Specifications

Experience ultimate performance with the RockShox BoXXer Ultimate D1 Suspension Fork (27.5'', 200mm Travel) - the pinnacle of downhill mountain biking engineering and innovation. Designed for gravity-defying descents and aggressive trail riding, this high-performance suspension fork combines premium materials, advanced damping technology, and cutting-edge features to elevate your ride.

Materials & Construction:

Built with a robust 38mm aluminum chassis and aluminum stanchions, the BoXXer Ultimate D1 guarantees durability and stiffness where you need it most. Magnesium lower tubes reduce weight without sacrificing strength, ensuring responsive handling and a lightweight profile. The steerer tube is crafted from durable aluminum, accommodating 1-1/8'' steerers, with short and tall crown options for customized fit.

Performance & Engineering:

Equipped with the innovative DebonAir+ twin tube air spring, this fork delivers a coil-like, butter-smooth small bump sensitivity, enhanced support throughout its 200mm travel, and increased ride height for added confidence on steep descents. The Charger 3 damper, tuned specifically for the BoXXer chassis, offers precise adjustments with High & Low Speed Compression and Low Speed Rebound, allowing riders to dial in their perfect ride feel.

Components & Technologies:

- ButterCups Technology: Reduces up to 20% of high-frequency trail chatter, minimizing hand and arm fatigue on long, rugged rides.

- DebonAir+ Twin Tube Air Spring: Balances plushness with support, ideal for aggressive downhill and enduro riding.

- Premium Fender Compatibility: Includes a RockShox Bolt-On Fender to protect your setup from mud and debris.

- Disc Brake Compatibility: Designed for high-performance disc brakes, suitable for complex, technical descents.

Style & Use Case:

Visually striking in the exclusive BoXXer Electric Red colorway with a modern graphics package, this fork is as stylish as it is functional. Perfect for downhill racers, enduro riders, and gravity-oriented mountain bikers, its aggressive styling and high-end features make it the ideal choice for tackling steep, technical trails and racing against the clock.

Innovative & Differentiating Features:

- Signature All-New 38mm Chassis: Enhanced stiffness for improved steering precision and control.

- Taller Ride Height & Support: Provides added confidence when descending challenging terrain.

- Adjustable Air Pressure & Bottomless Tokens: Fine-tune your suspension for various trail conditions and rider weight.

- Designed for eMTB: Optimized for electric mountain bikes, offering stability and durability for powered descents.

Take your downhill and enduro riding to new heights with the RockShox BoXXer Ultimate D1 Suspension Fork - engineered for precision, built for durability, and designed for thrill-seeking riders demanding the best in suspension technology.
