A road bike is light but delicate, especially if the frame is carbon. Thin tubes and a rear derailleur that sticks out mean careful packing matters. This guide covers protecting a road bike for transport or shipping, with the wheel removal, spacers, and derailleur care that prevent the most common damage.
Pro tip: A hard-shell bike case protects a carbon frame far better than cardboard for repeated or long moves.
Watch out: Never ship a road bike without axle spacers. Empty dropouts and fork legs bend easily under box pressure.
