Muc-Off Big Bore Lite Tubeless Valves

Upgrade your tubeless setup with valves designed to deliver high-flow performance, precision control, and robust construction for serious cyclists.

Why youll appreciate them

• Engineered with a straight-through internal design, these valves deliver up to approximately 230% greater airflow compared to a standard Presta valve making inflation and sealant injection much faster and easier.

• Built from 7075 aircraft-grade CNC-machined aluminium with a stainless-steel ball-valve component, the construction is rugged and serviceable for many seasons of use.

• Coreless design reduces clog risk and simplifies maintenance no need to remove a valve core to add sealant or rely on restricted airflow.

• Comes with multiple size options (30 mm to 80 mm) to suit different rim depths, and includes rubber bases and O-rings to ensure compatibility with a wide variety of rim types.

• Colour-anodised finishes allow you to match the valve to your wheel build for both style and performance.

Ideal for riders who

• Use a tubeless setup on mountain, gravel, or road bikes and want quicker inflation and easier sealant top-ups.

• Run deep rims, wide rims, or any custom wheel build where standard valve stems might fall short.

• Care about the build quality and longevity of every component in their system not just tyres and wheels, but the valving that supports them.

What it means for your ride
Faster inflation and more reliable valve performance mean less time fiddling in the garage or at the trailhead and more time riding. Because these valves support high-throughput air and work smoothly with tubeless systems, youll get better uptime with fewer hiccups.

Pro tip for installation
Ensure your rim interior around the valve hole is clean and free of old sealant, tape, or residue. Choose a valve stem length matching your rim depth, insert the valve stem with the included base and O-ring, and secure the locking ring by hand. Avoid over-tightening to protect the O-ring seal. Once mounted, rotate the wheel to distribute sealant and check for any air leaks before heading out.
