Περιγραφή
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.
TECHNOLOGY AND FEATURES
CORE FEATURES

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
• Double crown is available with interchangeable 20mm and 15mm titanium grade 5
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)
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
Larger compression valve
reduces friction and maximizes
oil flow.
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.
Fork structure
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.
titanium ti gr 5 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 forthe 15mm axle!
titanium ti gr 5 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.

Fork structure
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.
Double Crown
Vaia will be available with two different top crowns:
• 10 mm drop for headtube from 107mm to 127mm
• 30 mm drop for headtube from 127mm to 147mm
We got you covered
Dedicated mudguard
Dedicated mudguard protection, directly mounted on the
stanchion guards, available for purchase separately as an
accessory.
