Engineered for the most demanding riders and the toughest tracks, the RockShox ZEB Ultimate A3 excels in the world’s hardest enduros. Featuring the new Charger 3.1 RC2 damper, this fork offers unparalleled adjustability for the perfect blend of comfort, control, and speed. The robust 38mm chassis, enhanced with vibration-damping ButterCups and a DebonAir+ spring, provides the cutting-edge technology needed for the fastest split times and striking style at the start line.

ZEB Ultimate Charger 3.1 A3 Features:

  • Charger 3.1 RC2 Damper: This latest evolution increases damping range and offers High-Speed Compression (HSC), Low-Speed Compression (LSC), and Low-Speed Rebound (LSR) adjustments. This configuration smooths out the roughest trails, giving riders precise control and comfort.
  • ButterCups: Integrated to block 20% of high-frequency trail vibrations, reducing hand and arm fatigue, and providing more control over long rides.
  • DebonAir+ Air Spring: Delivers a plush small bump response with increased air volume for additional support throughout the travel. This spring design ensures higher ride height and greater confidence on steep terrain.
  • Maxima Plush Fluid: Developed with top racers, this fluid minimizes friction, reduces suspension wear, and ensures a consistent feel across all temperatures, enhancing overall performance.
  • Bottomless Tokens: Allow easy customization of the air-spring curve to resist bottom-out on big hits for aggressive riders, or to make the suspension more linear for less aggressive front-end riding.
  • BOOST Technology: Enhances frame geometry possibilities with shorter chain stays, wider suspension pivots, a greater range of chainring options, and increased clearance for bigger tires and wider, stiffer wheels.
  • Torque Caps: Strengthen the bond between hub and fork dropout by increasing the contact surface area, resulting in a more responsive front wheel and improved control.
  • SKF Seals: These ultra-low friction wiper seals, developed in collaboration with SKF, ensure long-lasting fork performance by keeping dirt out and reducing fatigue.
  • Lightweight Machined and Anodized Crown: Adds durability and premium aesthetics to the fork.
  • Compatibility: Comes with bolt-in torque cap adapters for use with standard hub end caps and is compatible with short fenders (RockShox fender included).

With these advanced features, the ZEB Ultimate A3 is perfect for riders who demand the best performance, durability, and style on the most challenging trails.
