7. FAQ

What are the advantages of carbon fiber tube sleeves?

They provide strong, lightweight, corrosion-resistant tube-to-tube joints without drilling, preserving the tube's structural integrity while enabling easy assembly and disassembly.

What is the significance of 3K twill and matte finish?

3K refers to the number of filaments per tow (3,000), and twill is the weave pattern that offers a distinctive diagonal aesthetic. The matte finish provides a non-reflective, premium look that is also more resistant to visible scratches compared to glossy finishes.

How can I customize the sleeve?
