Zeb Ultimate Charger 3.1 RC2 Fork 2025

The burliest fork in the Rockshox single-crown fork family, the ZEB is made for the toughest Enduro stages, hard hitting bike-park riders and is also a fantastic companion for a rapid e-mtb frame. 

Equipped with the latest Charger 3.1 RC2 damper, ZEB gives riders exceptional adjustability for the right balance of comfort, control, and speed. Alongside this flagship damper, the stout 38mm chassis rides on vibration-killing ButterCups and a DebonAir+ spring. 

FEATURES

• NEW To meet the demands of the world's best riders, Charger 3.1 is a brilliant evolution of our proven damper platform. With increased damping range and High Speed Compression, Low Speed Compression, and Low Speed Rebound adjustments, Charger 3.1 smooths out the roughest trails.
• NEW Charger 3.1 RC2's adjustment range is broader—with less compression damping in the LSC open position and additional support in the HSC closed position, you get the traction, control, and comfort you need to charge dicey lines all day.
• NEW Ever on the quest to eliminate friction, a new bushing package further reduces friction with an updated process at the factory level to give riders a better feel right out of the box.
• ButterCups block 20% of high-frequency “trail chatter”. Limiting these vibrations massively reduces hand and arm fatigue leaving you feeling fresh with more control.
• DebonAir+ air spring is built to strike the perfect balance of what riders really want: a butterlike small bump feel, increased air volume to add support throughout the travel, and higher overall ride height for more confidence when things get steep.
• Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride.
• Bolt-in torque cap adapters now included for use with standard hub end caps.
• Lightweight machined and anodized crown for premium looks and durability.
• Available in Signature colourways Electric Red, Slab Grey or Ultimate High Gloss Black.
• Ultra-low friction SKF wiper seals provide long lasting fork performance and improve overall suspension feel.
• Short fender compatibility. (RockShox fender included)

Charger 3.1 Damper - 

Tweaked to deliver amazing levels of traction, the broad adjustment range of the Charger 3.1 can easily be dialed to give you the support you need, even on the fastest of tracks. 

Updated low-speed compression circuit - 68% more oil flow means reduced damping when LSC is in the open position for more comfort.

All new high-speed compression pyramid - Increased damping when HSC is in the closed position so you can add the exact amount of support you need.

Other new features added include - Shim tune kits (two compression and three rebound tunes available, you can customize your damper just the way you like), new internal floating piston coil spring that boosts consistency and control and newly designed mid valve check spring for further reduced compression damping, and therefore improved traction.
