The bolts will not fit SRAM Hidden Bolt cranks that thread directly into one of the crank arms. I have a 2012 Red Exogram crank but there are many others with the same bolt. It's a waste of money on these cranks, and standard fasteners are better because they use larger hexes, so they're less likely to fray. The stock ones fit the 1x drivetrain, I just wanted shorter bolts so I didn't have to screw them in until now. Your rings work great, but these studs won't fit many of us.
