I swapped my 2012 Kona Operator to an SLX shifter and Zee derailleur. After I came home from riding DH on Saturday, I noticed that the cover on the bottom of my shifter was missing, so I can see all the guts inside now. I checked my car, and it was no where to be found, so the cover is gone. Does anyone know where I can get a replacement? The shifter still works, I just don't want to ruin it by rusting the insides out or getting them jammed with dirt/mud.
