Hi all, I'm building up a Kikapu frame and wanted to change the cables on my old shifters, 06 Deore, but when I took the covers off the only way I could see to get at the cable end and shifter drum was to disassemble the shifters completely by removing the single nut under the top cover. Is this correct? If I remove this nut will the shifters spontaneously disassemble themselves in a spring loaded eruption of small parts? Is there a better, easier way?
