Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Performance MTB Hub: Designed for mountain biking, the Koozer XM490 Pro Boost Rear Hub features 6 pawls and 72 engagement points for rapid power transfer and smooth pedaling.
  • Boost Compatibility: Supports 148mm O.L.D. spacing, enabling wider tires and improved stability on rugged terrains.

Key features

  • 1. Advanced Material Technology

    • With an aluminum alloy construction, you can achieve a lightweight yet corrosion-resistant hub that reduces rotational weight compared to traditional steel hubs*. The rainbow gradient finish also ensures durability against environmental wear.

  • 2. Effortless Interactive Design

    • With a 6-pawl engagement system, you can experience 72-click smooth pedaling, offering 50% more engagement points than 3-pawl systems for rapid power transfer*. The sealed bearing design further simplifies maintenance with minimal cleaning needs.

  • 3. Boost-Specific Performance Parameters

    • With Boost 148mm spacing, you can accommodate wider tires (up to 2.6") for enhanced stability and traction on rugged terrain, outperforming non-Boost hubs in off-road scenarios*. The 28h spoke configuration ensures robust durability for high-stress MTB use.

  • 4. Scenario-Optimized Solutions

    • With a sealed ratchet system and aluminum core, you can maintain peak performance in muddy or dusty environments, ideal for aggressive trail riding or all-mountain adventures*. The design prioritizes continuous operation without compromising on reliability.

  • 5. Certified Material Compliance

    • With materials meeting MTB durability standards, you can trust its resistance to shock and corrosion for demanding off-road use*. Specific certifications (e.g., ISO) should be confirmed directly with the manufacturer.

  • Notes:

    • The rainbow gradient and alloy construction emphasize both style and practicality.
