What do technical officials check in transition?

Section 5 of the Race Competition Rules sets the transition area conduct rules:

• A competitor may only have a bare torso when moving between the swim exit or entry and their transition position.
• Bikes must be mounted and dismounted at the designated zones (one complete foot on the ground after the mount line, or before the dismount line).
• Competitors must rack only their own bike, at their designated rack location, in a stable position, by either the seat or both brake hoods.
• All equipment must be placed at the competitor's own bike rack location.
• Competitors must not interfere with another competitor's equipment. If it happens accidentally, they must put it back in its former position and state before proceeding.
• Marking a position in transition is forbidden. Marks and objects used for marking are removed and competitors are not notified.
• Only equipment to be used in the competition can be left in transition. All other belongings must be removed before the competition starts.
