Optimize your eBike performance with the BOX Three Prime 9 X-Wide Single Shift Groupset, designed specifically for rugged durability and seamless shifting. This innovative 9-speed groupset features Prime 9 Technology, a revolutionary approach that combines the simplicity of fewer gears with the expansive range of a 12-speed system-delivering exceptional riding versatility without added complexity.

Constructed with high-strength, lightweight materials, the BOX Prime 9 groupset ensures maximum durability and optimal performance on electric bikes. The robust components are engineered to withstand the increased torque and stress typical of eBike usage, providing reliable shifting over countless adventures.

Performance & Technology:

Boasting Prime 9 Technology, this groupset offers an expansive gear range using only 9 speeds, achieved through a wide 11-50T cassette and optimized gear ratios. The design reduces chain angles in the lowest gears, promoting a straighter chain line, which significantly enhances chain and cassette longevity. The 2-piece multi-shift pull lever allows riders to shift up to 3 gears per click, enabling quick and confident gear changes on demanding terrains.

- 11-50T Wide Range Cassette: Provides a perfect balance of high climbing capability and high-speed cruising, suitable for mountain biking, trail riding, or gravel adventures.

- Single Shift Compatibility: Recommended for eBike applications, simplifying operation while maintaining top-tier performance.

- Prime 9 Chain: Compatible with modern narrow/wide chainrings, resistant to stretching and wear, designed to increase drivetrain lifespan and efficiency.

Style & Use Case:

The BOX Three Prime 9 groupset is ideal for eBike enthusiasts seeking a reliable, low-maintenance drivetrain with excellent range and durability. Its sleek design complements both mountain and gravel bikes, making it a versatile choice for riders tackling challenging terrains or extended rides.

Innovative & Differentiating Features:

- Embraces the less is more philosophy, reducing component count for increased durability and lower weight.

- Significantly decreases chain wear and promotes longer-lasting drivetrain components.

- Designed specifically for the demands of eBike riding, providing integrated performance and robustness.
