  Make sure that both fork dropouts are engaged in the rack before clamping. Make sure both dropouts are
  clamped with equal force. If only one dropout is engaged and the bike tips over, the leverage can exert
  great force that may damage the dropout. If your bike tips over, have the dropouts examined by a
  professional bicycle mechanic.
