VTT is designed to provide the rider with fast, on-
the-fly, wide-ranging tuning adjustment to the
damping characteristics for various terrains.
Three independent damping circuits create specific
flow paths tuned to maximize pedaling efficiency
and comfort for any terrain the rider may
encounter.
These shim based damping circuits are factory
tuned for a wide audience, but may be tuned after-
market to suite any rider’s preference.
Position 1 - Soft
• High-speed preload
valve disengaged. LS
flow-path opened.
• This setting is for
casual trail riding
where comfort takes
preference over speed.
Position 2 – Firm
• High-speed preload
valve engaged. Low-
speed flow restricted.
• This setting is for
pumping thru flow trail
and additional support
for hard charging
downhill sections.
Position 3 - Platform
• Flow limited to preloaded
shim valve
• This setting provides
platform, limited
movement of the fork, for
maximum pedaling
efficiency.

The shim-based design of the VTT damper can be fine
tuned to the specific requirements of each rider.
A heavier or more aggressive rider may prefer a firmer
damping tune. Likewise, a lighter or more casual rider may
prefer a softer damping tune.
High-Speed and Platform shim stacks may be tuned
independently to provide specific damping characteristics
for each knob position. For instance a lower pedaling
platform (Position 3) may be achieved while increasing
the High-Speed damping (Positions 1 &2).
Advanced Tuning Tip:
Clamp shim thickness
controls preload valve force
in Position 2. Thicker clamp
shim reduces preload.
Thinner clamp shim
increased preload.

In the table and dynometer plots below, four standard damper tunes have been created to
demonstrate the effects on the Platform and High-Speed shim combinations. As noted
before, the Platform and High-Speed shim stacks may be independently tuned to the
needs of each specific rider.
* Total shim stack height, including High-Speed plate must be 2.3-2.9mm
