For the warranty to be valid, the bicycle must be fully assembled by an authorized Argon 18 dealer. High-end components, particularly carbon
parts, need extra care when assembled. Those components must be installed using a calibrated torque wrench to make sure every bolt is at the right
torque setting to prevent damage.
No more than 30mm of spacer can be place between the stem and the top cap of the 3D system.
And the use of more than 5mm spacer on top of the stem could void the eciency of the compressor.
These practices will automatically cancel any warranty claim against the manufacturer.

rotation of the handlebar. Insert the cable trough the shifter, then
insert the cable and the housing with a ferrule in the head tube.
Rear section: With a magnet, get the rear brake cable out of the frame,
and pass it trough the rear cable stopper. Measure the rear housing
correctly to avoid interference with the rider’s left leg. Fix the cable to
