Pivot

Mach 4 SL World Cup XX SL Eagle Transmission Mountain Bike

What Our Gearhead® Experts Are Saying:

"This build feels purpose-built for the highest level of XC racing. The frame stiffness, suspension efficiency, and XX SL Transmission work together seamlessly. It’s a bike that rewards clean lines and aggressive riding, especially when the course gets technical."

The Mach 4 SL World Cup XX build represents Pivot’s no-compromise approach to cross-country racing. Designed around an ultralight, size-specific carbon chassis, it delivers immediate acceleration and precise handling that shines on modern, technical XC tracks. The DW-Link suspension platform keeps the bike efficient under power while remaining active and controlled when terrain demands it.

Equipped with SRAM’s XX SL Eagle AXS Transmission T-Type drivetrain, this build offers class-leading shifting consistency with a direct-mount interface designed to perform under load. Fox Factory suspension components provide refined damping and lightweight performance, while the RockShox Reverb AXS dropper integrates seamlessly into the bike’s wireless ecosystem for confident transitions between climbing and descending.

Whether lining up for a World Cup circuit or chasing marginal gains in marathon XC events, the Mach 4 SL World Cup XX build is engineered for riders who demand the lightest feel, sharpest response, and most reliable performance available.
