Description

Unlock your ride's full potential with the BOX Three Prime 9 X-Wide Multi Shift Groupset - the ultimate choice for versatile, high-performance mountain biking and gravel riding. Built with innovative Prime 9 Technology, this groupset redefines durability, efficiency, and simplicity by delivering a wide gear range with fewer components, reducing weight, and enhancing overall ride quality.

Materials & Engineering:

Constructed with high-strength, lightweight alloy components and precision-machined parts, the BOX Prime 9 Groupset is designed for rigorous off-road conditions. The robust X-Wide rear derailleur features an integrated limited-slip clutch, engaging instantly with constant torque to minimize chain slap and improve chain engagement, even on the most rugged terrain.

Performance & Components:

Equipped with an expansive 11-50t cassette, the groupset offers ultra-wide gear ratios, facilitating effortless climbs and powerful sprints. Prime 9 technology provides the same gear range as a 12-speed setup but with fewer gears, enabling smoother, quicker shifts with less effort. The 2-piece multi-shift pull lever allows riders to shift up to three gears at once, optimizing shifting efficiency and control.

Technology & Features:

- Limited-slip clutch on the X-Wide rear derailleur reduces chain slap and dropped chains.

- The cassette's wide ratio offers consistent, smooth gear progression across diverse terrains.

- Faster, more precise multi-shift capabilities improve ride responsiveness.

- Prime 9's unique design minimizes chain angle in lowest gears, extending chain and cassette lifespan by promoting a straighter chain line.

- Compatible with modern narrow/wide chainrings, the Prime 9 chain resists stretching over time, decreasing wear and increasing drivetrain longevity.

Style & Use Case:

Designed for serious mountain bikers, gravel grinders, and adventure riders, the BOX Prime 9 Groupset combines style, durability, and cutting-edge technology. Its sleek profile and reliable engineering ensure it performs confidently under demanding conditions, whether conquering steep climbs or roaring through technical descents.

Innovative & Differentiating Features:

The Prime 9 philosophy embodies the "less is more" approach-delivering wide-range gear capabilities with fewer parts, reducing weight, and increasing durability for a superior riding experience. Its simplified design reduces maintenance needs and enhances drivetrain reliability.

Upgrade your mountain biking or gravel setup with the BOX Three Prime 9 X-Wide Multi Shift Groupset - where innovative engineering meets exceptional versatility. Elevate your ride today with a drivetrain built for performance, longevity, and simplicity.

  • Enhanced Range and Efficiency with Prime 9 Technology delivering the same gear spectrum as a 12-speed system but with fewer components for simplified shifting and maintenance.
  • X-Wide Rear Derailleur featuring a limited slip clutch provides superior chain stability, minimizes chain slap, and prevents dropped chains during aggressive riding or rough terrain.

  • Engineered for Durability and Weight Reduction, the Prime 9 drivetrain combines fewer parts and high-quality materials to extend component lifespan while maintaining lightweight performance.
