The Citizens have already been in competitive action during the summer months, as they faced Danish side Lyngby BK in the preliminary round of the Europa League, losing 4-0 on aggregate over the two legs.
Bangor have also been busy in the transfer market, securing some impressive signings, including Spaniard Anderson Cayola, young striker George Harry from Wrexham and defender Danny Holmes from York City.
Having tried out a variety of players thus far and used different formations, Flint manager Andy Holden will see this match as another great opportunity to test the mettle of his side, as he continues his preparations for the big kick off next month.
The action gets underway at Cae-Y-Castell at 7-30pm. Admission is £5 for Adults and £3 for Juniors/Senior Citizens.
