High-speed composure defines the BoXXer Select 29in Boost Fork for modern DH builds
What Our Gearhead® Experts Are Saying:
"If you’re running a 29er downhill bike, this fork gives you stability without feeling vague. The LinearXL spring keeps it planted through braking bumps, and it holds up well on longer, rough tracks."
When 29in wheels are rolling fast and the course is breaking down, control becomes everything. The BoXXer Select 29in Boost Fork from RockShox is built to keep our posture steady and our vision clear when the track gets rough.
LinearXL brings a position-sensitive linear curve that stays consistent through the travel, reducing unwanted surprises under heavy braking and high-speed impacts. A jounce bottom-out bumper manages full-travel events with confidence, while the Charger 3.2 RC damper delivers intuitive compression and rebound tuning. The 38mm chassis tracks precisely without excessive harshness, helping us maintain traction through rock gardens and blown-out berms. Designed for Boost spacing and modern downhill frames, this fork keeps 29in builds composed at race pace.
