particularly carbon parts, need extra care when assembled. These components must be installed using a calibrated torque

wrench to make sure every bolt is at the right torque setting to prevent damage.

GALLIUM PRO DISC 338A: 4.1. Headset Installation

Install the 3D headset (9) according to

the presst assembly guide. You can

choose from 3 dierent heights: 25mm,

15mm or 0mm.

IMPORTANT:

No more than 30mm of spacers can be placed between the

stem and the top cap of the 3D system.

The steerer must be trimmed no more than 5mm above the

stem. The use of more than 5mm of spacers above the stem

could void the eciency of the compressor.

These practices will automatically cancel any warranty

claim against the manufacturer.

post (3). Apply carbon paste inside the frame’s
