RockShox BoXXer Ultimate D1 Suspension Forks

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 colorway BoXXer Electric Red with an all-new graphics package.

Premium fender compatibility (RockShox Bolt-On Fender included with purchase)

Short and tall crown options available to accommodate different head tube lengths.

Charger 3 damper tuned for BoXXer’s updated chassis and spring. Featuring High Speed Compression, Low Speed Compression, and a revamped Low Speed Rebound, every click is meaningful and exact.

ButterCups block 20% of high-frequency “trail chatter” to reduce hand and arm fatigue
