Flex Backing Plate

[POPPAJ]

Any word on when the replacement BP for the Flex will arrive and be sent Out?

The final version of the Flex BP is 5.5" and depending upon where you purchased it, they should've sent you the replacement if you Flex did not already come with the new 5.5" BP. The new one has a layer of white material in between the hard plastic section the gears drive and the velcro section for pads.
