Guide des critères de sélection. Ces points sont également disponibles sous forme de texte lisible ci-dessous.
A component weight is meaningful only when the size and supplied configuration are identified. Compare like-for-like assemblies before deciding whether one bicycle component is lighter than another.
Ask what was included on the scale
Record the size, finish and installed fittings. For a wheel-related item, distinguish a bare rim from a complete wheel; for a frame, distinguish the frame alone from a frameset with fork and hardware. Packaging mass should be kept separate from product mass.
Keep the buying decision wider than one number
Weight does not answer whether the item fits the intended components or has the required validation. Read the geometry and interface information alongside the measurement. If a catalogue gives only an indicative value, ask for the basis and any agreed production tolerance before turning it into an acceptance requirement.
Exemple de scénario
One listing describes a bare rim and another describes a wheel with hub and spokes. Ask for equivalent supply configurations before comparing their weights. A lower number on the first listing does not describe a lighter complete wheel.
Points à noter
| Configuration | Identify component type, size and included fittings. |
|---|---|
| Measurement | Record the condition and basis of the quoted mass. |
| Acceptation | Agree whether the value is indicative or a controlled requirement. |
