RockShox BoXXer Ultimate Suspension Fork - 2023

The All New RockShox BoXXer fork has been redesigned from top to bottom by the Worlds fastest racers, for the Worlds fastest racers and of course, for you. With a brand new 38mm chassis that's got the DebonAir+ twin tube air spring that will have you thinking it’s a coil. Paired with a Charger 3 RC2 damper, BoXXer Ultimate takes you straight to the top step of the podium. And with our new crown adjustment lines, setup is a breeze—no rulers required. 

• NEW 38mm chassis designed to meet the needs of the world’s fastest racers with balanced stiffness and ride quality.
• NEW DebonAir+ twin tube air spring strikes the perfect balance between butter-smooth small bump feel, added support throughout the travel, and taller ride height for confidence when things get steep.
• NEW Signature colour way BoXXer Electric Red with an all-new graphics package.
• NEW RockShox premium fender compatibility (RockShox bolt-on fender comes in the box for AM forks, and sold separately for OE forks).
• NEW Lightweight machined and anodized crown for premium looks and durability.
• NEW Crown height gradient creates a visual guide to simplify setup, no ruler required.
• Charger 3 RC2 damper for BoXXer. Featuring High Speed Compression, Low Speed Compression, and a revamped Low Speed Rebound, every click is meaningful and exact. This allows the rider to tune to perfection with every click.
• ButterCups block 20% of high-frequency “trail chatter” to reduce hand and arm fatigue, leaving you feeling fresh with more control.
• Ultra-low-friction SKF wiper seals provide long-lasting fork performance and improve overall suspension feel.
• Maxima Plush damping fluid reduces friction and silences damper noise.
• Maxima Plush Dynamic Suspension Lube reduces friction, lasts longer, and enhances suspension performance ride after ride.
