I recently picked up this Ritchey crank with hopes that I could use it for a single speed, but I can't identify what the interface is for either a spider or a chainring with an integrated spider like those offerred by Homebrewed Components. The OD of the spline is about 36mm. There are ten "teeth" on the spline. The threaded portion for the lockring (which I also don't have) is about 32mm. Can anyone help?
