With a strong asymmetrical design, the fast-rolling Crest MK4 rim from Stan's NoTubes can handle both gravel and XC tires—and keep a consistent airtight seal even under hard cornering.


  • Durable yet lightweight alloy construction with a welded joint and reinforced spoke bed
  • Low-profile rim shape offers excellent ride quality suited to gravel and short-travel XC riding; 25 mm inner rim width is optimized for gravel and XC tires up to 2.3 in.
  • 1.5 mm offset; BST-asymmetrical shape improves spoke angle, allowing for a stronger overall wheel build
  • Shape is designed to equalize pressure for easy tubeless inflation and strong tire retention on both sides of the rim
  • Stan's NoTube offers a 3-year warranty with 1-year crash replacement for this rim
