The Mavic XM 819 29" disc rim is the time-tested rim for hand building true UST tubeless wheels. Black.

  • UST Tubeless (Universal Standard for Tubeless): Localized strengthening of the rim area where the spokes exert the greatest force to improve resistance to micro cracking.
  • Fore: By drilling only one rim wall, Mavic made this rim four times more fatigue resistant and 40% more ridged.
  • Maxtel: Exclusive to Mavic, Maxtal aluminum alloy boosts rim strength by over 30% compared to 6106 alloy, for lighter and better performing rims.
  • SUP (Soudé Usiné Process): Produces an extremely strong, welded and milled rim joint offering superior wheel balance.

Cross-mountain UST Tubeless rim, for disc brakes only. Do not use rim tape.
Spoke Lacing Pattern - 3Cross

Selecting a cross pattern for your wheels is critical in terms of ride quaility. Our shop personally recommends a 3 cross pattern for mountain bike wheels, because of its overall strength and durability.
