  • CD Light Process – The rims of the CrossMax SX feature a shot-peened and gray anodized finish. The shot-peening is done in order to create a  micro surface hardness of the rim. The process helps increase the durability of the rim over time from external forces applied to the rim.
  • Fore Drilling – The rims are drilled in such a way that only the inner wall is penetrated. This works well for tubeless mounting because it allows for a smooth rim bed with no imperfections. The Fore drilling method makes the rim 4 times more resistant to fatigue stress as well as increases rim rigidity by 20%.

  • Increased Internal Width: The internal rim width is increased for 2010 to 21 mm. This sets up a nice tire profile for aggressive riding.
  • Tubeless: The wheelset can be easily set up for tubeless (UST valves included with the wheelet) or traditional tubes.
  • Advanced Materials and Construction: The rims are made out of Mavic’s exclusive Maxtal aluminum alloy. It is an alloy that is used to create a lighter and stronger rim. The rim is constructed using Mavic’s SUP process. The rim is welded and milled at the joint to create a extremely strong bond. The construction technique also helps in making sure the rims are created with more precise overall balance.
  • Rim Weight Reduction:  The CrossMax SX rims feature ISM which stands for Inter Spoke Milling. Each rim has the space between each spoke hole milled out to  reduce weight while retaining the same rigidity. This allows the rim to have much less inertia for easier acceleration and braking.

  • QRM+ Cartridge Bearings – These cartridge bearings are double sealed with C3 internal clearance and topped with a micro-adjustability system. This system allows you to quickly adjust your wheels according to the feel and performance you’re after. The wheels can be set up tighter for to keep out the elements and add more precision or ran more loose for the least amount of drag.
