A WORD OF CAUTION
Traveling with your bike on a roof rack backward, with your race number attached, may lead to the holder’s damage.
DON'T DO THIS:
When driving at high speeds, the frame number plate catches the wind like a sail and will slightly bend the holder back and forth weakening it. This may also lead to damage and the loss of your frame number plate.
DO THIS INSTEAD:
When mounting your bike forward-facing, there is little back and forth movement of the frame number plate.
Keep this in mind when traveling to and from races and/or between stages.
