    Changeover to 1X9 on a Moonlander using Blackspire stuff

    Did not like any arrangement of stuff to shift from 20-22 to 37-39 so in the trash it went.

    The change over and putting the Blackspire RingGod, sprocket, spider, and BlackGuard on is fairly simple once you get tall the parts. I had to order from England France and Canada along with US to get the stuff at reasonable prices.

    No dealer in US would order the Blackspire 58BCD stuff. You can order directly from Blackspire if you want the stuff.

    buy:
    ring god 94bcd
    black guard 58 bcd
    sprocket 58 BCD your choice I used Spec TA 29 tooth
    spider 58/94
    double chainring bolts and 12mm problem solver inner bolts
    5 2.2mm inner chain ring spacers
    one additional bb spacer and
    cut one of the supplied outter bb spacers down to 5MM thick.

    add one spacer to bottom bracket same location as A1 spacer (moves crank arm out 2.5 more mm)

    cut one of the factory tapered spacers down to 5MM thick and use it on the non sprocket side

    assemble the crank set using the 2.2mm spacers on top of the spider where black guard bolts over the cutout for the bolts to make a level space to tighten up, and then attach your sprocket and ring god.

    fits PERRRFECT and has plenty of clearance....chain is low enough to not need guides or additional chain retention stuff

    If you choose to use large sprockets 39+ you can also use a Blackspire stinger by making a bracket with an .300 offset for the roller, to move it out...and eliminate the additional bb spacer...
