A note from the
development team
Our goal as bicycle developers is simple: we
seek to improve experience of riding. Getting
there can be a bit more complicated.
Trek’s IsoSpeed decoupler, for instance,
which was originally developed for the first
generation Domane, was the result of an
extensive 18-month study of how a racing bike
performs over rough roads.
Since its introduction, IsoSpeed has
revolutionized race comfort technology,
bringing a new standard of compliance and
confidence in handling to road, cyclocross,
and mountain bikes in Trek’s lineup.
But Trek never stops developing. With the
all-new Domane SLR, we set out to devise a
solution that would both expand the range
and allow customization. Additionally, we
sought to offer front-end compliance that
increased efficiency
and comfort.
In development, we went directly to the
source—researching and designing adjustable
rear IsoSpeed and front IsoSpeed at the
Arenberg Forest with Fabian Cancellara and
Trek-Segafredo, then replicating a 100-meter
section in our Waterloo Performance Factory
for even more extensive testing.
After rider evaluations, structural testing,
and computer simulations, the result of our
efforts is extraordinary new ride-smoothing
technology that changes expectations of
race comfort. Hundreds of people had a
hand in making the new Domane a reality,
from engineers to product developers to
carbon techs on the Waterloo factory floor. It
wouldn’t be the bike it is today without each
of their contributions. In the end, we knew
we’d achieved something remarkable. We
hope you enjoy the magic.
Sincerely,
The Domane SLR Development Team
Domane SLR
A monumental advantage
Congratulations
If you’re reading this assembly manual,
odds are you’re about to lay hands on the
smoothest, most efficient race bike Trek has
ever created.
The all-new Domane represents a new
convention of race comfort and performance.
Born of the historic cobblestones of cycling’s
most iconic one-day races, Domane delivers
never-before-seen levels of compliance and
efficiency with three groundbreaking new
technologies: adjustable rear IsoSpeed, front
IsoSpeed, and the IsoCore handlebar.
Cycling’s roughest roads are the proving
ground of the world’s greatest equipment and
racers. These roads have conquered all.
Until now.
Domane is more than smooth.
It’s a monumental advantage.

1ISOSPEED SEAT DECOUPLER AND SEAT MAST
How it works
High position
As the adjustable seat mast slider is
moved up the seat mast, you will feel
the road surface and be more subject
road vibration.
Low position
The ride will be more comfortable
as the adjustable seatmast slider is
moved down the seat mast. You will
be more isolated from any vibration
caused by the road surface.
The IsoSpeed seat decoupler allows the seat mast to flex
independently (decoupled) from the seat tube and top
tube. The IsoSpeed decoupler provides saddle comfort over
rough pavement, while the frame maintains stiffness for
quick acceleration and increased pedaling efficiency.
The new adjustable seat mast slider changes the amount
of flex provided by the seat decoupler for a truly tuned ride.

Installing the Adjustable Seatmast
Slider and securing the seat mast.
1. Rotate the seat mast away from the frame.
2. Install the adjustable seatmast slider by fitting it
into the corresponding groove on the seat mast.
Slide it up past the hole in the bottom of the seat
mast, you will adjust its position later.
3. Rotate the seat mast so the slider contacts with
the seat tube.
4. Insert the m5 nut into the hole on the seat mast,
making sure the vertical alignment of the head
of the nut matches the vertical alignment of the
hole in the seat mast. There is a crush risk if it is
not aligned.
5. Place the spring lock washer, the flat washer and
the curved washer onto the cap screw. The dome
of the spring lock washer is curved and fits against
the head of the cap screw.
TIP
Squeeze the seat mast and
seat tube together to hold in
place during these steps.
