    Need help with Blackspire chainring bolts

    I just ordered a Blackspire 28T chainring for my Sram XO1 1x11 drivetrain. I called Blackspire up to make sure no compatibility issues. The guy over the phone told me to use my existing Sram bolts. Well, as you can see they are no where close to being compatible. Does anyone know what bolts are to be used with this chainring? Thanks!

    Looks to me like the Black Spire chain ring has the chain ring nuts integral to the ring. You stick it on so the protrusions go into the spider and the bolts then thread directly into the chainring to fasten it.
    Do the math.

    The Blackspire chainring is threaded. Unscrew the bolts from the nuts used with the old one and they should thread directly in the Blackspire.
