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. These components must be installed using a calibered torque wrench to make sure every bolt is at
the right torque setting to prevent damage.
