Fixed Adjustable Nut is a 4-position plate for using the Portage Dropout system for chainstay length adjustment, but not single speed use.
Allows adjustments without using Set Screws, and gives a more durable attachment than nuts used for sliding mode.
FANs work with both Classic and UDH Adjustable dropouts. FANs are now standard on all Esker product delivered after mid-2022. Dropout plates are sold without hardware, make sure to add these in when ordering adjustable plates.
