm may fit better)
✖ Slightly more parts = more to check during installation
✖ Can be tricky to size correctly if rim depth is unknown
Who Is It Suitable For?
- Riders with deep-section rims (40–70mm+)
- MTB riders running tubeless setups with inserts
- Gravel riders using aero or carbon wheelsets
- Riders who want integrated tools on their valves
- E-bike riders needing durable tubeless components
Who Should Use It?
This valve is best for cyclists who:
- Need extra valve length to comfortably attach a pump
- Run tubeless tyres regularly and service their own setup
- Ride technical trails or long-distance gravel where reliability matters
- Use rim inserts (which often require longer valves)
If your rim depth is standard (under ~30–35mm), the 80mm version is usually unnecessary.
Bottom Line
The Lezyne CNC TLR 80mm Black is a high-quality tubeless valve designed for deeper rims and serious tubeless setups. It stands out for its durability, integrated tools, and reliable sealing system, but its length makes it best suited for riders who genuinely need extra reach rather than everyday shallow-rim setups.
