The Mach 4 SL World Cup XX build is tuned for when the pace turns unforgiving. Pivot's size-specific carbon frame delivers exceptional stiffness without added weight, while the XC-tuned DW-Link suspension keeps power transfer crisp and traction planted through roots, rocks, and braking bumps. Adjustable rear travel and Factory-level suspension components let us dial the bike in per course, so the build stays out of the way when it matters most. What Our Gearhead® Experts Are Saying:"I've ridden the World Cup XX build back-to-back with lower-tier kits, and the difference is obvious. The bike feels lighter on accelerations, more precise under power, and composed at race speed. The XX SL Transmission shifts flawlessly when I'm pushing hard, and the Fox Transfer dropper adds real confidence on technical XC descents."Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive.
