The adjusters are disabled because they are temporarily discontinued. Steeda, MM, UPR, ect are all available though. Once and if the Fiore adjuster is back, we will notify you guys.
To add to what John said, if you are set on the Fiore style, the McLeod adjuster is IDENTICAL to the Fiore with the only exception is that it's anodized red. We have plenty of Fiore quadrants as well.
