Product Details

Overview & Technology

RockShox BoXXer Select D2 is a gravity-focused suspension fork engineered for big hits, fast technical tracks and shuttle laps. Available in both 27.5" and 29" wheel options, the Select D2 brings 200mm of travel, 38mm stanchions and a choice of LinearXL or DebonAir-style air spring platforms depending on the SKU to deliver consistent mid- and end-stroke support. The fork combines a jounce bottom-out bumper for predictable end-stroke control, low-friction SKF wiper seals for long service intervals and a robust aluminum crown, aluminum steerer and magnesium lowers to balance strength and weight. SRAM Model ID FS-BXR-SEL-D2 and e-bike approval make this a solid choice for modern gravity rigs.

Key Features & Performance

Delta RC damper provides easy-to-use compression and independent rebound adjustments with near-silent operation so you stay focused on the trail. The damper's independent controls let you fine-tune low-speed compression and rebound without sacrificing big-hit support. Air spring options: depending on the variant you choose, the Select D2 ships with either RockShox's LinearXL air profile for a firmer mid-stroke and progressive end-stroke, or a DebonAir+ style setup for a more plush initial stroke and predictable ramp-up. Bottomless tokens let you micro-adjust progression to suit rider weight and terrain. Real-world benefit: rock gardens feel controlled, while big drops stay composed without harsh bottoms.

Fit, Construction & Compatibility

The Select D2 is built around a 1-1/8" straight aluminum steerer with 20x110mm Boost TA axle spacing and 38mm stanchions — a proven gravity standard for modern enduro and DH frames. Magnesium lowers, aluminum stanchions and an aluminum crown combine to create a fork that resists flex under heavy braking yet remains responsive on technical trails. Key compatibility notes: accepts 27.5" and 29" wheel options (model-dependent), supports up to 220mm rotors, and accommodates up to ~81mm tire width. The fork is e-bike approved and carries SRAM model ID FS-BXR-SEL-D2; always verify rake and wheel-size variant against your frame (available rakes: 44mm, 48mm, 52mm) and confirm the SKU/part number for damper/spring specifics.

Who It's For

The BoXXer Select D2 is aimed at aggressive enduro and gravity riders who want a reliable, high-capacity fork without stepping into the ultra-high-end race price bracket. It's ideal for shuttle days, park laps, and bikepark shredding where 200mm travel and stiff construction are essential. If you hit big drops, ride steep technical lines, or run e-MTB setups that need a proven downhill fork, the BoXXer Select D2 gives the control and adjustability to tune the ride for confidence and speed.

Frequently Asked Questions

Which wheel sizes are available for the BoXXer Select D2?

The Select D2 is offered in both 27.5" and 29" variants — check the SKU/variant you select. Wheel-size affects recommended rake and handling, so choose the model that matches your frame clearance and intended geometry.

What air spring and damper does this fork use?

Depending on the variant, the fork ships with either a LinearXL air spring profile or a DebonAir-style setup and features the Delta RC damper with independent compression and rebound controls. Some market/configuration listings may reference a Charger 3.2 damper; confirm the specific part number (00.4021.276.000) when ordering.

Is the BoXXer Select D2 compatible with e-bikes?

Yes — this model is listed as e-bike approved. That means the internals and seals are designed to handle the increased speeds and loads typical of electric-assist downhill rigs. Still verify frame and geometry compatibility for your specific e-MTB.

How do bottomless tokens affect feel?

Bottomless tokens adjust progression by changing accessible air volume — adding tokens increases progression and reduces harsh bottoming, while removing tokens gives a more linear, plush feel. Use tokens to tune the end-stroke support based on rider weight and preferred bottom-out characteristics.

What maintenance interval should I expect?

RockShox recommends regular lower-leg service and seal inspection depending on use — for heavy gravity use, inspect seals and oil every 30–50 hours and perform damper/air spring servicing at longer intervals or annually. The low-grab SKF wipers extend service life but don't eliminate regular maintenance.

What rotor size and tire width does it support?

The Select D2 supports up to a 220mm brake rotor and accommodates tires up to approximately 81mm wide (depending on rim width). Always test fit your chosen wheel, rotor, and tire combination before final installation.

Buying Guide

When choosing a downhill/gravity fork, prioritize travel, stanchion diameter and axle standard. The BoXXer Select D2 offers 200mm travel and 38mm stanchions that deliver the stiffness and control needed for high-speed runs and heavy braking. Consider wheel size (27.5" vs 29"), rake, and whether you need e-bike approval to match your frame and riding style. Evaluate spring type and damper: riders who prefer a firmer mid-stroke and strong end-stroke support will like LinearXL, while those wanting a bit more plush initial compliance may favor DebonAir-style setups. Look for easy adjustment and durable seals for long service intervals on shuttle and bikepark days.
