How to acheive the right position?
1. Saddle height
The saddle height is basically determined by this calculation:
RIDER INSEAM x 0,89 = SADDLE HEIGHT
2. AeroDrive
A previous bike setup could be adapted to the Trinity Advanced SL.
Otherwise, we do recommend starting with the high position stem and
all the highest armrest position.
By setting up the AeroDrive as high as possible, you can progressively
lower the position by changing the stem.
Then, you can fine tune your setup by removing some extension
spacers.
With this procedure, you will save some time and money by avoiding
changing the cables every time you try a new position. -
Once the bar position defined, report to the different parts of this manual
to assemble your setup.

Headset Instruction
FSA N°26G2 1”1/8
The TRINITY Advanced SL
AeroDrive uses a classic FSA
headset but without the conical cap,
as the stem integrates it’s own top
cap.
Please closely follow the assembly
instructions. Any failure in the
assembly could result in serious
injury or death.
Grease elements as indicated on the
figure.
Headset Assembly Instruction
Mounting crown race on fork steerer:
1. Ensure that fork steerer is clean and free of metal chips, dirt and
paint.
2. Apply a thin layer of grease to the crown race seat on the fork
steerer.
3. Tap the crown race on to the steerer using a crown race installation
tool.
Note: Use the correct fitting on the installation tool to ensure no damage is
done to the crown race.
4. Apply a thin layer of grease to bearings, cups, races and
compression rings.
Integrated models only, insert bearings directly into headtube
bearing seat.
5. Slide fork steerer through the headtube.
6. Slide upper bearing race compression ring on to steerer and seat
against upper bearing.
7. Slide upper top cap compression ring on to steerer.
8. Slide top cap on to steerer. Ensure that the integrated cable housing
stop is facing forward.
9. Install any headset spacers and stem.
10. Install compression device or star-fangled nut and top cap.
Important: A star-fangled nut should never be installed in a carbon
steerer, use only a compression device such as the FSA
Compressor.
11. Adjust bearing preload by tightening the top screw only until all play
is absent from head assembly and bearings spin freely. Important:
The top screw is for bearing preload only. It is not a fastening screw.
Damage may occur if the top screw is tightened beyond proper
bearing preload.
12. Tighten stem bolts according to the AeroDrive stem assembly
(report to AeroDrive cockpit instruction).
