Do I need spacers in place of the third sprocket or can I just take it off, use the same bolts and go? I tried reading up on the subject but am getting different answers. Thanks in advance all February 21, 2021 at 15:07 #581390 Sunspot Outer ring goes away, FD limit screw is adjusted to accommodate the 2X and eliminate overrun of the chain. Job done! Same can be done on the low side too.
