XM 819 Disc is the only true UST rim available on the market. Stiff and durable, yet light, and topped with the added benefit of riding tubeless.

Mavic XM819 MTB UST Rim Technologies:

  • Maxtal: Light and strong Exclusive to Mavic, this specific aluminum alloy offers a higher weight to strength ratio than conventional 6106 alloy.
  • SUP: Stronger and smoother joint Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
  • Fore: Stiffer and stronger Instead of being drilled, the lower rim bridge is pushed on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.
  • UST: Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort while reducing inertia and flats.
