To remove the 3D bearing holder, insert the Park Tool
RT-1 and then tap it carefully until the spacer comes out.
Position the headset inside the head tube. Place
the top 3D assembly with the headset bearing inside
(this will prevent the sleeve from getting damaged).
Add the compression ring (4) on top of the bearing,
then add the press fit 3D system tool and softly press
down the assembly until it bottoms out using a Bearing
Cup Press (Park Tool HHP-2). Then, insert the bottom
bearing (5), micro spacers (3) and top cap (2), slide the
fork and stem and measure the steerer length needed.
For the 0mm setup , do not use the plastic sleeve.
Install the 3D bearing holder (6) with grease applied
directly inside the frame.
First, you must assess which
setup
suits your needs:
25mm, 15mm or 0mm.
