A note from the
development team
Our goal as bicycle developers is simple:
we seek to improve the experience of riding.
Getting there can be a bit more complicated.
Trek’s IsoSpeed decoupler, for instance,
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
revolutionised race comfort technology,
bringing a new standard of compliance and
confidence in handling to road, cyclocross
and mountain bikes in Trek’s line-up.
But Trek never stops developing. With the
all-new Domane SLR, we set out to devise
a solution for customisable compliance and
greater efficiency and comfort at the front end.
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-metre
section in our Waterloo Performance Factory
for even more extensive testing.
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

1ADJUSTABLE REAR ISOSPEED DECOUPLER AND SEATMAST
How it works
The Adjustable Rear IsoSpeed decoupler allows the seatmast to flex independently (decoupled) from the seat tube and top
tube. The decoupler provides saddle comfort over rough roads, while the frame maintains stiffness for quick acceleration and
increased pedalling efficiency. The new adjustable seatmast slider changes the amount of flex provided by the decoupler for
a truly tuned ride.

Higher position
As the adjustable seatmast slider is
moved up the seatmast, you will feel
the road surface and be more subject
to road vibration.
Lower position
The ride will be more comfortable
as the adjustable seatmast slider is
moved down the seatmast. You will
be more isolated from any vibration
caused by the road surface.

1INSTALLING THE ADJUSTABLE REAR ISOSPEED DECOUPLER AND SEATMAST
Installing the seatmast
1. Apply grease to the bore holes of the seatmast
and to the bore holes on the frame.
2. Insert the IsoSpeed axle into the seatmast
as shown.
3. Place a bearing and then a pivot locating washer
onto the pivot bolt. Repeat so you will have two
bolt assemblies. If you are reusing a bolt, clean
the threads and apply Loctite 242.
NOTE
The pivot locating washer is installed between the
IsoSpeed seatmast and the IsoSpeed bearing.
4. Align the bore holes in the seatmast with the
opening in the frame.
5. Pass one of the pivot bolt assemblies from Step 3
through the bore hole and thread it into the
IsoSpeed axle.
6. Insert a 6 mm Allen key into the non-drive side of
the IsoSpeed axle to hold it steady (6a). Insert a
5 mm Allen key into the pivot bolt and turn it to
engage the threads (6b). Do not fully tighten.

7. On the non-drive side, insert the other pivot bolt
assembly from step 3 through the bore hole and
thread it into the IsoSpeed axle.
8. Insert 5 mm Allen keys into both pivot bolts and
slowly turn each clockwise. Turn only until snug.
Do not over-tighten.

9. Hold the non-driveside pivot bolt with the Allen
key (8a). Using a torque wrench, tighten the
driveside pivot bolt by turning it towards the
front of the bike to 8 Nm maximum (8b). Turn
until the wrench 'clicks' to ensure proper seating
and tightness.

11. Remove excess
grease with a
cloth. Align the
Rear IsoSpeed
cover, drive-side,
and snap into
place. Repeat
for the Rear
IsoSpeed cover,
non-drive-side.
NOTE
A correctly installed
seatmast moves freely.
If it does not, reinstall
and make sure that all
hardware is installed
correctly.

1INSTALLING THE ADJUSTABLE REAR ISOSPEED DECOUPLER AND SEATMAST
Installing the adjustable seatmast
slider and securing the seatmast.
1. Rotate the seatmast away from the frame.
2. Install the adjustable seatmast slider by fitting it
into the corresponding groove on the seatmast.
Slide it up past the hole at the bottom of the
seatmast. You will adjust its position later.
3. Rotate the seatmast so the adjustable seatmast
slider contacts the seat tube.
4. Insert the m5 nut into the hole on the seatmast,
making sure that the vertical alignment of the
head of the nut matches the vertical alignment
of the hole in the seatmast. If it is not aligned,
there is a crush risk.
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 seatmast and
seat tube together to hold
in place during these steps.
