GOT QUESTIONS? WE'VE GOT ANSWERS.
Yes - every insert ships with a Gnarly High-Flow Valve, designed to handle inserts and sealant flow.
They’re compatible with any wheel size, but designed to fit specific tyre widths. Trust our recommended tyre fitment guide and your inserts will fit perfectly.
Yes - just rinse it off and reinstall in a new tyre of the same size range.
Nope - it’s ultra light and disappears under you once installed.
No. You'll need to convert to tubeless.
GNARLY inserts act as a protective barrier between your rim and tyre, helping prevent:
• Rim damage from hard impacts
• Tyre burping under aggressive riding
• Loss of tyre support at lower pressures
With GNARLY protection installed, you can focus on the trail—not worrying about damaging your wheels.
Tubeless tyres are designed to run lower pressures for better grip and control—but lower pressures also increase the risk of rim damage and tyre burping. GNARLY Tubeless Tyre Inserts provide the protection and support your wheels need when the riding gets rough.
More than just rim protection, GNARLY inserts enhance the performance of your tubeless system, improving suspension feel, traction, and tyre stability. The result is a smoother ride, better handling, and more confidence to ride harder and faster.
We call this The GNARLY Effect.
GNARLY inserts are designed to be simple to install.
If you can fit a tubeless tyre, installing a GNARLY insert will be easy. All you need is:
• A sharp knife
• Tubeless sealant
• Tyre levers (optional)
It's a one-beer job, so you’ll be back out riding in no time.
GNARLY inserts are engineered to deliver protection without adding unnecessary weight.
A lighter wheel accelerates faster, climbs easier, and responds quicker to rider input.
Typical weights (based on 29" wheels):
• Gnarly Grey – 84g
• Gnarly Blue – 92g
• Gnarly Black – 116g
For smaller wheel sizes such as 27.5", inserts will be even lighter.
