EXT

Vaia Fork, 29", 30mm Drop, 20mm Axle

The EXT Vaia Fork is a purpose-built inverted dual-crown downhill suspension fork for 29" wheels, designed to deliver high torsional stability, low friction sensitivity, and a wide tuning window for aggressive bike-park and race-speed riding. With 38.5mm stanchions, a floating bushing system, and extensive air and damper adjustments, it targets riders who want precise front-end control without sacrificing small-bump compliance.

Key performance and tuning advantages for DH setups

1. Inverted dual-crown chassis with 38.5mm stanchions - Prioritizes steering precision and tracking when loads spike under hard braking, compressions, and rough high-speed lines
2. Floating bushing system (240mm overlap at sag) - Increases bushing support where it matters most in the ride height range, helping reduce binding for smoother action under side loads
3. Wide-range damper tuning - Separate high/low-speed compression and rebound adjustments, paired with low-friction seals and high dynamic response valving for controllable support and traction across changing terrain
4. HS3 air spring architecture - Two independent positive air chambers plus a tunable-volume negative chamber let riders shape mid-stroke support and improve initial sensitivity without relying on guesswork
5. Service- and heat-ready details - Pressure-release bleed buttons on both legs and an optimized inner volume to maintain lubrication for the sliding bushing system on long, demanding descents
