XO-1 spur-to-pinion adapter that includes the "Cush Drive"?

[Lizard]

Couldn't motivate myself to work on the XO-1 yet and still need to order a new rear axle carrier for it. I guess it will be next year until I try it out.

What spur to pinion adapter did you get?

I hope the plastic/plastic combo holds up. Perfekt solution then IMHO. Very lightweight, no diff, but still some 'give' because of the cushdrive. And cheap compared to Kershaw pinions if you need to try out different combinations.

Regarding the endbell screw: You could use a set screw with blue threadlock. Would be flush with the can then and should hold up. At least that's how my TP5670 came.
