Mavic Crossmax SL Ultimate is the most dynamic XC wheelset Mavic has ever created. Lighter, stiffer, faster.

Weighing only 1380 grams, this wheel is the dream of performance-focused cross-country riders. Developed with input from top professional riders seeking an advantage. Mavic Crossmax SL Ultimate features an ultralight full carbon 29" rim for rapid acceleration and climbing without compromising stiffness and durability.

Mavic Crossmax SL Ultimate's adaptive rim construction, using a specific carbon layup technology, allows us to produce the rims with less material between the spokes. The spoke holes are reinforced with strategically placed carbon layers in a process that minimizes weight without compromising stiffness and strength. A lighter rim means faster acceleration, more efficient climbing, and a more responsive feel on the trail. The outer carbon layer features Mavic's new UD² construction for a distinct appearance and increased durability.

The carbon rim is laced with 24 straight-pull spokes, two-crossed for maximum power transfer and improved vertical compliance. The new lighter Infinity hub design optimizes lateral stiffness, and spoke lacing maximizes power transfer. Mavic's Instant Drive 360 freehub with a double-ratchet system provides quick engagement.

Crossmax SL Ultimate 30 is compatible with Center-Lock brake rotors.

The front wheel fits a 15x110 front axle, and the rear wheel fits a 12x148 axle.

The wheels come with valves, spare parts, and MTB wheel bags.
