How the heck do I install a chainring on this crank?
I got a pair of Sugino XD-2 double crank arms and some SRAM chainrings. I'm now trying to put the chainrings on, but I'm completely stumped as to how I'm supposed to tighten the chainring bolt that lies directly underneath the crank arm.
As you can see, there's maybe a centimeter of clearance....
