INSPIRED BY DH, MADE FOR GRAVITY

The wait is finally over. EXT is proud to unleash the Vaia, a dual-crown inverted
DH fork, distinguished from all others in its class. This groundbreaking product
breaks away from familiar suspension design and is packed with innovation and
cutting-edge tech for the gravity focused MTB world.

While the Vaia completes EXT’s DH lineup, it's thoughtful design and
adaptability simultaneously lends itself to aggressive enduro bike and e-bike
applications as well. With travel options from 170mm to 200mm, and the ability
to change between 15mm and 20mm axles, the Vaia is both a powerful and
versatile contender in the MTB market.

CORE FEATURES
• Built entirely in 7075 and 7050 T6 alloy and Grade 5 Titanium
• Tapered 38.5 stanchion tubes optimize the strength to weight ratio, offered with
our proprietary surface finish
• Floating bushing system design with an impressive overlap (240 mm around SAG
position) with 200 mm travel, ensuring consistent sensitivity and torsional
stiffness for riding precision while braking and cornering
• Adjustable high/low speed compression and rebound cartridge with low friction
seals, high dynamic response valves and turbulent flow, assures performance in
extreme working conditions
• HS3 air cartridge unit with 2 independent positive air chambers as well as an
innovative negative chamber with a tunable volume design for increased
sensitivity and adjustability
• Pressure release bleed buttons to release air on both fork legs
• Optimized inner volume design ensures maximum lubrication for sliding
bushing systems
• Unique double crown design offers 2 offsets, from 44 to 48 mm, enhancing
personal adjustment on steering geometry without having to purchase additional
crowns
• Available with interchangeable 20 mm and 15 mm Grade 5 Titanium wheel axles
for both maximum stiffness and rigidity
• Dedicated stanchion protection with available bolt on fender
• Weight: 3195 gr (in 200 mm travel with 20 mm wheel axle, cut steerer tube, oil
included)

1 STEM, 2 OFFSETS!
Thanks to a proprietary cam stem design developed with Mojo Rising, the Vaia
offers two offset options (44 and 48 mm) with only one stem and crown, allowing
for personal adjustment of steering geometry. The fully machined double crown
is made from 7075 aluminum.
DOUBLE CROWN
Vaia will be available with two different top crowns:
• 10 mm drop for headtube from 107 mm to 132 mm
• 30 mm drop for headtube from 127 mm to 152 mm
SLIDING BUSHINGS
We have implemented technology derived from our motorsports heritage to
provide optimal bushing performance, via floating bushings.
The new DU bushing material in the Vaia fork is manufactured to precise
tolerances for each assembly and works seamlessly with our specially
formulated EXT oil. This combination ensures zero stiction and exceptionally low
friction, even under high side loads.
Like in MX bikes, our unique DU guiding system, featuring a specially designed
long bushing overlap, providing maximum guidance and optimal torsional rigidity
for the stanchions. We’ve named it the CGB (Continuously Guided Bushing)
system, which also boosts dynamic stiffness. Optimized inner volume design
ensures maximum lubrication for sliding bushing systems.
This technology inherently allows for optimal bushing overlap that increases
throughout fork travel but also has the advantage of incorporating a radial float
capacity that constantly adapts to any forces exerted onto the fork tubes by the
wheel. As such this small degree of float may be perceptible while unweighting
the system from a static state such as lifting the front of the bike in the parking lot.
However, in actual use this is not detectable by the user.
TITANIUM TI GR5 WHEEL AXLE
Twin hexagonal Grade 5 Titanium (Ti Gr 5) floating wheel axle guarantees perfect
wheel alignment and excellent torsional stiffness. Available in 15mm diameter
version for enduro wheels and 20mm for DH, with no need to replace any major
components of the fork; just add an adapter for the 15mm axle!
TITANIUM TI GR5 HARDWARE
Bolts, nuts, washers, and other hardware components made of Grade 5
Titanium DIN 912 spec, used in aerospace and industrial applications for its high
mechanical strength, light weight, and corrosion resistance characteristics.
We know that even the small things matter, so all details were considered.
NEW SELF CONTAINING AIR CARTRIDGE
Vaia features the EXT HS3 technology, a unique hybrid air spring system with two
separate positive air chambers that work in tandem with a large-volume, self- equalizing negative air chamber. HS3 is designed to provide excellent mid-stroke

support around the dynamic sag position, while also delivering outstanding
sensitivity and bottom-out protection. All passages and ports are designed to
minimize air pressure drop during long stroke high-speed movement, minimizing
hysteresis.
The special design improves heat dissipation and better isothermic conditions,
balancing pressure variations and ensuring consistent performance even on
long descents.
HS3 WITH EXTRA TUNING
The advantages of our HS3 system doesn’t end there. We have introduced
volume spacers to our current HS3 system to further increase the range of
tunability. By adding or removing tokens you can both reduce and increase the
volume of the chambers independently.
The ++ chamber offers further tunability within the end stroke of the air spring
curve. This tuning allows for significantly increased end stroke ramp up while
minimizing impact to the initial and mid stroke characteristic.
The negative chamber volume is also tunable with volume spacers. Adding
spacers to the negative chamber increases support throughout the entire travel
range without affecting the curve. This allows for further air spring curve
optimization for different rider wights and levels of aggression.
3 WAY-ADJUSTABLE CARTRIDGE
A high-flow, 3-way adjustable hydraulic cartridge is the core of the Vaia fork,
featuring independent high/low speed compression and rebound adjustments.
Maximum hydraulic fork tunability allows each rider to dial in the damping forces
to perfectly match their riding style and weight. High dynamic response valves
and turbulent flow ensure optimal performance in extreme working conditions.
The options for customizing this fork are virtually limitless.
WE'VE GOT YOU COVERED
Dedicated mudguard protection, directly mounted on the stanchion guards,
available for purchase separately as an accessory.
