Mavic Crossmax Carbon S 29 Boost Wheelset 2026

The Mavic Crossmax Carbon S wheelset is built on a simple and formidable formula: accessible carbon precision and responsiveness to transform your XC or light Trail rides. Designed for those looking for more fun and performance, this wheelset offers lightning-fast acceleration and ultra-precise handling in technical sections.

Carbon performance with every pedal stroke

• Thanks to their 100% carbon fiber rim, these wheels offer exceptional lateral stiffness while maintaining the necessary compliance to absorb trail vibrations.
• 30 mm internal width: Perfect for mounting modern wide-section tires (up to 76 mm), allowing you to ride at lower pressure to maximize grip and comfort.
• Hookless profile: Strengthens the rim's durability and improves tire support during cornering.
• UST Tubeless Ready design: For perfect sealing, increased puncture resistance, and optimal efficiency.

Technological and durable hubs

• The heart of the wheel is equipped with the Mavic Classic aluminum hub, renowned for its reliability:
• Instant Drive 360: A dual-ratchet freehub system ensuring ultra-fast engagement (9°) for instantaneous accelerations.
• QRM Auto bearings: An automatic-adjust sealed cartridge technology that guarantees long-lasting smoothness without any functional play.

Versatility and Robustness

• Classified in ASTM category 3, these wheels are ready for demanding Cross-Country. With a total weight limit of 150 kg, they demonstrate a rare robustness for carbon wheels, allowing you to ride with confidence even on rough terrain.

Compatibility:

• These wheels are delivered with the freehub body version chosen at the time of purchase, but they are easily convertible to other standards (Shimano HG, Sram XD, Shimano MS) thanks to freehub bodies sold separately.
