Default Re: Manic Mechanic sprocket adapter


Excellent description!

I actually machine the sprocket adapters to fit slightly on the tight side of nominal. This ensures a thou or two tight clamp to the hub. It isn't necessary, it's just part of the design intent.

There is nothing consistent, (form one hub to the next), to postively register the sprocket other than the sprocket mounting bolts. The 3/8-16 button head bolts typically measure .370". I use a letter "V" drill, (.377"), to drill the holes in the sprocket. Once the three bolts are installed, the run-out is .005" or less.
