I have a few “unicorn” rears I’m letting go that I have been sitting on for awhile. The reason they are unique is because they are the lightest of the light in a Winters K837S style sprint rear. There are parts on these that aren’t available to buy any longer because supply for them ceased to exist. You cannot build a any lighter 10” ring and pinion style rear.
